The Pup Joint is a short‑section pressure‑containing pipe component used in offshore and onshore drilling riser systems. It is manufactured from Carbon Steel API 5CT Grade L80 or AISI 4130, with bore sizes ranging from 1‑13/16" to 21‑1/04" as listed in the source data. Working pressure ratings cover 3 000 psi to 20 000 psi and connections are offered in API 6A flange, API 16A clamp or WECO union formats. The component complies with API Spec 6A and NACE MR0175 standards.
The joint is forged from high‑strength alloy AISI 4130 and may be supplied in material classes AA through FF, providing options for sour service environments. Typical industry practice includes a heat‑treatment process to achieve 60 K or 75 K tensile strength, and optional stainless‑steel 316L or Inconel 625 ring grooves for corrosion‑resistant applications. Paint finishes are available in red, blue or custom colours, and the design minimises overall length while maintaining clearance for wrench access.
Pup Joints are purchased by oilfield service contractors and drilling engineers to connect choke and kill manifolds, or to adjust spacing between wellhead components. Suppliers can fabricate custom overall lengths and provide tap‑end studs and nuts where required. Buyers should confirm minimum order quantities, Incoterms and payment terms directly with the supplier, as these details are not disclosed in the listing.
