Compression Resistance of Polythene Coatings for Welded Joint on Pipeline

Abstract:

With indentation and puncture tests, this article chooses several typical 3PE heat shrinkable sleeve field coating material, characterizes their compression resistance and influence factors by determination on the proportion of indentation depth (PID) and bursting strength. The result shows that temperature has significant effect to PID, the average PID is 4.75% and 11.70% separately on the condition of 10MPa, 23°C and 50°C; the bursting strength is mostly influenced by thickness, with the minimum of 1216N; the original density has no effect to compression resistance.
