VAM TOP is similar to buckle oil casing coupling short connection variable buckle The surface pressure of the head seal. After tightening the buckle according to the specified torque, the joint has good sealing performance even under the action of tension, compression, bending and other loads. Torque shoulder, setting the surface of the torque shoulder is beneficial to accurately control the tightening position of the joint and reduce the hoop stress at the joint. -20 torque shoulder surface, which can improve the actual effect of self-locking after the connector is tightened.

The thread is made, and the bearing side of the thread profile is 3, which eliminates the common failure of the joint slipping that may occur under the action of the tensile load of the oil pipe coupling, so that the threaded joint has better joint strength. Various pitch diameters are available to increase the efficiency of belt buckles when attaching connectors. There are many threaded connectors, which can improve the stress distribution range of the connector when the oil pipe is loaded. Internal connection, the connector is fixed on the pipeline with screws, and there is no shoulder between the inner holes for continuous connection, which can eliminate the possibility of fluid in the pipeline depending on the connector. seepage. Coupling formulation.

On the premise of ensuring 2100% connection efficiency of oil pipe joints, improve the outer diameter and total length of the joints, and improve the specifications of oil pipe joints as much as possible. Surface treatment, the sealing surface, torque shoulder surface, thread tooth and other surfaces of the coupling are plated with a specially formulated and well-proportioned copper alloy coating, which can further improve the anti-stick performance of the shackle threaded joint.
