Classification of Ultra-High Pressure Metal Bellows Hose
1.High pressure resistant stainless steel metal hose has the advantages of corrosion resistance, high pressure resistance, good flexibility, beautiful appearance, safety and reliability. Depending on the actual pressure, consider the need for a steel belt or multiple mesh sleeves.
- If the pressure is within the normal range: use a single-layer mesh sleeve to reduce costs
- If the pressure exceeds 1-3 times the pressure of the same pipe body: consider using a multi-layer mesh sleeve.
- If the pressure exceeds 5 times the pressure that the same pipe body can bear or exceeds 5 times. Consider using multiple steel strips.
Second, the introduction of high-pressure stainless steel metal hose: structure: loose sleeve flange, corrugated pipe with straight pipe welded steel belt mesh sleeve Features: good seismic performance, strong protection of mesh sleeve Diameter: DN6 ~ DN2000 Material:
(1) Bellows: stainless steel 304, 316L, 321, etc.
(2) Flange and pipe connection: carbon steel, stainless steel 304, 316L, 321, etc.
(3) Mesh cover: stainless steel 304, 316L, 321 and other flange standards: national standard GB, American standard ANSI, Japanese standard JIS, German standard DIN and other product features: metal hose corrosion resistance, high temperature resistance, low temperature resistance (-196 ℃ ～+550℃) Light weight, small size, good flexibility, widely used in petroleum, chemical, metallurgy, electric power, water treatment, environmental protection, paper making, construction and other industries.
- Classification of ultra-high pressure metal hose bellows:
There are two types of bellows used in stainless steel pressure-resistant metal hoses, one is spiral bellows; the other is ring bellows. Spiral bellows: A spiral bellows is a tube-shaped shell with corrugations arranged in a spiral shape. There is a spiral angle between two adjacent corrugations. All corrugations can be connected by a spiral line. Annular bellows: Annular bellows is a tube-shaped shell with corrugations in a closed ring shape. The waves are formed by a series of circular corrugations. The annular corrugated pipe is formed by seamless pipe or welded pipe. Restricted by the processing method, the length of the single tube is usually shorter than that of the spiral bellows. The advantages of the annular bellows are good elasticity and low rigidity.
