GB/T 2550-2016 Gas welding equipment—Rubber hoses for welding,cuttingand allied processes
Abstract
This standard specifies the requirements for rubber hoses (including parallel hoses) used in welding, cutting, and similar operations.
This standard specifies the requirements for medium-duty 2 MPa and light-duty (limited to a maximum working pressure of 1 MPa with a nominal inner diameter of less than or equal to 6.3 mm) rubber hoses, as well as acetylene hoses (with a maximum working pressure of 0.3 MPa).
This standard applies to hoses with a working temperature of -20 ℃ to +60 ℃ and the following applications:
——Gas welding and cutting;
——Arc welding under inert or reactive gas protection;
——Similar welding and cutting operations, particularly heating, brazing, and metal spraying.
This standard does not apply to thermoplastic hoses and high-pressure (above 0.3 MPa) acetylene hoses.
