A pup joint is a specialized, non-standard length of pipe used to fine-tune the overall length of tubular strings in oil and gas operations. These joints are essential for ensuring precise alignment and connection integrity during drilling, casing, or tubing runs. Pup joints are commonly manufactured to meet industry standards such as API Spec 5CT, using high-quality seamless oil country tubing that carries the official API monogram.
API casing and tubing pup joints are produced from premium materials, ensuring durability and performance under demanding downhole conditions. In addition to standard options, premium pup joints are available with advanced connections and can be made from both API-standard and exotic alloy grades to suit specific application requirements.
