In the oil and gas drilling industry, the tubing pup joint is a critical component for the completion of a well. The pup joint allows the driller to change out the drill pipe without having to pull out the entire string of pipe from the well. This is a common practice, especially when drilling deep wells. Because of this, the tubing pup joint is one of the most important joints in any well.

Tubing pup joints are small-diameter tubing that is used in conjunction with casing to complete a well. The pup joint is run in the hole and cemented to the casing, and then the production tubing is run over it and attached. This arrangement allows for the use of smaller-diameter production tubing, which results in less pressure drop and improved production. The pup joint is usually located in the last few feet of the tubing string.

Pursuant to subsection 38(1) of the Special Import Measures Act, the President of the Canada Border Services Agency made preliminary determinations of dumping and subsidizing on December 12, 2011, respecting the alleged injurious dumping and subsidizing of oil country tubular goods pup joints, made of carbon or alloy steel, welded or seamless, heat-treated or not heat-treated, regardless of end finish, having an outside diameter from 2 3/8 inches to 4 1/2 inches (60.3 mm to 114.3 mm), in all grades, in lengths from 2 feet to 12 feet (61 cm to 366 cm) originating in or exported from the People"s Republic of China.

On July 22, 2011, the Canada Border Services Agency (CBSA) received a written complaint from Alberta Oil Tool (AOT), a division of Dover Corporation (Canada) Limited of Edmonton, Alberta, (hereafter, “the Complainant”) alleging that imports of certain pup joints originating in or exported from the People"s Republic of China (China) are being dumped and subsidized and causing injury to the Canadian industry.

The Complainant provided evidence to support the allegations that certain pup joints from China have been dumped and subsidized. The evidence also disclosed a reasonable indication that the dumping and subsidizing had caused injury and are threatening to cause injury to the Canadian industry producing these goods.

On September 12, 2011, pursuant to subsection 31(1) of SIMA, the President of the CBSA (President) initiated investigations respecting the dumping and subsidizing of certain pup joints from China.

On September 13, 2011, the Canadian International Trade Tribunal (Tribunal) commenced a preliminary injury inquiry, pursuant to subsection 34(2) of SIMA, into whether the evidence discloses a reasonable indication that the alleged dumping and subsidizing of certain pup joints from China have caused injury or retardation or are threatening to cause injury to the Canadian industry producing the goods. On November 14, 2011, pursuant to subsection 37.1(1) of SIMA, the Tribunal made a preliminary determination that there is evidence that discloses a reasonable indication that the dumping and subsidizing of certain pup joints from China have caused injury or retardation or are threatening to cause injury.

On December 12, 2011, as a result of the CBSA"s preliminary investigations and pursuant to subsection 38(1) of SIMA, the President made preliminary determinations of dumping and subsidizing with respect to certain pup joints originating in or exported from China.

Of the other producers certified to produce the like goods in Canada, only Tenaris Canada (Tenaris), of Sault Ste. Marie, Ontario, confirmed that they are manufacturing them. Tenaris produces like goods which are premium pup joints in relatively small quantities and provided a letter supporting the complaint.

As part of the section 20 inquiry, RFIs were sent to all known producers of pup joints in other countries (excluding China). This list of certified producers was obtained directly from the American Petroleum Institute (API). A total of 139 RFIs were sent to these producers requesting domestic selling price and costing information for pup joints produced at their facilities.

Oil country tubular goods pup joints, made of carbon or alloy steel, welded or seamless, heat-treated or not heat-treated, regardless of end finish, having an outside diameter from 2 3/8 inches to 4 1/2 inches (60.3 mm to 114.3 mm), in all grades, in lengths from 2 feet to 12 feet (61 cm to 366 cm) originating in or exported from the People"s Republic of China.

Pup joints are oil country tubular goods (OCTG) made from carbon or alloy steel pipes used for the exploration and exploitation of oil and natural gas. These pipes may be made by the electric resistance welded (ERW) or seamless production method, and are supplied to meet American Petroleum Institute (API) specifications 5CT or equivalent standard. 5

Pup joints are primarily used for the purpose of adjusting the depth of strings or down hole tools, particularly where exact depth readings in a well are required for any given purpose, such as setting valves, packers, nipples or circulating sleeves. Pup joints are also used with down hole pumps. The number and lengths of pup joints may vary widely from well to well, depending on the various equipment and performance requirements established by engineers of the purchasing end users.

Pup joints may range from 2 feet to 12 feet in length with a permitted tolerance of plus or minus three inches. The sizes are generally 2, 4, 6, 8, 10 and 12 feet in length.

