What are the factors endangering the purchase of metal hoses
(1) For the pound class outer diameter of metal hose, select the tee joint mode (mainly flange connection, British thread connection and quick tee joint connection), the degree of metal hose and the length of plastic hose.
(2) Pressure, according to the social practice pressure of metal hose, and then query the wavy metal hose pressure gauge to decide whether to use the metal hose of stainless steel mesh sleeve type.
(3) Chemical substances, the analytical chemical characteristics of the chemical substances transported in the metal hose, and the raw materials of various parts of the plastic hose according to the corrosion resistance of the raw materials of the plastic hose.
(4) Working temperature and enterprise scale of chemicals in metal hose; Operating temperature of plastic hose during operation. In case of high temperature, the pressure after temperature review shall be distinguished according to the working pressure and temperature review index value of metal hose under high temperature, so as to distinguish the correct pressure.
(5) According to the condition of metal hose selection, with reference to the quasi application of metal hose, the mode of machinery and equipment, the good length of plastic hose in concrete crack compensation, various sports and fitness forms of plastic hose, the length carry forward cost of condition, the hardship times and radius of plastic hose, the length of plastic hose shall be selected according to the basic parameters, and the machinery and equipment shall be properly.
