api pup joint dimensions quotation

We manufacture pup joints in all sizes, grades, and thread profiles to meet any requirement. Our tubing pup joints are manufactured out of seamless tubing and machined or upset to final dimensions. All API casing and tubing pup joints are manufactured according to API Spec 5CT. Special requirements are available on request.

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.

Crossover pup joints are manufactured from seamless mechanical tube. As with all Crossover products, each piece is marked with a distinctive job number and heat number that is fully traceable. A complete range of sizes (1" to 4.5"), weights (standard or heavy wall), and grades (J-55, N-80, L-80, and P-110) are commonly available from stock in 2", 3", 4", 6", 10", and 12" lengths. Lengths up to 20" are available upon request.

Manufactured according to API Spec 5CT using prime API monogrammed, seamless oil country tubing. Optional diameters, lengths, weights, and grades are available upon request.

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.

Crossover, Inc. handles many types of API Couplings. As a rule, we stock enough of your common couplings which enable us to ship the same day if needed. We carry in stock J-55, L-80, N-80, and P-110. As for sizes, we carry 2 3/8”, 2 7/8” 3 ½”, 4 ½” tubing and some of the casing sizes up to 13 3/8”. Stock connections are EU 8 Rd., Nu 10 Rd., LTC, STC, and BTC. Our couplings are primarily of USA manufacture. If origin is not important, we can source other origins and sometimes beat the USA manufactured cost.

We manufacture a wide range of Crossover Couplings. Couplings are used to connect two sizes of pipes, or two different dissimilar threaded parts together. We offer special clearance couplings, special clearance couplings with bevels on both ends, and couplings with the API Seal Ring Modification.

Crossover swages are made from API grades of pipe and mechanical tubing. Rigid quality standards are maintained throughout the manufacturing process by frequent inspection and testing. Raw material quality is assured by our quality assurance program.

A blast joint is shorter in length than standard tubular joint. Built with a heavy wall pipe it is incorporated in the production string to facilitate production across any perforated interval and zone. Blast Joints are manufactured to the following specs connections, lengths, weights and material grade.

Crossover Blast Joints are heavy wall pin by box connectors used in tubing strings and are designed to minimize the effect of external erosive action caused by production fluids. Blast joints are located opposite the location of perforations in the production casing or just below the tubing hanger in sand frac designs. Crossover blast joints are manufactured from seamless mechanical tube in sizes ranging from 2 3/8” to 4 1/2” OD. Any length, grade of material, and threading is available at the customers request. Typical lengths are 10" and 20". Both API and Premium threads are available.

Crossover Flow Couplings are heavy wall box by box connectors used in tubing strings and are designed to minimize the effect of internal erosive action caused by production fluids. Flow couplings are located just above or below Landing Nipples, Safety Valves or Control Devices where turbulent flow problems are likely to occur. Crossover flow couplings are manufactured from seamless mechanical tube in sizes ranging from 2 3/8” to 4 1/2” OD. Any length, grade of material, and threading is available at the customers request. Typical lengths are 3" and 6". Both API and Premium threads are available.

Crossover Coarse Thread Tubing Safety Joint provides for emergency recovery of the major portion of the tubing string should it become necessary to abandon the equipment below. Precision left-hand threads facilitate the release of the joint by right-hand tubing rotation. Equipment requiring right-hand rotation should not be used below the Safety joint.

Crossover Straight-Pull/Shear-Out Safety Joint is used between packers in dual and triple completions and in selective completions using Hydrostatic Single-String Packers. It is also used when rotational releasing is not desired. When ran above the upper packer in a single-string completion, however, the shear value should be adjusted to compensate for any hydraulic conditions that exist when the string is landed, or that are created by well treating operations. They are available in keyed and non-keyed configurations.

Crossover can build these in any of the regular API Grades such as J-55, L-80, or P-110. These are usually only made going up or down one size in either direction such as ¾” to 1” or 1 ½” to 2”.

A saver sub falls under the drill string accessory tool category and a short pipe that is replaceable and expendable without a major investment. This accessory protects the Kelly or topdrive component threads and those components represent a significant capital cost and considerable downtime when replaced. Saver sub are manufactured to the following specs connections, lengths, weights and material grade.

Crossover rotary shoes are manufactured from specially tempered steel to provide the ultimate in toughness and durability. They are used to cut a clearance between the fish and the wall of the well bore. Each shoe is tailored to fit a particular downhole need and normally is run on the bottom of one or more joints of washover pipe. Shoe design is dictated by whether it cuts on the bottom, on the OD, on the ID, or any combination of these. When hole sizes permit, additional clearances can be cut using side ribs, thus providing greater circulation.

OCPL offers a wide range of OCTG Casing Pup Joints, with both API and premium threads, manufactured at our select API spec. 5CT compliant steel mills.

If you’re looking for pup joints, we provide tubing and casing pup joints of all sizes, grades, and thread profiles to meet any requirements set by our customers. All API casing and tubing pup joints are manufactured according to API Spec 5CT.

Tube Supply stocks a variety of sizes in tubular form in these grade categories. All grades are in compliance with API 5CT mechanical and impact testing expectations, including ultrasonic testing.

