Product Details
Description
A pup joint is a 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 Joint
Tubing pup joints are designed and manufactured as per API 5CT to be used be adjust the height of tubings, and tubing pup joints are made of seamless steel tubings. Material grade of tubing pup joint can be available 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 joints are often offered in 2ft, 3ft, 4ft, 6ft, 8ft, 10ft, and 12ft, length of pup joints for special purposes can be available as per order. Tubing pup joints are machined with interchangeable Pin & Box thread on two ends or other configurations, one end is equipped with coupling, and another end is protected with a closed-end thread protector. The nominal weight of the tubing pup joint is the same as the 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. Finished tubing pup joints are often packed by steel belts in bundles, and then fixed in steel rack for easy transportation.
Casing pup joint
Casing pup joints are designed and manufactured as per API 5CT to be used be adjust the height of casings, and casing pup joints are made of seamless steel casings. Material grade of casing pup joint can be available in J55, K55, N80, L80 or P110, sizes of casing pup joint range from 4½¡± to 13⅜¡±, thread of pup joint can be 8RD, 10RD or BTC, 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. Casing pup joints are machined with interchangeable Pin & Box thread on two ends or other configurations, one end is equipped with coupling, and another end is protected with a closed-end thread protector. The nominal weight of the casing pup joint is the same as the casing. Casing pup joints are internally and externally hydrostatic tested with tension and compression loads, torque tested, and electromagnetically inspected, pup joint is full-body drift and straightness visually inspected, and phosphate and dye-penetrant inspected. and finally painted by machine to ensure excellent appearance. Finished casing pup joints are often packed by steel belts in bundles and then fixed in steel racks for easy transportation.

API Spec 5CT – This Standard specifies the technical delivery conditions for steel pipes (casing, tubing and pup joints), coupling stock, coupling material and accessory material and establishes requirements for three Product Specification Levels (PSL-1, PSL-2, PSL-3). The requirements for PSL-1 are the basis of this Standard. The requirements that define different levels of standard technical requirements for PSL-2 and PSL-3, for all Grades except H-40, L-80 9Cr and C110, are contained in Annex H.
