The role of the steel wire layer of the hose is to bear pressure and improve the strength and stiffness of the hose. Therefore, the requirements for the steel wire layer are to have sufficient strength, good fatigue resistance, small elongation, * *, and good bonding strength with rubber. Copper plated steel wire can be selected as the material.

Gb/t11182-2006 (steel wire for rubber hose reinforcement) stipulates various types of steel wire, and each type of steel wire has different tensile strength. Considering the * * cost and product quality factors of the enterprise, the steel wire with standard strength (st) can meet * * requirements. For braided hose, generally, the steel wire with diameter of 0.295mm and strength of 2750mpa can be selected.
In practice, different steel wire strands should be selected for different specifications of hoses, and the bursting pressure of hoses should be calculated by using the calculation formula, so as to meet the pressure level required by the standard.
In the rubber hose industry, there are thousands of * * enterprises of medium and low-end hoses; The * * enterprises of high-end hoses are * *, mostly foreign manufacturers; The price of high-end hose is 3-7 times that of ordinary hose. From this, we can see the importance of process design! Quality is always the inexhaustible driving force for the development of an enterprise, and technology determines quality. There are many kinds of raw materials and complex processes for the manufacture of rubber hoses. Through a large number of experimental data, selecting the formula design and structural design suitable for the target product is the premise guarantee of producing high-quality products. I believe that more and more enterprises will realize the importance of process design, which will also become a decisive factor in the success or failure of enterprise development.
