Original Wear resistant hose It's different from today's. It is carried out bit by bit. Initial Wear resistant hose It is composed of seamless steel pipe and spiral steel pipe. Although the bending stiffness of this kind of seamless steel pipe is very large, its bearing capacity is large, and it is easy to cause flames when it is used, and the service time is long. This kind of pipe fittings is short and difficult to transport, but the production process is relatively simple and has a wide range of applications.

The wear-resistant hose is made of glass fiber elastomer material, and its main component is glass fiber. FRP anti-corrosion and wear-resistant hose has the advantages of light weight, bending rigidity, non corrosion, etc. Glass fiber reinforced plastic anti-corrosion and wear-resistant hose also has many defects, such as poor ductility, thin and brittle relativity, poor impact resistance, heat resistance, etc., which should be noted in application. Three kinds of wear-resistant hose are made of wear-resistant hose, which is anti-static, lightweight, good ductility, corrosion resistance, etc. It is the choice to make wear-resistant hose, but this kind of raw materials cannot be rolled.

For the rubber hose of drainage pipe made of such raw materials, we further mentioned Wear resistant hose The wear-resistant hose is invented. Its appearance improves the past shortcomings, further improving the corrosion resistance of the wear-resistant hose, but the net weight.

The installation of wear-resistant hose shall be carried out strictly according to the process. In the process of CBM extraction, local ventilator is selected and CBM with relatively high concentration of fresh air diluent is used to reduce the concentration of CBM below. When the concentration of coalbed methane in the coal lane is relatively high and there is continuous coalbed methane with relatively high concentration, only the local ventilator is selected.

The hose and hose assembly should be handled carefully, not dragged on sharp and rough surfaces, and not bent or flattened.

The drainage pipe is selected to absorb the steam with higher concentration immediately, without diluent and being limited by the steam concentration value. By comparison, the extraction rate of coal-bed methane is multiple times that of coal-bed methane, greatly accelerating the response speed to accidents and reducing the damage caused by accidents.
