Product Details

The standard for couplings on tubing is to implement API5CT and API 5B standards. API5CT includes the dimensions of tubing and casing couplings, physical and chemical properties of steel grade, P110S anti-sulfur tubing couplings, and the parameters of coupling threads in API5B. . The coupling of the coupling is almost controlled according to the withholding torque, and there is also a control according to the value of J. The coupling is threaded, but the specified torque must be reached. The coupling of the ladder-type threaded sleeve must be screwed to the triangle symbol. The bottom edge.
