API 5CT Tubing and casing Coupling N80 Casing

API 5CT Tubing and casing Coupling N80 Casing Vibration will cause the movable ring set screw to loosen, resulting in loss of spring tension on the sealing surface and loss of torque transmission of rotating parts. Unbalance and misalignment of the coupling will cause higher radial alternating stress at the inner bearing, thus shortening its service life; High bearing wear will cause shaft vibration, which will affect the seal. The same force will also affect the driver, whether it is the motor or the turbine. The relevant forces caused by the imbalance and misalignment of the coupling will lead to the early failure of the motor with rolling bearings. Couplings are used to connect two joints of tubing coupling or casing pipe together. Couplings are short length of heavy wall pipe with the same threads on each end. EASTSUN manufactures tubing coupling and casing tubing coupling strictly comply with API 5CT latest standard. Size…
