Grain metal hose features

Grain metal hose features:1, the recommended maximum allowable amount of expansion of each wave: full-height △ α = ± 24mm half-high △ α = ± 12mm.
2, block gray plate: less dust on the air duct pipe may not be used for dusty flue should file gray board.3, to reduce the number of bellows node should be considered cold drawn 50%.4, the standard half-height corrugated metal hose for cross-sectional area lessthan 4.6 square meters and the smoke duct dimensions less than 1.5m in one side but greater than Hydraulic tube fittings 0.6mm occasions. Standard full-height corrugated metal hose for all the smoke duct.Corrugated metal hose has good flexibility, fatigue resistance, high pressure, high temperature resistance, corrosion resistance, and many other features, it is relative to other hoses (rubber, plastic hose) much higher lifetime would therefore it also has a high overall economic efficiency. With the development of modern industry, for high temperature, high pressure corrugated hose you also demand greater and greater.Hose Scope: need fully flexible pipes, to prevent vibration premises piping for steam, gas, air, heavy oil, petroleum, chemical-pharmaceutical etc apply.
