loading arm rotary joints are widely used in our production and life. When this equipment is connected with other equipment, it has the following three crimping forms:
1. Stripping and crimping: A certain length of the outer rubber layer needs to be stripped during crimping. This method is suitable for GB/T3683-92, GB/T10544-03, DIN20022, SAE100R1A/R2A and other standard steel wire braided hoses and steel wire wound hoses;
2. Crimping without peeling the outer rubber: When crimping the crane tube rotary joint, there is no need to peel off the outer rubber layer. It is suitable for fiber braided hose and SAE100RIAT/R2AT and other types of steel wire braided hose;
3. Stripping inner and outer rubber crimping: When crimping, a certain length of inner rubber layer and outer rubber layer should be stripped off. It is suitable for GB/T10544-89 large diameter pipe and SAER12, DIN20023-4SH and other ultra-high pressure steel wire wound hose.
