How is the working pressure of hydraulic rubber hoses determined?
The pressure resistance of hydraulic hoses is completely determined by the number of layers of steel wire reinforcement, weaving/winding method, and steel wire diameter, which are the basis of working pressure:

Core principles and processes of wire rope crimping machine
Working principle: Cold state non cutting plastic processing; The high-pressure hydraulic drive causes the mold to close, allowing the aluminum sleeve to flow fully in the mold cavity and tightly wrap around the steel wire rope strands. By relying on the friction between the steel wires and the shaping and locking of the sleeve body, a high-strength joint is formed without damaging the original wire strength of the steel wire rope;
