Product Introduction

Pup joint is kind of seamless pipe with non-standard length to adjust the length of tubular strings to its exact requirement. API 5CT casing and tubing pup joint are produced according to API SPEC 5CT standard. Beyond the standard of oil casing pipe is called pup joint, the main oil casing pup joint material: J55, K55, N80, L80, C90, T95 and P110. We can supply pup joint with good quality.
