Stainless steel hose Encyclopedia

I. Introduction stainless steel metal hose stainless steel hose is compiled one or more wire or steel mesh cover made of stainless steel bellows, but ends with the first connector or flange, stainless steel hose for transporting a variety of media The flexible element. Second, the stainless steel hose Description: Construction: loose flange with straight pipe welded steel mesh cover bellows features: seismic performance, strong protective nets diameter: DN6 ~ DN2000 materials: (1) Bellows : stainless steel 304,316L, 321, etc. (2) flange, takeover: carbon steel, stainless steel 304,316L, 321, etc. (3) nets: stainless steel 304,316L, 321 flange standards: GB GB, American Standard ANSI, Japanese standard JIS, German standard DIN, etc. Features: metal hose corrosion, high temperature, low temperature (-196 ℃ ~ + 550 ℃) light weight, small size, flexibility, and is widely used in petroleum, chemical, metallurgy, power, water treatment, environmental protection, paper, construction and other industries. Third, metal hose bellows Category: stainless steel metal bellows pressure hose used in two ways, one is a spiral bellows; the other is an annular bellows. Spiral bellows: Bellows spiral corrugated spiral arrangement of tubular housing between two adjacent corrugations have a helix angle, all the ripples can be connected by a spiral. Toroidal bellows: annular corrugated tube is corrugated in a closed annular tubular housing, in series between the wave and wave ripples made by the ring. Toroidal bellows formed from seamless pipe or welded pipe processing. Constrained by the processing methods, compared with spiral bellows, its single-tube length is usually shorter. Advantages annular bellows is elastic, small stiffness. Fourth, the product code examples five, stainless steel metal hose applications: austenitic stainless steel pressure metal hose stainless steel material or the production of user requirements, has excellent flexibility, corrosion resistance, high temperature resistance (-235 ℃ ~ + 500 ℃), high pressure resistance (up to 32MPa), in the pipeline can be connected to any direction for temperature compensation and absorb vibration and reduce noise, change the medium conveying direction, eliminating mechanical pipe or between pipes and between devices displacement, double flange metal corrugated hose to have displacement, vibration of pumps, valves and other flexible joints is particularly applicable.
