Integral pup joints are short spools that provide precise spacing and alignment when connecting flanges, valves and fittings in high‑pressure piping systems. They are offered in carbon steel as well as stainless‑steel grades 304 and 316L, giving buyers options for corrosion‑resistant service. The joints are available in a variety of schedules and are rated to withstand pressures up to 15,000 psi, meeting the demands of oil, gas and petrochemical installations.
Typical industry practice supplies pup joints with lengths between 6 and 12 inches and nominal diameters from 2 to 6 inches, conforming to standard schedule 40 or 80 dimensions. The components are usually delivered with flanged ends that eliminate the need for welding, reducing the risk of leak paths. Both ISO and API standards are referenced for material composition, dimensional tolerances and pressure testing, ensuring reliable performance in harsh environments.
Primary users include refinery EPC contractors, offshore platform engineers and industrial plant maintenance teams that require reliable short‑run connections. The supplier states that flexible minimum order quantities are possible and that the items are packaged for international shipping under FOB or CIF conditions. Prospective buyers should confirm the exact dimensions, material grade and required certifications before finalising the purchase.

Importers should first request the mill test report, material certification and dimensional inspection sheet to ensure the pup joints meet the required schedule, diameter and pressure specifications. Verifying the coating type and internal finish is also advisable for projects involving corrosive fluids.
Shipping is normally arranged from a Chinese port such as Qingdao under FOB or CIF terms, although the exact departure point should be confirmed with the supplier. Lead‑times are not published, so a clear delivery schedule and agreed payment milestones - typically T/T in advance or L/C at sight - must be established before order confirmation.
A third‑party inspection prior to loading is recommended, focusing on flange alignment, wall‑thickness measurement and pressure‑test results. Ensure that the API pressure‑test certificate, coating verification report and full packing list accompany the commercial invoice to streamline customs clearance and downstream quality acceptance.
