The function of metal hose
The function is to connect the mesh sleeve with the entire corrugated pipe, at the same time, the joint is also the component that connects the metal hose and the metal hose to other pipe fittings and equipment. It ensures that the medium works properly in the piping system. The material of the joint is usually the same as that of the bellows and mesh, and most are stainless steel.
In order to reduce production costs, some metal hoses with larger diameters can be made of carbon steel when transporting non-corrosive or non-corrosive media. Metal hose couplings for aggressive media (if designed) take appropriate measures to avoid contact with the media and can also be made of carbon steel. The structure of the joint is roughly divided into three categories: screw type, flange type and quick type: under high working conditions, the joints of metal hoses (explosion-proof pipes) with a thread diameter of less than 50 mm are mostly threaded. After tightening the threads, the inner and outer cone surfaces of the two fittings fit tightly to achieve a seal. The taper angle is usually 60 degrees, but 74 degrees is also useful. The structure has good sealing performance, but the concentricity of the two mating parts must be ensured during installation. In order to solve the problems of repeated disassembly, assembly and concentricity that often occur in practical projects, the joint can also be designed to match the cone and ball head.
