Product Description of Tubing Couplings

Our tubing couplings are manufactured using various steel grades such as J55, K55, N80, N80-1,N80-Q,L80,P110, and more. For casing couplings, we offer two types: NU and EU. With the use of advanced numerically controlled lathes and imported molding cutters, our threading process is completed in a single operation to ensure consistent quality and interchangeability.

At our facility, we have comprehensive testing capabilities that include tape measurement, pitch inspection, tooth depth analysis, and profile examination. These tests are conducted using dedicated equipment specifically designed for thread assessment.

We provide a wide range of sizes from 2-3/8" to 20'' in J55, K55,
N80,and P110 grades. All of our couplings comply with the API Specifications 5CT standards to guarantee their reliability and performance.
