摘　　要：随着3PE防腐层在埋地钢质管道的大量使用,其缺陷也开始逐步暴露,主要表现为防腐层的剥离。本文就造成埋地钢质管道3PE防腐层剥离的因素:自身缺陷、剥离电位、水和氧的渗透等方面进行探讨。With the substantive application of 3PE-anticorrosive coating on underground steel pipe,its drawbacks are exposed gradually which are mainly reflected in the peeling of anticorrosive coating.This paper discussed those factors which caused the peeling of 3PE-anticorrosive coating,for example,its own defects,peeling potential,permeation of water and oxyen,etc.
