API 5CT Standard Casing and Tubing Coupling

API 5CT Standard Casing and Tubing Coupling The misalignment of the coupling will cause the axial movement and axial vibration of the pump shaft, thus opening the inner and outer sealing surfaces. As the solid particles pass through the sealing surface, the sealing life will be gradually shortened. This axial movement can also damage rolling bearings, such as thrust bearings. The fretting wear of the drive device (pin, key and matching groove, hole, set screw, etc.) installed on the shaft sleeve will lead to the loss of axial tracking (looseness) and damage of the seal ring. 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 Grade NUE…
