After the metal hose in use, how to change the previous earthquake found overseas, in the earthquake, the tank and its piping connected to the occurrence of absolute displacement, which occurred in a lot of stress, so that the pipe with the convergence of equipment, pipe fittings, fixed support, etc. accepting excessive force and torque, severe, can damage the tank, the occurrence of liquid leak accident. In order to increase stress, destruction of customer service way above retail building industry metal hose, piping shall piecemeal designed to have sufficient flexibility. The metal hose sufficiently flexible that it can reduce stress in the pipeline construction industry specializing in the production of metal hoses, increase pipeline to storage tanks, thrust bearing, so as to maintain the tank. Why metal hose will be broken? Metal hose stainless steel mesh cover mainly protective bellows and bellows to withstand internal pressure media (mainly axial force). Nets covering the bellows metal hose outside the construction industry quality assurance, both ends of the bellows and the end ring and joint welding. (1) Weld cause screen sets to pull off because of the quality of welding, the bellows, ring and steel wire mesh sleeve Weld in part caused by the welding process Trinity (over-burning or welding on the end). After loading hose pipe so uneven force due to the wire, at medium pressure, Weld at the wire to pull off the whole steel mesh sleeve to pull off, resulting in failure of the outer drum bellows construction industry with metal hose, dangerous. To put an end to this situation, should improve the welding quality, water pressure and leak test should be carried out before the assessment hose factory, after passing to the factory. (2) improper installation, causing the screen to pull off retail construction industry with metal hose hose _ _ Hopen construction industry with metal hose by Hao Peng Ning County, stainless steel metal hose Limited. Ning County Hopen stainless steel metal hose Limited (www.haopengguanye.com) (www.haopengguanye.com) is Dezhou, hoses leaders, over the years, the company implementing the scientific management, innovation and development, the principle of honesty and trustworthiness , the maximum meet customer needs. In Hopen hose leadership with the staff warmly welcome all inquiries negotiations to create Hopen hose better future.
