Scope
This part of GB/T 20674 specifies the terms and definitions, classification, main performance requirements, operating procedures, test methods, inspection rules, technical documents, and markings of electric fusion welding machines (hereinafter referred to as "electric fusion welding machines") used in polyethylene (PE) pipeline systems. This part applies to electric fusion welding machines used for electric fusion connections in polyethylene (PE) pipeline systems. Pipes and fittings used for electric fusion connections in polyethylene gas pipeline systems shall comply with the provisions of GB 15558.1-2003 and GB 15558.2-2005, respectively. Pipes and fittings used for electric fusion connections in polyethylene drinking water and general pressure water supply pipeline systems shall comply with the provisions of GB/T 13663-2000 and GB/T 13663.2-2005, respectively. This part applies to electric fusion welding machines controlled by voltage or current. Electric fusion welding machines are suitable for fittings heated by resistance wires. The normal operating temperature range of electric fusion welding machines is -10℃ to +40℃. If the operating temperature exceeds this range, the user and the equipment supplier shall consult and agree upon it. Electric fusion welding machines are divided into two input voltage levels: low voltage (LV) from 50 V to 240 V and safety extra-low voltage (SVLV) from 0 V to 50 V. Note: If the electric fusion welding machines are used for connecting other components (such as valves, steel-plastic conversion, etc.) in polyethylene pipeline systems, the user and the equipment supplier shall consult and agree upon it.
