Stainless steel metal hose pipe can reduce the installation stress in many complex piping system, there will be space constraints, the fixed pipe is not installed, electrical metal hose, not bent, is, however, mandatory installation can cause fracture and cold calibration. Doubtless great risks. Give the installation work has brought great convenience, the safe operation of the pipeline system also plays a certain role in safeguarding. This is the main reason some pipeline systems metal hose must be used. A model of the engine in the section bearing lubricant conduit, in actual operation, multiple fractures accident occurred, since the metal hose can be bent and curved bend radius at rated conditions of internal stress generated minimal. 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 outside of the bellows, the bellows ends and the end ring and joint welding. (1) Weld cause screen sets to pull off because of the quality of welding, electrical and metal hose with perfect quality, the bellows, ring and steel wire mesh sleeve Weld in part caused by the welding process Trinity (burnt or the end of weld on). 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 jacket pulled off, causing the outer drum bellows failure, dangerous. To prevent this from happening, electrical metal hose ease of use, should improve the quality of welding, electricity prices with a metal hose, hose factory should be carried out before the water pressure and leak test evaluation, after passing to the factory. (2) improper installation, causing the screen to pull off a professional wholesale electrical metal hose, hose Hopen (certified), electrical 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.
