13-3/8 BC K55 Casing Coupling
Tianjin Dalipu Oil Country Tubular Goods Co., Ltd manufactures this 13-3/8 inch BC (Buttress Casing) coupling in K55 steel grade, designed for connecting large-diameter casing strings in oil and gas wells. The coupling is produced to API 5CT specifications, which is the standard for casing and tubing used in the petroleum industry. Its primary function is to provide a pressure-tight, reliable joint between lengths of 13-3/8 inch casing pipe, which is a common size for surface or intermediate casing in many well designs.
K55 is a standard API grade with a minimum yield strength of 55,000 psi, offering a balance of strength and cost-effectiveness for many conventional drilling environments. The Buttress Casing thread form is engineered to provide good tensile strength and resistance to cross-threading during installation. Typical material specifications include controlled chemistry for weldability and toughness, with standard surface treatments applied to the threads for corrosion resistance during storage and use.
This coupling is sourced by operators and drilling contractors for both onshore and offshore well construction projects. Bulk procurement is common for rig-site inventory or integrated drilling campaigns. Tianjin Dalipu's listing mentions competitive shipping terms including FOB and CIF, but specific pricing, minimum order quantities, and current lead times must be negotiated directly with the supplier based on order volume and destination.

Sourcing 13-3/8 BC K55 Casing Coupling from Tianjin Dalipu Oil Country Tubular Goods Co., Ltd - China Import Guide
When sourcing 13-3/8 BC K55 couplings from Tianjin Dalipu, begin by requesting the official API 5CT license number and the most recent Mill Test Certificates for the material grade. Verify that the certificate's heat number and batch details align with your order. For critical well applications, consider a pre-shipment inspection at the factory by a third-party agency to witness dimensional checks and hardness testing on a random sample.
Negotiate clear commercial and logistics terms in the contract. Specify the exact shipping terms (FOB Tianjin, CIF to your port, etc.), the payment method and schedule, and the guaranteed manufacturing lead time. For large orders, confirm the production capacity to meet your timeline. Ensure the contract includes penalties for late delivery and clearly defines the procedure for handling non-conforming goods upon arrival.
Implement a robust receiving inspection protocol at your warehouse or rig site. Check every coupling for visible damage, verify thread protectors are secure, and confirm the markings (grade, size, heat number) match the documentation. For a high-value, safety-critical component like casing couplings, investing in a sample dimensional verification using thread gauges is a prudent quality assurance step before putting the product into inventory or service.
