Scope
Main technical content: This document specifies the main content and basic requirements of heat fusion and electric fusion welding technologies for polyethylene (PE) gas pipelines. This document is applicable to heat fusion butt welding using semi-automatic and fully automatic heat fusion welding machines, electric fusion socket-weld welding and electric fusion saddle-weld welding for gas-use polyethylene pipelines. The heat fusion and electric fusion welding technologies for polyethylene pipes in other medium transmission and distribution systems can be implemented with reference to this document.