API Coupling refers to the steel couplings that used in connecting casing pipe and tubing. Also known by OCTG coupling, it is usually manufactured in seamless type, material grade same with the pipe body (API 5CT K55/J55, N80, L80, P110 etc), same PSL or providing higher grades than requested. Same heat treatment also applicable, except there is an special requirements.

With this purpose, API 5CT standard coupling plays an important feature in connecting casing and tubing line pipes. On the contrary, the biggest different with general steel pipe coupling is: API coupling manufacturing processes is more rigorous, requires a precisely control in the different processes as blew listed.

As we told, one of the important figure of API coupling, that it shall be made of seamless, another is the same grade as the casing or tubing pipe body, and these materials are used for manufacturing the blank coupling.

Coupling should be processed from coupling blanks or from coupling stock, including manufactured in hot forging. (Except Grade C110 and Q125 couplings shall not be in hot forging. These two grades material are typically different from other grades, so if you are purchasing couplings in this grades, should pay more attention to read regulations in API 5CT spec.)

There are several types covered in API 5CT standard for coupling specifications, classified in regular couplings, special clearance couplings, combination couplings, reducing couplings, seal ring couplings, and special bevel tubing regular couplings.

Regular couplings diameters complied with API 5CT Tables C.32 to C.35 or Tables E.32 to E.35. Coupling bearing contact face inside and outside edges shall be rounded or broken, but shall not significantly reduce the width of the bearing face (dimension b), since less thickness will not be safe to support the pipe weight. The ends of couplings shall be faced exactly at right angles to the axis.

Special-clearance coupling dimensions and tolerances shall comply to as given in Tables C.33 and C.35 or Tables E.33 and E.35 and as shown on Figures D.3 and D.5. Color identification see clause 11.

Casing coupling is for the dimensions more than 4 1/2 inch. Differently than tubing coupling is, casing coupling normally does not need to be thickened (Non-upset), which means no upset casing coupling, so it has following types:

The oil casing coupling is a necessary piece used to connect the two casing. The coupling manufacturing method is the same as seamless pipe. The steel pipe ends with internal thread to connect with the upper and lower casing. In order to ensure the joint tightness, the precision of screw thread is strictly required.

API Threads is for the threads manufactured and inspected under API 5B. Couplings shall not be expanded to provide required threads taper under API specifications.

(NOTE Couplings with API threads may not have a leak resistance as high as the internal yield pressure of the pipe body, due to inadequate bearing pressure between the coupling and pin.)

API 5B covers dimensions, tolerances, and marking for API threads and the gauges that control the acceptance criteria for the threads. It includes thread element gauges, instruments, and requirements for the inspection of threads for line pipe, casing and tubing (round threads), and buttress casing connections. Thread dimensions shown without specifications (or shown as NA) are not subject to inspection of diameter, ovality, and addendum. Thread dimensions shown without tolerances are related to the basis for connection design and are not subject to measurement to determine acceptance of product.

The inspection requirements include measurements of standoff, diameter, ovality, addendum, taper, lead, height, and thread angel. It shall be noted that these specification are only applicable to threads quantity less or equal to 11 1/2 per inch (which 0.45 or less turns per mm). Ring and plug gauges are designed to measure the functional size of an internal or external thread. Individual thread elements listed in API 5B are measured with one or more specific instruments.

API casing and tubing coupling dimension ranges from OD 1.05 inch to 20 inch (26.7 mm to 508 mm), wall thickness normally ranges from 0.16 inch to 1 inch (4.2 mm to 22 mm).

For Group 1, 2 and 3, Unless specified in the purchase agreement, coupling dimensions and tolerances shall be complied to API 5CT table C.32 to C.35 or tables E.32 to E.35.

For Group 4: Not only internal machining could be done to Coupling, external machining also could be done to. Except API couplings and threads shall comply to C.32 and C.33, or E.32 and E.33, in case other connections couplings or threads (Premium connection), couplings sizes shall be specified in the agreement.

According to API 5CT specification, the internal and external surface of coupling shall not have folding, cracks, separation, scaling and other defects.

Octal supplies API couplings for casing and tubing connections, feel free to contact us for any of the request refer to the API or premium connections.

Besides casing and tubing, it also includes pup joints, coupling stock, coupling material, and accessory materials, and establishes requirements for three product specification levels (PSL-1, PSL-2, and PSL-3). The requirements for PSL-1 are the basis of this standard.

According to API 5CT standard, steel material used for making the pipe billet supplied shall be grain refining treatment. This steel shall contain one or more grain refining elements, such as a certain amount of aluminum, niobium, vanadium or titanium, so that the austenite grains of the steel Grain refinement.

Heat treatment methods for API 5CT casing and tubing is an important factor to differ each grade. Products requiring heat treatment shall be subjected to full body and full length heat treatment. The heat-treated upsetting product should be heat treated full body, full length after upsetting.

Product threading, gauging practice and thread inspection shall be in accordance with API Spec 5B. The product end shall not be hammered, but may be slightly shaped to meet the requirements of thread machining. For steel grades of C90 and higher strength, such forming shall only be carried out with the consent of the purchaser.
