ESASTSUN OILFIELD EQUIPMENT MANUFACTURING (CAMBODIA) CO., LTD
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. The steel coupling is mainly used to connect oil pipes in pil drilling. This product can be used to connect the shafts of units that are manufactured separately. It can fit the misalignment of the shafts or introduce mechanical flexibility. The pipe coupling is capable of reducing the transmission of shock losds from one shaft to another. It can also introduce protecyion against overloads. The steel coupling can be used to alter vibration characteristics of rotating units
Aluminum Reducing Coupling API Coupling The coupling is also called coupling, coupling and back wheel. The coupling is the main component connecting the pump shaft and the prime mover and transmitting power. Generally, flexible coupling is used for pump coupling to compensate the relative displacement of pump shaft and motor shaft, reduce the requirements for accurate alignment of coupling installation, mitigate impact, change the natural vibration frequency of shaft system, and avoid hazardous...

Good Price API 5CT eue tubing coupling Coupling, also known as coupling, is a mechanical component that is used to firmly connect the driving shaft and driven shaft in different mechanisms to rotate together and transmit motion and torque. Sometimes, it is also used to connect the shaft with other parts (such as gear, pulley, etc.). Double diaphragm coupling: made of aviation materials, high torque rigidity and high sensitivity, applicable to all motors. Single diaphragm coupling: all stainless...

API Casing/Tubing/Coupling/Line Pipe The misalignment of the coupling will cause radial force, resulting in bending or deflection of the shaft during each rotation, thus affecting the fitting of the mechanical sealing surface inside the pump. The sealing surface is forced to open because the sealing spring is difficult to react to the bending of each shaft and higher vibration frequency in time. Rupture of the lubricant film between the sealing surfaces will cause wear and erosion of the...
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...
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...
Customize x-over a105 3 1/2 eue tubing coupling price The destructive force can be transmitted through traditional dry elastic metal coupling and lubricated coupling (such as gear or spring coupling). However, if modern permanent magnetic couplings are used in API 610 pumps or ASME B73.1 pumps, these negative effects will be eliminated. This does not mean an unsealed magnetic drive pump, but an independent coupling that replaces conventional (standard) flexible couplings. When used in the range...
