Api Threading Oil Pipe Casing Tubing Coupling
Api Threading Oil Pipe Casing Tubing Coupling from Tianjin Dalipu connects two oil tubing or casing pipes in drilling and production operations. The couplings are manufactured to API 5CT standards and offered in carbon or alloy steel across API grades J55, K55, N80, L80, and P110, with thread configurations including EUE, NUE, STC, LTC, and BTC to ensure leak-proof tubular assembly. Specification range covers outer diameters from 2-3/8" to 20", with wall thicknesses between 4.24 mm and 16.13 mm.
Material grades align with API 5CT requirements, where P110 offers the highest yield strength for demanding downhole conditions. Color-coded thread compounds (red, green, white) indicate specific lubrication and sealing properties, with non-destructive testing (NDT) applied per API 5CT and 5B rules. Typical industry practice includes hydrostatic testing and dimensional inspections to verify thread integrity and pressure resistance.
These couplings are used in onshore and offshore oilfields to maintain wellbore stability and prevent fluid migration between formations. Buyers typically source by metric ton, with P110-grade couplings commanding premium rates due to their enhanced mechanical properties. Common applications include vertical, directional, and horizontal wells where reliable tubular connections are critical to operational safety and efficiency.

Sourcing Api Threading Oil Pipe Casing Tubing Coupling from Tianjin Dalipu Oil Country Tubular Goods Co., Ltd - China Import Guide
Before ordering, verify the API grade and thread type compatibility with your existing tubulars. Confirm that the supplier can provide third-party inspection reports and mill test certificates for the chosen grade, as these are critical for compliance with oilfield standards.
Discuss logistics details such as lead time, which can vary based on diameter and grade availability. Clarify Incoterms (e.g., FOB Tianjin) and payment terms, as these impact total landed cost. Packaging should meet API 5CT requirements for protection against corrosion and damage during transit.
Inspect the couplings upon arrival for dimensional accuracy, thread integrity, and surface finish. Request copies of NDT reports and hydrostatic test results. Ensure documentation includes heat numbers, grade markings, and traceability to the original mill for quality assurance.
