The high-pressure hose is mainly composed of a liquid-resistant styrene-butadiene rubber inner rubber layer, a middle rubber layer, 1, 2, and 3 layers of stainless steel wire hand-braided layers, and a weather-resistant styrene-butadiene rubber outer rubber layer. The effect of force, stainless steel wire is not corroded, the outer rubber layer will not damage the stainless steel wire, the stainless steel wire layer is the frame material High-pressure hose is made of high-quality special styrene-butadiene rubber compound, large-diameter hose mechanical equipment operated by technical electronic equipment manufacture. Under the necessary conditions of high quality and durability, this rubber hose is used in all places where various substances are transported without problems. Therefore, typical main uses are: marine technology, freight logistics, large and medium storage tanks, iron and steel metallurgy industry and construction industry.
As we all know, the high-pressure rubber hose is a kind of pressure-resistant and wear-resistant pipeline, so according to the different working pressures, the selected lifting layer is also different. The stainless steel wire sandblasting hose is the spraying layer with one or two layers of stainless steel wire hand-woven. Sand hose. More common is a layer of stainless steel wire. It can withstand compression to 4Mpa, and the hand-woven double-layer stainless steel wire can withstand compression above 10Mpa.
Installation method of high pressure hose
Proper installation of high pressure hoses is a factor in ensuring that their characteristics are fully utilized. It is generally installed behind the root valve of the tank trade pipeline, and there is also a valve behind the high-pressure hose, which promotes the immediate conduction and soft connection between the tank and the pipeline, which is conducive to maintenance and disassembly.
High-pressure hoses have limited ability to cover axial deflection under natural conditions. When the installation length is equal to the natural length, it will inevitably bear the axial tension and cause the pipe to crack and leak. Therefore, the installation length of the high-pressure hose should be smaller than the natural length to ensure a certain degree of playability.
Due to the lateral and axial offset caused by the high-pressure hose digestion system, in addition to ensuring its playability during installation, it can also be digested according to the reasonable layout of the pipeline. There are two types of extensive threading pipes: L type and Z type. The L type is widely installed, and the overall layout adjustment environment is clean and unique, which reduces the length of the pipe and reduces the frictional resistance of the liquid. However, the axial stress field caused by the pipe will act on the high pressure hose and tank nozzle.
This reduces the service life of high-pressure hoses and stop valves, and also damages the nozzles, resulting in wholesale leakage of refined oil. Although the Z-type installation increases the length of the pipeline and the number of elbows, the axial offset of the pipeline system can be digested by itself, reducing the axial stress field of the high-pressure hose and nozzle, and the service life is also conducive to the stability of the pipeline.
