Our tubing couplings are made from a variety of steel grades, including J55, K55, N80, N80-1,N80-Q,L80,P110, and more. We offer two types of casing couplings: NU and EU. Our threading process is efficiently completed using state-of-the-art numerically controlled lathes and imported molding cutters. This ensures the highest level of precision and guarantees that our couplings are interchangeable between different equipment.
To ensure quality control, we have implemented a comprehensive testing system equipped with specialized tools for measuring tape accuracy, inspecting pitch alignment, analyzing tooth depth consistency, and examining profile uniformity.
We stock an extensive range of sizes ranging from 2-3/8" to 20'' in
J55, K55,
N80,and P110 grades. Rest assured that all our couplings conform to
the stringent API Specifications 5CT standards - a testament to
their reliability and adherence to industry regulations.
