Flexible Stainless Steel Hoses Seal
Flexible stainless steel hose (sleeves) sealed, are designed for transportation of liquid and gaseous media, for water, steam, condensate, gas and petroleum products, chemical products. Operate in extreme conditions, operating pressures and temperatures.
Spiral shaped convolution spiral advance profiled steel band with subsequent contact and seam welding. They have a diameter of 6 mm to 300 mm and lengths from 250 to 6000 mm. For the production of this type of hose used stainless strip thickness 0,15-0,40 mm.
High-quality steel airtight hose is not advisable to use in systems with a high level of vibration as the exploitation of metal hoses in such conditions leads to a resonant vibration of the corrugations or shells entirely.
Spiral represented by two species - rolled and corrugated variations. Corrugated metal oloruka made of seamless or longitudinally welded thin-walled tubes, which are formed by special mechanical or hydraulic devices and supplied with end fittings. They are used as low-cost flexible connecting elements as loading hoses and of movement, thermal expansion, vibration absorption.
Corrugated metal hose is completely waterproof, can be used to transfer liquids and gases under high pressure. In addition, the hose to the valve can be used in vacuum systems.
Addition weld metal hoses we supply hoses with flange with thread.
Due to the high reliability and durability to impacts flexible connection was in demand in the market pipelines and has been widely used in the automotive, aerospace, shipbuilding, metallurgy, petroleum, chemical, food, medical industry and many other industries.
