The Pup Joint is a short‑length tubular component that conforms to API 5CT standards and is manufactured from carbon steel grades J55 or L80. It is supplied as a seamless coupling with threaded connections, allowing precise length adjustments in casing or tubing strings during drilling and completion operations. The joint’s design focuses on reliability under high‑pressure downhole conditions, and it is presented as a core OCTG product for oilfield and geothermal projects. The supplier lists the product for export from Dongying, China, targeting drilling contractors and equipment distributors.
In the OCTG market, API 5CT‑compliant joints typically offer outer diameters of 4.5, 6.5 or 9.5 inches with wall‑thicknesses that meet the required pressure ratings for each size. For J55 grade the minimum tensile strength is around 70 000 psi, while L80 provides roughly 80 000 psi, both within the standard tolerances for API‑rated pipe. Thread specifications follow the API external thread profile, usually 11‑13 threads per inch, and length is commonly 1 metre to facilitate handling in confined wellbore spaces. These dimensions and mechanical properties are standard across manufacturers of pup joints.
Primary users include drilling contractors, oil‑field service firms and water‑well developers who need to shorten or extend the overall casing string without compromising structural integrity. The product is shipped FOB from the Dongying port, and the supplier notes flexible minimum order quantities, though exact figures are not disclosed. Prospective buyers should confirm lead‑time, payment terms and any required certifications such as ISO 9001 before finalising a purchase.

Importers should first request the mill test report and verify that the steel grade, tensile strength and dimensional tolerances match the API 5CT requirements for the intended well design. Confirm that the joint’s outer diameter and wall thickness are suitable for the existing casing program before placing an order.
Shipping is normally arranged on an FOB basis from the Dongying port. Buyers need to clarify the expected lead time, which can vary with order size and steel availability, and agree on Incoterms such as FOB or CIF. Payment terms are typically telegraphic transfer or a letter of credit, and these should be confirmed in the purchase agreement.
A third‑party inspection can be scheduled to check thread integrity, dimensional accuracy and surface condition prior to loading. Request a certificate of analysis and any applicable ISO or SGS certificates to ensure compliance with quality standards. Prepare the appropriate HS code for steel pipe fittings and arrange customs documentation in advance to minimise clearance delays.
