Type D big interference degree of the performance characteristics of loose tube expansion
Type D loose tube with large deflection compensation joint connector is loose tube with large deflection compensation in absorbing foreign advanced technology and combining with our country the truth on the basis of research and development of a new type of pipe connector. The main structure of the short tube flange, ontology, gland, gear ring, set blocks, seal, compression artifacts, used to absorb the axial displacement and deflection for 6 ° ~ 7 ° angular displacement slip-on pipe connection device. It adopts the unique design of shaft resistance of simple structure, reliable sealing performance, tensile force. Has a larger scale and quantity of the flexible, suitable for bad condition, the complex terrain of pipe connection.
