The Derun Casing & Tubing Pup Joint is a short tubular section used to adjust the length of casing or tubing strings during well construction. It is manufactured to API 5CT standards and is available in J55, K55, N80, L80, and P110 steel grades. The standard outer diameter is 4-1/2 inches, with threaded ends in LTC or STC configurations to ensure compatibility with industry-standard connections.
These pup joints are made from seamless or electric resistance welded (ERW) steel, depending on grade. Higher grades like L80 and P110 undergo heat treatment to achieve specified yield and tensile strengths. Surface finish is typically plain or with protective oil coating. The product is not coated for corrosion resistance unless specified; buyers requiring H2S resistance must request NACE MR0175 compliance.
Operators in the Middle East, Central Asia, and North American shale regions use these pup joints to optimize casing string alignment and reduce non-productive time. The product is shipped in bulk with protective end caps and marked with grade, heat number, and API monogram. Trade terms are typically FOB Tianjin or CIF to major ports. Minimum order quantities are not stated but are usually 10 to 20 pieces per shipment.

Before ordering, confirm the steel grade, thread type, and heat treatment method with the supplier. Request a copy of the mill test report for each batch, including yield strength, tensile strength, and hardness values. Verify that the product is marked with the API monogram and heat number. Do not accept products without traceable documentation.
Confirm the Incoterms - FOB Tianjin is likely, but clarify whether the supplier arranges export customs clearance. Lead time is not stated; request a written production schedule. Payment terms are not specified, but T/T in advance or L/C at sight are common. Ensure the contract includes penalties for non-conforming material and delivery delays.
Inspect incoming shipments for thread damage, surface defects, and correct marking. Use a thread gauge to verify LTC or STC compliance. Retain a sample from each batch for future reference. Conduct a hardness test on a sample if the grade is L80 or P110. Maintain a log of supplier performance to evaluate reliability over time.