The input pipe is produced in accordance with API 5CT, and may be produced using either seamless or ERW material. While pup joints may be made with ERW pipe, the Canadian market employs predominantly seamless OCTG. All pup joints produced by the Complainant are seamless products. 6

The pup joints subject to these investigations are, by virtue of the characteristics such as the outside diameter range, essentially short lengths of OCTG tubing.

Theoretically, subject pup joints may be supplied to meet any grade including and not limited to, H40, J55, K55, M65, N80, L80, L80 HC, L80 Chrome 13, L80 LT, L80 SS, C90, C95, C110, P110, P110 HC, P110 LT, T95, T95 HC, and Q125, or proprietary grades manufactured as substitutes for these specifications. The most common demand in the Canadian market is for J55 or L80 grades.

The grade numbers define the minimum yield strength required of the grade in kilo-pounds [force] per square inch (“ksi” or 1,000 pounds per square inch). Pup joints may also be made to proprietary specifications. The Complainant makes or has the capability to produce pup joints in any of these specifications/grades.

As with all OCTG, a standard pup joint must be able to withstand outside pressure and internal yield pressures within the well. Also, it must have sufficient joint strength to hold its own weight and must be equipped with threads sufficiently tight to contain the well pressure where lengths are joined.

There is a small market segment for perforated pup joints. These are pup joints with holes in the body of the pup joint (usually 3/8 inch although they may have holes or slots of various sizes in the body). The product is produced with API 5CT tubing, though once perforated the product no longer conforms to an API 5CT specification, since it no longer meets the yield strength requirements. Perforated pup joints are employed to allow fluids to enter the production tubing. They can also be used to create a mud anchor. Perforated pup joints are included as goods subject to these investigations.

On March 23, 2010, the Tribunal excluded ‘pup joints’ as part of its finding in Inquiry No. NQ-2009-004 on Certain Oil Country Tubular Goods (OCTG). In that finding, the Tribunal stated:

“The Tribunal hereby excludes pup joints, seamless or welded, heat-treated or not heat-treated, in lengths of up to 3.66 m (12 feet), from its injury finding.” 7

Pup joints are manufactured in Canada by the Complainant using plain end tube as an input. For J55 grade pup joints, a length of J55 OCTG tubing is employed. For L80 grade pup joints, the input is an A-519 mechanical tube with the appropriate steel chemistry for L80 OCTG. The L80 input tube does not qualify for the API 5CT designation until it has been tested in accordance with API requirements. The Complainant performs the testing required.

The production process of the input pipe itself is virtually identical to that employed for OCTG tubing and casing. There are, however, significant subsequent costs associated with transforming the input tubing into pup joints including: cutting to length, end finishing, threading, and testing to meet the certification required.

For J55 grade pup joints, the Complainant produces an upset end by heating (upset forging) and butting to thicken the end of the pipe diameter for threading. J55 tubing is cut 8 inches longer than the required pup joint length to accommodate this process. In the case of L80 grade pup joints, the production process uses profiling rather than upset ends, and accordingly only 1/4 inch of additional length is needed to accommodate finishing. Profiling refers to machining the pipe towards the ends of the pipe so it is thicker at the far ends. This process is used instead of upsetting because upsetting a pipe with steel chemistry for an L80 grade would require the producer to heat-treat the pipe again.

Testing includes drift testing which is an assessment of the straightness within the hollow part of the tube, to ensure no bends or kinks exist after the pup joint was forged, and hydrostatic testing which assesses the pup joint"s ability to withstand internal pressure.

The Complainant, Alberta Oil Tool (AOT) of Dover Corporation, accounts for the major proportion of domestic production of like goods in Canada. The Complainant manufactures pup joints in Canada at its facilities in Edmonton, Alberta.

Dover Corporation (Canada) Limited (Dover) produces and markets a wide range of production service equipment solutions for the oil and gas industry. AOT is a division of Dover, and operates as part of the Norris Production Solutions business unit along with Norris Rods (USA). Norris was founded in 1882. AOT produces and sells its products under the Norris brand, including pup joints.

Among the products produced and sold by the AOT division of Dover are pup joints, sucker rods, drive rods, tubing and casing fittings, butterfly valves and controls.

Regarding the dumping investigation, information was requested from known and potential exporters, vendors and importers, concerning shipments of subject pup joints released into Canada during the Dumping POI of July 1, 2010 to June 30, 2011.

Regarding the subsidy investigation, information related to potential actionable subsidies was requested from known and potential exporters and the GOC concerning financial contributions made to exporters or producers of subject pup joints released into Canada during the Subsidy POI of January 1, 2010 to June 30, 2011.

