Pup Joints

Typical Lengths: 1, 2, 3, 4, 6, 8, 10, 12 ft

Unlike casing pup joint, tubing pup joint enable precise adjustment of production tubing strings. Their application focuses on adjusting fluid flow properties rather than protecting the oil and tubing joints allow equipment such as gas lift mandrels or packers to be lowered into pre-planned well locations. Minor length adjustments help assemble tubing of optimal size. Extenders can also fill gaps by removing damaged joints. Corrosion-resistant alloys such as J55S and [80T are suitable for tubing joint manufacturing. Strong flush connections prevent tubing from sticking while running in the well. High-quality seals and precision threads maintain the integrity of critical production tubing.

The main materials of oil casing short sections are J55, K55, N80, L80, C90, T95, and P110. Hot rolling process round tube billet → heating → perforation → three-roller oblique rolling, continuous rolling or extrusion → tube removal → sizing (or reducing diameter) → cooling → straightening → water pressure test (or flaw detection) → marking → storage; cold drawing (rolling) seamless steel tube round tube billet → heating → perforation → heading → annealing → pickling → oiling (copper plating) → multi-pass cold drawing (cold rolling) → billet tube → heat treatment → straightening → water pressure test (flaw detection) → marking → storage.

Pup joints play an important role in drilling, completion and workover operations. The three main applications are casing strings, production tubing and oil country tubular goods (OCTG). Understanding typical uses helps in making the right selection to optimize structure and function.In our oil production, the use of oil pipe pup joint is very, very important for oil. In fact, generally speaking, our pup joint is just a very important industrial pipeline connection accessory. Our oil short connection application is mainly applied to the casing inside the oil production equipment. Refining oil is not an easy task. There must be no mistakes in the mining process. Because oil work is different from other jobs, it is a job closely related to the lives of all of us, an extremely dangerous and difficult job. Once there is a problem in oil extraction, it is by no means a small problem. The economic loss is immeasurable. And our oil pipe pup joint is a small but important small accessory in oil extraction to prevent any economic loss.

Baowei-Steel offers high-quality pup joints designed to meet the rigorous demands of oil extraction. Our pup joints undergo hydrostatic testing, torque testing, and electromagnetic inspection to ensure reliability and durability. Whether used for casing strings or production tubing, Baowei-Steel's pup joints effectively prevent potential risks, avoiding costly losses. Choosing BAOWI Steel means securing your oil production with reliable support, ensuring safety and success.
