Corrugated metal hose (referred to as bellows) is a high-quality flexible pipe in modern industrial pipelines. It is mainly composed of corrugated pipes, mesh sleeves, and joints. Its inner tube is a thin-walled stainless steel corrugated tube with a spiral or circular waveform, and the outer mesh of the corrugated tube is woven from stainless steel wire or steel strip according to certain parameters. The joints or flanges at both ends of the hose are compatible with the joints or flanges of the customer’s pipeline. Has good flexibility, corrosion resistance, high temperature resistance, wear resistance, and tensile strength.
