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.
Flexible damping rubber joints, also known as damper, pipe damper, compensator or flexible joint, etc., are divided into single-ball, double-ball, concentric reducer, eccentric reducer, elbow, clamp and American standard joints, etc. They are featured by small size, light weight, high elasticity, high air tightness and convenient maintenance; after installation, it allows universal displacement and won't be affected by user's eccentric pipeline or unparallel flanges; during operation, they can also reduce structure transmitted noises and have a strong vibration absorbing ability. In high-temperature resistant, acid and alkali resistant and oil resistant pipelines, it can prevent the corrosion of corrosive media to rubber joint more effectively, thus improving the service life.
Non-metallic compensator, also known as flexible expansion joint (fabric compensator), is composed of non-metallic complex and metal structural components. Non-metallic complex is mainly made from high-performance fluorosilicone rubber cloth, polytetrafluoroethylene film, alkali-free glass fiber cloth and aluminum silicate (cotton) cloth, etc., through the technology optimal combination of hot pressing, gluing and sewing, etc. This product has the abilities of universal compensation and absorbing thermal expansion thrust, causes no reverse thrust (no rigidity or rebound), is simply structured and has the strengths of vibration isolation, noise reduction, high (low) temperature resistance, corrosion resistance, light weight and easy installation and maintenance, etc.