In the current case, the Complainant requested that section 20 be applied in the determination of normal values due to the alleged existence of the conditions set forth in paragraph 20(1)(a) of SIMA. The Complainant provided information to support these allegations concerning the Chinese OCTG sector, which includes pup joints.

At the initiation of the investigation, the CBSA had sufficient evidence, supplied by the Complainant and from its own research and past investigation findings, to support the initiation of a section 20 inquiry to examine the extent of GOC involvement in pricing in the OCTG sector, which includes pup joints. The information indicated that Chinese prices in this sector have been influenced by various GOC industrial policies. Consequently, the CBSA sent section 20 RFIs to the GOC and all known Chinese OCTG producers and exporters to obtain information on the matter.

The OCTG sector, which includes pup joints, is the same sector that was examined in the CBSA"s investigations of certain Seamless Steel Casing (2008) and certain OCTG (2010). Each of those section 20 inquiries concluded that domestic prices in the OCTG sector in China are substantially determined by the GOC and that there is sufficient reason to believe that the domestic prices are not substantially the same as they would be in a competitive market.

The following is the CBSA"s analysis of the relevant factors that are present in the Chinese steel industry and which affect the OCTG sector, which includes pup joints.

The 2009 Steel Revitalization/Rescue Plan also applies to the OCTG sector in China, which includes pup joints. The GOC specifically directed one of the cooperating exporters in the OCTG(2010) investigation, which was one of the largest state-owned enterprise (SOE) producers, and possibly the largest seamless OCTG manufacturer, to reorganize with another company.14

The 12th Five-Year Plan also includes restrictions on steel capacity expansion. This plan further supports the initiatives in the NSP and the 2009 Steel Revitalization/Rescue Plan. The CBSA"s section 20 inquiry in the Seamless Steel Casing (2008) investigation confirmed that the GOC"s control of new or additional steel production capacity extended to the OCTG sector, which includes pup joints.22

As stated above, one GOC directive under the China Steel Pipe Industry 12th Five-Year Plan is to expand the development of OCTG products such as high collapse, anti-corrosion pipe.25 Chinese OCTG producers are not motivated solely by commercial interests, but must operate and be attentive to the GOC"s objectives, which may conflict with commercial interests. Based on the information on the record, the scope of the GOC"s macro-economic policies and measures have resulted in significant influences on pricing within the Chinese steel industry including the OCTG sector, which includes pup joints.

With the sole cooperating exporter/producer of pup joints being export-oriented, there is no information on the record for domestic selling prices of pup joints. In the absence of Chinese domestic prices for pup joints, the CBSA considers it reasonable to examine other goods in the OCTG sector such as casing and tubing, as pup joints are simply shorter lengths of OCTG casing and tubing.

The wide range and material nature of the GOC measures have resulted in significant influence on the Chinese steel industry including the OCTG sector, which includes pup joints. Based on the preceding, the President is of the opinion that:

During the final stage of the dumping investigation, the CBSA will continue the section 20 inquiry and further verify and analyze relevant information. The President may reaffirm his opinion that the conditions of section 20 exist in the OCTG sector, which includes pup joints, as part of the final phase of the investigation, or conclude that the determination of normal values may be made using domestic selling prices and costs in China.

For purposes of this preliminary determination, normal values could not be estimated on the basis of domestic selling prices in China or on the full cost of goods plus profit, because the President formed the opinion that the conditions of paragraph 20(1)(a) of SIMA exist in the OCTG sector, which includes pup joints, in China.

In calculating the weighted average estimated margin of dumping for the country, the overall estimated margins of dumping found in respect of each exporter are weighted according to each exporter"s volume of subject pup joints exported to Canada during the Dumping POI.

Based on the preceding, 100% of pup joints from China were dumped by an estimated weighted average margin of dumping of 125.7%, expressed as a percentage of the export price.

The estimated weighted average margin of dumping of certain pup joints from China is above 2% and is, therefore, not insignificant. As well, the volume of dumped goods from China is above 3%, and is, therefore, not negligible.

Hengshui Weijia is a producer and exporter of certain pup joints to Canada. The company was incorporated in August 2009 as a Sino-foreign joint venture.30 Hengshui Weijia is a limited liability company, which is privately held by a Chinese limited liability company, and a Canadian limited liability company, WestCan Oilfield Supply Ltd., which owns 49% of Hengshui Weijia.31

As previously explained, given the current absence of surrogate pricing or cost information, import pricing from other countries or any other pup joint pricing that would be usable for the purposes of a preliminary determination, normal values were estimated by advancing the export price of the goods by the estimated margin of dumping determined for the initiation of the investigation, which was calculated at 32.4%. The estimated margin of dumping for Hengshui Weijia is 32.4 %, expressed as a percentage of the export price.

