Butt Welded Flexible Metal Hose
Size DN15(1/2”)- DN400(16”)
Butt Welded Flexible Metal Hoses we designed and manufactured are according to GB/T14525-2010 latest standard with good characteristics of large diameter, high temperature resistance, high pressure resistance and high corrosion resistance. The hoses are widely used in domestic and foreign oil & chemical industries, metallurgy, shipbuilding, gaspipe network, refrigeration, vehicle and pharmacy industries ect. And our products had applied all over the world with good reputation from customers.
Welded Flexible Metal hose is one of the most important jointing elements in engineering technology which is consisted by flexible metal hose, outer protecting wire and connection joints each side. It is applied in pipelines of gas transmission, liquid transmission and length, temperature, location compensation system as compensation elements, sealing elements, connection elements and shock absorption elements. So it is widely applied in aeronautics and astronautics, petrochemical industry, machinery shipbuilding, medical treatment and public health and energy sources industries etc. For many territories, the butt weld flexible metal hose is a good element. We also have many similar products, such as flanged flexible metal hose, threaded flexible metal hose, stainless steel quick joint flexible metal hose pipe and so on.
