The 13-3/8 L80 BTC Collar is a critical downhole component used in oil and gas well casing and tubing strings. Manufactured by Tianjin Dalipu Oil Country Tubular Goods Co., Ltd in China, this collar is designed to connect sections of 13-3/8 inch casing pipe. It is produced to the API 5CT specification, which governs the material grade (L80) and thread type (BTC, or Buttress Thread Casing).
L80 grade steel is a standard material for this application, offering a yield strength of 80,000 psi and good resistance to sulfide stress cracking, which is important in sour well environments. The BTC thread profile provides a reliable, gas-tight seal and is designed for high tensile and compressive loads. Typical dimensional specifications for a 13-3/8 inch collar include an outer diameter of approximately 14.375 inches and a length that varies based on the manufacturer's design.
This component is procured by drilling contractors, oilfield service companies, and operators for well construction and completion operations. Sourcing from a Chinese manufacturer like Tianjin Dalipu offers a cost-competitive option. Buyers should verify the supplier's API monogram license, request material test reports (MTRs), and confirm lead times and shipping terms (e.g., FOB Tianjin) to ensure the product meets project specifications and delivery schedules.

Before ordering 13-3/8 L80 BTC collars from China, your first step is to verify the supplier's API 5CT license. Request a copy of their current API certificate and confirm it covers the manufacture of casing collars. This is a non-negotiable quality and safety requirement for most oil and gas operators.
Clearly define your technical requirements in the purchase order. Specify the exact API 5CT edition, the L80 grade, and the BTC thread profile. Request that the supplier provides a pre-shipment inspection (PSI) plan, which should include dimensional checks, visual inspection, and thread gauging. Consider hiring a third-party inspection agency to witness the PSI at the factory in Tianjin.
For logistics, agree on Incoterms such as FOB Tianjin or CIF your destination port. Get a detailed packing list and shipping marks specification. Clarify the documentation required for customs clearance, which typically includes the commercial invoice, packing list, bill of lading, MTRs, and the API certificate. Establish a clear communication protocol for production updates and shipment tracking to manage your project timeline effectively.