In conducting its investigation, the CBSA sent a subsidy RFI to the GOC, as well as to the potential exporters located in China that had been identified through internal CBSA documentation. Information was requested in order to establish whether there had been financial contributions made by any level of government, including SOEs possessing, exercising or vested with government authority, and, if so, to establish if a benefit has been conferred on persons engaged in the production, manufacture, growth, processing, purchase, distribution, transportation, sale, export or import of certain pup joints; and whether any resulting subsidy was specific in nature. The GOC was also requested to forward the RFIs to all subordinate levels of government that had jurisdiction over the exporters. The exporters were requested to forward a portion of the RFI to their input suppliers, who were asked to respond to questions pertaining to their legal characterization as SOEs.

In summary, the GOC provided information concerning the amounts received by the identified exporters of pup joints to Canada for four subsidy programs. These programs are:

The GOC identified 18 subsidy programs that were not used by the exporters of pup joints during the POI and for the remainder of the 80 listed subsidy programs identified by the CBSA, the GOC either indicated that there was no such program, it had no information on the program or that the GOC disagreed with the CBSA on the nature of the subsidy.

Based on the information available to the President, on December 12, 2011, the President made preliminary determinations of dumping and subsidizing respecting certain pup joints originating in or exported from the People"s Republic of China, pursuant to subsection 38(1) of SIMA.

Pursuant to subsection 8(1) of SIMA, provisional duties, payable by the importer in Canada, will be applied to dumped and subsidized subject pup joints that are released during the provisional period commencing on the day the preliminary determinations are made, and ending on the earlier of the day on which the President causes the investigations to be terminated pursuant to subsection 41(1) or the day on which the Tribunal makes an order or finding. The imposition of provisional duties is needed to prevent the injury which, as per the Tribunal"s preliminary determination, was caused by the dumping and subsidizing of subject pup joints.

If the Tribunal makes a finding that the dumping has caused injury, retardation or is threatening to cause injury, anti-dumping duties in an amount equal to the margin of dumping will be levied, collected and paid on imports of subject pup joints.

If the Tribunal makes a finding that the subsidizing has caused injury, retardation or is threatening to cause injury, countervailing duties in the amount equal to the amount of subsidy on the imported goods will be levied, collected and paid on imports of subject pup joints.

Seamless pup joints with premium connections are available in API and exotic alloy grades. Premium ends are threaded by the manufacturer or authorized licensee.

Available with standard or special perforation spacings. Each joint has four rows of ⅜ inch holes drilled longitudinally along the tube. Optional patterns, hole size, and lengths furnished upon request.

Upset forging is a process by which a plain end blank is upset at each end to increase the cross section area. We have innovated upsetting by automating our handling table. This automated handling table not only helps us upset at different lengths safely, but also helps us to get pup joints to the highest degree of consistency and accuracy.

The hydro tests all of its pup joints. This non-destructive test uses water pressure and a pressure recorder to determine possible leaks. Our modernized tester can be adjusted to accommodate various lengths of pup joints, and test them at various pressures as required by API and customer specifications.

We has a custom & automated Full Body Ultrasonic Inspection system to inspect its tubing pup joints. We are the first in the industry to build and use a Full Body Ultrasonic Inspection for pup joints to ensure there are no defects on the external and internal surface longitudinal and transverse.

This inspection has greater accuracy than other non destructive tests, one reason is its high penetrating power to allow detection of defects deep in the pup joints. The Full Body UT also has high sensitivity which allows it to detect exceptionally small deficiencies. This inspection ensures that our customers receive the best quality pup joints on the market.

We also manufacture pup joints by profiling from heavy wall mechanical tubing. Profiling of pup joints are done in a high precision and tolerance CNC in order for us to achieve a high level of dimensional tolerances and surface finish.

The wet magnetic particle test is a non-destructive test that detects surface and shallow subsurface defects. Pup joints are inspected for longitudinal and transverse defects using this inspection method.

We have exclusively designed a line which heat treats each pup joint individually. This setup is versatile and dynamic, as it can be adjusted for various lengths of pup joints and modified accordingly. This gives us the advantage of catering to the needs of our customers extremely quickly. All pup joints are re-straightened after heat treat to ensure the highest quality.

A short casing or tubing that is used for handling the assemblies of production tubing is called Pup Joints. It is also used for spacing out full length tubing and casing strings. The npst pup joints are non-standard piping lengths that are available in two or five foot increments. However, customization is available on request. Their height can be adjusted of full length tubing and various kinds of drill pipes. The string pipes are assembled with the tubular goods having standard length and they are typically 31 feet in length. The length can be easily adjusted according to the exact requirements. They are quite dependent on the tubular goods with which they mate.
