The function of the steel wire layer of the rubber hose is to withstand pressure and improve the strength and stiffness of the steel wire braided rubber hose. Therefore, the requirements for the steel wire layer are sufficient strength, good fatigue resistance, low elongation, high strength, good bonding strength with rubber, and the material can be copper plated steel wire.

Steel wire braided rubber hoses can withstand high working pressure and pulses, and most of the damage during use is caused by improper use. Damaging the internal structure of the hose will accelerate its damage, and it is not caused by the quality of the hose itself. Fracture is usually not caused by high static pressure, but by instantaneous impact pressure, which is related to the strength and frequency of the pressure impact. During the operation of construction machinery, sudden increases or decreases in pressure may repeatedly occur inside the rubber hose, causing repeated pressure impacts and exacerbating damage to various parts. The instantaneous pressure during the use of construction machinery can easily damage the structure of the rubber hose, leading to the rupture of the inner rubber. Therefore, during the operation, the pressure will gradually increase, which will effectively prolong the service life of the hose.

GB/T11182-2006 (Steel Wire for Rubber Hose Reinforcement) specifies various types of steel wires, each with a different tensile strength. Taking into account the company's cost and product quality factors, selecting standard strength (ST) steel wire can meet safety requirements. For braided hoses, steel wire with a diameter of 0.295mm and a strength of 2750Mpa is generally used.

In practical applications, different specifications of rubber hoses are selected with different numbers of steel wire layers, and the burst pressure of the hose is calculated using a calculation formula to achieve the standard pressure level. The manufacturing of steel wire braided rubber hoses uses a wide variety of raw materials and complex processes. The selection of suitable formula and structural design for the target product through a large amount of experimental data is a prerequisite for producing high-quality products.
