Metal hose brazed joint structure and characteristics

Metal hose connectors are widely used in oil and insulating oil and turbine oil transportation . As a medium delivery hose has a higher pressure and temperature. Therefore, if a leak or desoldering welding parts will cause serious accidents. There are inner and outer metal hose . The inner layer is Φ2O × 2mm hoses. The thin outer layer of woven steel mesh . Two layers are made of 1Cr18Ni9Ti. Hose which mainly acts as a seal . Hydraulic hose fittings mesh from strength to protect ashamed to use . Recently factory production hose three gods in the form ( spiral integral , roll -welded and brazed ) . Since the metal boiler delivery hose at runtime withstand high temperatures and pressures , often subject to bending stress. Therefore recommend the use of the whole spiral hose . Hose transported to the site after the installation of a short stainless steel Hydraulic pipe fittings , while the fine plus a stainless steel outer and brazing , braze weld pipe work must ensure sealing and bear turns force .
