Implementation and Analysis of Quality Management for Polyethylene Gas Pipelines
The necessity of establishing and im-plementing strict technical standards for PE pipeline materials(PE compound,PE pipes and PE fittings)for gas use,developing supplier quality review standards,and evaluating the effectiveness of incoming inspection results is analyzed.By analyzing the requirements of PE electrofusion welding tools,critical electrofusion steps and the relationship between PE electrofusion en-ergy and environmental temperature,the energy range of PE electrofusion under different environmental tem-peratures is proposed.
