Coverage in line pipes include of high costs. For this selecting cover and how apply is high important. Three fold polyethylenes include ofepoxy layers, adhesive and polyethylene. Eachother from layers having attributes that increasing its application for long term. Polyethylene layer is good shelter for prevent ofphysical damages. In attention to corrosion in lower temperature is an electrochemical reaction and rate of an electrochemical reaction is veryimpress of a element or very reactor from surface. This position occurred when influence of a element increasing of other covercontrollers. A example of this issue that will be cause of outer corrosion in pipes under soil and this is very importance in work, this is leakagewater into covers that can be measurable with coefficient of water leakage that can exchanging layers quality. This article has studied leakage water into three fold polyethylene cover.
