They are waterproof, dustproof, salt-proof, acid-resistant, and alcohol-resistant. The joints at both ends of the metal joint and the flanges are matched with the joints inside the pipe. In modern industry, metal joints are a high-quality soft pipe, mainly composed of mesh sleeves, bellows and joints. The inner tube of the metal joint mainly has a spiral shape and a ring shape, and the mesh sleeve of the corrugated outer layer. The metal joint can connect the unthreaded steel pipe and the equipment outlet equipment to the hose, eliminating the threading process. The material used by the metal joint is formed by pressing the zinc alloy material, and the surface is galvanized and frosted, which helps the structure become denser, and the connection between the steel pipe and the metal joint will be more reliable and the appearance will be more beautiful.
