pup joint fabrication made in china

A pup joint is Casing, Pipe or Tubing shorter in length than a standard tubular string. This allows for the adjustment and installation of tools and various tubular components when placement downhole is critical for a specific project. A Spacer Pipe is another reference used to identify pup joints. Pup joint features consist of connections, lengths, weights and material grade.

Tubing pup joints are desiged and manufactured as per API 5CT to be used be adjust height of tubings, and tubing pup joints are made of seamless steel tubings. Material grade of tubing pup joint can be avalialbe in J55, K55, N80, L80 or P110, sizes of tubing pup joint range from 2⅜¡± to 4½¡±, thread of pup joint can be 8RD, 10RD or BTC, and end connection types can be NUE and EUE. length of tubing pup joint are often offered in 2ft, 3ft, 4ft, 6ft, 8ft, 10ft and 12ft, length of pup joint for special purpose can be available as per order. Tubing pup joints are machined with interchangeable Pin & Box thread on two ends or other configuration, one end is equipped with coupling, and another end is protected with closed end thread protector. Nominal weight of tubing pup joint is the same as tubing. Tubing pup joints are internally and externally hydrostatic tested with tension and compression loads, and torque tested, electromagnetically inspected, pup joint is full-body drift and straightness visual inspected, and phosphated and dye-penetrant inspected. and finally painted by machine to ensure excellenct appearance.

[69]As mentioned earlier, four parties provided responses to the CBSA’s ERQ: Canadian producers AOT and Tenaris Canada and related importer and exporter WestCan and Weijia. In addition to ERQ responses, AOT, WestCan and Weijia submitted case briefs. All four parties made representations that dumping of pup joints from China is likely to continue or resume should the CITT rescind its finding.

[71]A narrower picture of the steel market, the seamless pipe market - of which pup joints are a small subset - offers a similar view. According to data from China’s National Bureau of Statistics, the country’s seamless pipe output increased to a record yearly high of 29.63 million metric tons in 2013 due in part to newly commissioned capacity. CISA affiliated China Metallurgical News (CMN) predicted that, due to oversupply and lukewarm domestic demand, the seamless pipe industry would likely remain under downward pressure in 2014. CMN also warned that the ramp-up in China’s seamless pipe production was likely to continue and that the overcapacity could cause the surplus to worsen in the coming years.

[74]Specific information on production volumes and production capacities of pup joint producers in China is difficult to obtain. The reason for this is that pup joints are a very small subset of a much larger group of products called OCTG, comprised primarily of casing, tubing and drill pipes. Due to the small quantities of pup joints produced and the correspondingly small revenues generated from their sales, many companies do not track their production independently. OCTG producers, who are primarily concerned with producing and selling full length casing and tubing products, may simply merge pup joint production data with that of either casing or tubing since pup joints are often considered smaller pieces of casing and tubing. Despite the difficulties encountered in finding accurate production data on pup joints, either from producers themselves or from trade publications, there is sufficient information on the CBSA’s record pertaining to the broader category of OCTG products as well as information pertaining to a limited number of pup joint producers in China.

[76]OCTG producers in China who also produce pup joints include such companies as: Shandong Molong Petroleum Machinery, which boasts production capacity of 650,000 mt/y;

[80]In Canada, there are currently 11 different steel products from China that are subject to anti dumping duty, not including pup joints. Of note are many tubular products such as carbon steel welded pipe and piling pipe and, more specifically, line pipe, OCTG and seamless casing.

[81]As stated above, pup joints from China are not only subject to a finding in Canada but are also subject to an anti-dumping duty order in the U.S. by virtue of being included under the product definition of ‘oil country tubular goods from China’. In May 2015, the U.S. International Trade Commission extended anti-dumping duty orders on OCTG from China for a further five years. Based on the fact that the North American market is one of the largest OCTG markets in the world, and the fact that the Canadian and American markets are highly integrated with many of the same players, there is a distinct possibility that pup joints from China will be diverted from the U.S. market to Canada to be sold at unrestricted prices should the finding be rescinded.

[82]In the CBSA’s original dumping investigation of pup joints from China, which was initiated in 2011, Weijia was the only exporter to participate. Similarly, Weijia was the only exporter of pup joints to participate in the CBSA’s re-investigation of these goods in 2015. In both instances Weijia received a ruling letter from the CBSA outlining how the company would receive normal values on a monthly basis. The normal values would be based in part on the selling prices of tubing product sold in the U.S. and tracked by the trade publication Pipe Logix. It is noteworthy that Weijia has been able to sell to WestCan, its related importer in Canada, during the POR while imports of subject pup joints from other exporters in China have ceased. The lack of cooperation of other exporters in the re-investigation and the fact that all other exporters have vacated the Canadian market while Weijia has remained is a telling indication of the inability of other exporters in China to compete in Canada at non dumped prices.

[83]Also telling are the comments made by certain pup joint producers in China and obtained by AOT in response to its request for price quotations. The comments indicate that Canadian customers stopped purchasing pup joints once anti-dumping and countervailing duties were put in place in December 2011.

[84]In order to determine at what price levels pup joints from China might re enter the Canadian market absent the finding, WestCan procured a number of quotes from potential suppliers in that country.

[85]The likelihood of continued or resumed dumping of pup joints from China must be examined in context of what is happening in Canada’s oil and gas industry, in which OCTG products play an integral role. In 2014 oil prices peaked at around $US115/barrel, fell to $US27/barrel in January 2016 and have remained under $US50/barrel ever since. The rapid declines in oil prices in 2015 and 2016, along with continued weakness in gas, caused a dramatic decline in drilling activity in Canada. In 2013 and 2014, 11,000 wells were drilled in North America but drilling declined to 5,300 wells in 2015 and it is anticipated that only 3,400 wells will be drilled in 2016.

[86]Based on information on the record demonstrating the significant production capabilities of OCTG and pup joint producers in China and a slowing demand for these products in that country; anti-dumping measures being imposed by Canada and other countries on the same or closely-related tubular products from China; and the inability of exporters, save one, to sell pup joints in Canada at non-dumped prices, the CBSA determined that the expiry of the finding is likely to result in the continuation or resumption of dumping into Canada of certain pup joints originating in or exported from China.

The items to be imported are referred to as pup joints and C&C hoses. A pup joint is a seamless cold-drawn alloy steel pipe that is threaded on one end and fitted on the other end with a wing union nut. The function of the pup joint is to connect two pieces of high-pressure equipment. A C&C hose is comprised of two pieces of seamless cold-drawn alloy steel piping connected by a wing union nut and swivel joints. Though in the form of a loop when in the closed position, the nut can be undone and the pipe can be rotated to the desired direction. Like the pup joint, the C&C hose is used for connecting high-pressure equipment. In addition, this loop can be used as a means of connecting either two pieces of pipe or two valves together in high-pressure applications.

The applicable subheading for the pup joints will be 7304.51.5060, Harmonized Tariff Schedule of the United States (HTSUS), which provides for tubes, pipes and hollow profiles, seamless, of iron (other than cast iron) or steel, other, of circular cross-section, of other alloy steel, cold-drawn or cold-rolled (cold-reduced), other, other, other. The rate of duty will be free.

In your letter, you suggest classifiying the C&C (cementing and circulating) hose as a pipe/tube under subheading 7304.51.5060. This hose is not merely lengths of pipe with fittings attached. Rather, this fabrication is made up into a specific identifiable article which can be folded up for transportation and storage. As such, it would be excluded from classification under any of the pipe/tube headings in Chapter 73.
