| Abstract: | Polyethylene has the advantages of low price,non-toxic,corrosion resistance,and long service life,and has become the preferred material for the installation of urban gas pipelines.Electro-fusion welding is the most common connection mode of polyethylene pipeline,and the performance and quality of joints are directly related to the safety of the gas pipeline system.From the view of the material,the main factors affecting joint performance were described in detail.The advantages and limitations of the existing destructive test methods were analyzed.The application of nondestructive testing technology in the field of quality assessment of electro-fusion joints has been proposed. |
