... Abstract Polyethylene (PE) pipe has been widely used in the transportation natural gas, and electrofusion (EF) welding is a welding method commonly used in the welding of polyethylene pipes. Defects are likely to occur in electrofusion joints, which lead to significant casualties and economic...

... Abstract Polyethylene pipe has been used widely in gas transportation and nuclear safety-related cooling water applications due to its exceptional resistance to corrosion and erosion. Butt fusion joint is one of the main welding forms for polyethylene pipes. Ultrasonic technique is a typical...
