Crack resistance of a welded butt joint of polyethylene pipes

Crack resistance of a welded butt joint of polyethylene pipes

The problem of predicting the indices of long-term strength of welded joints of polyethylene pipes is outlined in the present paper. Fracture mechanics methods allow determining crack resistance limit IC of a welded butt joint of PE3PE, PE80, and PE100 polyethylene pipes at a temperature of 213 K. T...

Zusammenfassung:The problem of predicting the indices of long-term strength of welded joints of polyethylene pipes is outlined in the present paper. Fracture mechanics methods allow determining crack resistance limit IC of a welded butt joint of PE3PE, PE80, and PE100 polyethylene pipes at a temperature of 213 K. The IC values in the junction area are less than in the base material for all the tested polyethylene pipe types. Herewith, PE100 has shown better weldability in comparison with the other specimens.
