twin welding hose

Description

Welding Rubber Hose Single welding or twin welding Red, Blue, Green etc color all available High quality with very good price This type of rubber hose is applied to gas welding, cutting and attachment procedures ***** braze welding, medaling and heating and gas cutting of pressure control devices. It&#**9;s 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 manufacturing for the convenience of operation. Either the single welding hose or double welding hose has three grades according to the purpose, ***** R, RM and T. Applicable standard: RMA IP******9, Compatibility Standard: BS EN *******3. Our welding hoses are widely applied to high-end NC welding and plasma cutting machine.
