Gongyi Liangda Tubes Co. Ltd

we are offering flexible metal hoses, corrugated hose etc. a flexible metal hose flexible metal hose is a flexible metal line element.corrugated hoses can withstand high pressure and provide maximum leak tightness on account of their material. corrugated hoses also exhibit corrosion resistance and pressure tightness under the most extreme conditions, such as in aggressive seawater or at extreme temperatures such as found in space or when transporting cooled liquid gas. they are particularly well suited for conveying hot and cold substances. with a history of more than one hundred years, metal hoses have given rise to other flexible line elements, including metal expansion joints, metal bellows and semi-flexible and flexible metal pipes. corrugated hoses are pressure and vacuum tight. the permissible operating pressures for hoses with small dimensions reach 380 bar (with a 3-fold burst pressure safety factor). the pressure resistance of large dimensions is lower for technical reasons. stainless steel models have a temperature resistance of up to approx. 600 c, depending on the pressure load, and even higher values are possible with special materials. in the low temperature range, stainless steel corrugated hoses can be used down to -270 c.leadingmanufacturer ofrubber expansion joints, dismantling joints, expansion bellows, duckbill valves, flap valve, pinchvalve etc.
