Flexible metal hose Assembly 304 Stainless Steel flanges

These metal hoses mainly have a stainless-steel inner hose and a stainless-steel braided cover.

Stainless Steel: The most commonly used is 304. There are also 316L and 321.

321 stainless steel can withstand very high temperatures. It has high strength, resists scaling, and provides phase stability with resistance to subsequent aqueous corrosion. 304 stainless steel can be sanitized. It can withstand corrosion from most oxidizing acids but is susceptible to corrosion from chloride solutions or from high-saline environments like coastal regions.

These hoses consist of a flexible inner metal hose enclosed in a flexible metal outer hose. Fittings on the ends of these hoses prevent any material that is being conveyed through the inner or outer hose from moving into the other hose. This allows the inner and outer hoses to be used to convey different materials.
