Stainless steel pressure resistant metal hoses are flexible components made of stainless steel corrugated pipes with one or more layers of steel wire or steel belt mesh sleeves, and are used to transport various media with joints or flanges at both ends. They are characterized by corrosion resistance, high temperature resistance, low temperature resistance (-196 ℃~+420 ℃), light weight, small volume, and good flexibility. Widely used in industries such as aviation, aerospace, petroleum, chemical, metallurgy, electricity, papermaking, wood, textiles, construction, pharmaceuticals, food, tobacco, and transportation.
