Hydraulic Fittings Company introduces metal hose retrofit commutation, which is offset according to the commutation potential difference. The metal hose pipe should be used, the circuit resistance between the pipe and the surface of the metal hose should be as large as possible, and the wear resistance of the pipe should be better. Therefore, in metal hoses, thermoelectric high-purity graphite pipes are generally selected.

The size and technical requirements of the connection flange and end pipe between the metal hose and the pipe (or equipment) should meet the corresponding standard end pipe connection, and the pipe openings at both ends should be beveled at 30 degrees +/- 2.5 degrees. After the installation of the piping system, the auxiliary positioning mechanism and fasteners used for installation and transportation protection on the expansion joint should be removed immediately, and the limiting device should be adjusted to the specified position according to the design requirements so that the piping system can be fully compensated for the environmental conditions.

A metal hose is a very soft pipe made of metal as raw material. If the metal hose is difficult to replace, then the collapsible pipe should be used. Since the pipe is of metallic nature, some slag will be generated in the pipe, and some slag will affect the welding effect. Therefore, when we use emery cloth or paper to grind away the waste residue in the pipe before welding.

The performance of the sealing material is an important factor in the sealing effect. Select the delivery hose and joint according to the actual working pressure to ensure smooth operation. In addition, there are the pressure and temperature that the metal hose can withstand, the corrosiveness of the medium, etc. The inner layer of the commodity material of the metal hose is made of galvanized strip steel and a unique insulating layer; the surface layer is made of PVC raw materials (anti-ultraviolet light), and the working temperature of the metal hose is -20℃~+100℃.

The working pressure of the metal hose should be adjusted well. If the working pressure is too tight, it will aggravate the damage to the pipeline and the metal hose. But if the pressure is too loose, the contact between the pipe and the hose will not be good, causing some problems. Moreover, the inner surface of the brush holder box should be smooth and tidy, and there should be no problems such as burrs.
