The DEJ-B type expansion joint is based on the A-type expansion joint, which changes the key connection method to a hexagonal combination of the outer tube and the central tube to transmit torque. This hexagonal structure torque transmission structure is suitable for high torque construction environments, and the overall torque is much greater than that of the A-type structure. But the internal diameter of this type of tool structure is smaller than that of Type A.

Features/Advantages

The outer cylinder and the central tube rely on hexagonal cooperation for torque transmission, and can transmit torque at any position

Long sealing components with reliable sealing and large expansion and contraction stroke (stroke can be customized)

Adjustable opening pin combination, shear force can be adjusted within the required range

The regular working pressure is 70MPa (10000Psi), and the maximum working pressure is 105 MPa

Normal working temperature resistance is 177 ℃, with a maximum working temperature of 204 ℃
