twinwelding hose(double hose)This type of rubber hose is applied to gas welding,cutting and attachment procedures e.g. braze welding,medaling and beating and gas cutting of pressure control devices. It is widely applied to NC flame cutter,plasma cutting machine, equipment complex and steel structure.According to the structure,there is single welding hose and double welding hose.The double welding hose,which is also called twin welding hose or parallel hose,refers to parallel merger of two single hoses at the time of manufactering for the convenience of poeration.Either the single welding hose or double welding hose has three grades according to the purpose,ie.RRM and T.Our welding hoses are widely applied to high-end NC welding and plasma cutting machine.Anti-ozone aging:in the standard test chamber,concentration:50+/-5pphm;temperature:40+/-2 degrees centigrade;testing period:72t;without crack.Heat-proof aging:in the standard aging chamber,temperature:70+/-1 degree centigrade;testing period:72t;tensile change:not more than -25%;tensile stretch:not more than -30%.Corrosion resistance:anti-acetone corrosionStructure:1.Inner layer of hose styrene butadiene rubber(SBR);2.Protective layer of hose:blends of styrene butadiene rubber and ethylene-propylene-diene monomer rubber(SBR&EPDM);3.Intermediate reinforced layer;polyester fiber spiral line.Appearance:mill finish or stripe faceGreen or blue outer layer of oxygen rubber hose;Red outer layer of fuel gas hose;e.g. acetylene gas.Applicable temperature:-25 degrees to 70 degrees centigradeBend radius:10time of proper diameter dimensionJoint connection:1.The standard copper fittings of different type are available according to demand2.Please supply specific standard parameters or detailed drawing while placing an order.W.P.20Bar B.P.60BaSpecification: 6.3mm 8mm 10mm etc.Length: (Supply and demand sides through consultationExecutive standard: GB2550-92 GB2551-92Structure: acetylene and oxygen tube connect together, glossy appearance, enhanced layer is a strong polyester textile fibers.
