Metal hose is a kind of excellent flexible pipe element. It is generally composed of bellows, mesh (set) and pipe fittings: the raw material of bellows and mesh is acid-proof stainless steel; pipe fittings are made of the same steel with combustion flue. Users may also select other materials according to actual needs (i.e., the interior uses tetrafluoroethylene pipe as lining, etc.). Metal hose allows larger angular displacement and can withstand higher working pressure. It is widely used in printing and dyeing, textile, petrochemical, chemical, paper making, shipbuilding, iron and steel, mechanical and port industries, etc. Especially for pipeline dislocation caused by foundation settlement of high-rise building, petroleum tank and gas tank, it has a good connection effect; in iron and steel industry, oxygen lance of converter steelmaking is also a typical occasion where metal hose is used.
Metal bellows compensator is composed of single or multiple bellows and end connector. It absorbs axial and radial displacements through flexible deformation of bellows. It is a kind of indispensable flexible connector in heating pipe network and hydraulic pressure system. Due to many excellent properties, it is widely used in astronautic, shipbuilding, metallurgical, machinery and electric power industries, product design standards: GB/T12777-2008, American EJMA standard. Before delivery, it will pass 100% pressure and air seal tests and reach all indexes of customer, so the quality is reliable.
