3pe防腐钢管母材包括无缝钢管，螺旋钢管和直缝钢管。三层结构的聚乙烯(3PE)防腐涂层以其良好的抗腐蚀性、抗水气渗透性以及力学性能等，在石油管道行业得到了广泛应用。3PE防腐钢管一防腐层对于埋地管道的寿命来说是至关重要的，同样材质的管道，有的埋在地下几十年不腐蚀，有的几年就发生泄露。就是因为它们采用了不同的外防腐层。

3PE防腐钢管通常即是所说的3PE防腐钢管，指的即是通过防腐技能加工处理，能够有效地防止或减缓在运送与使用过程中发作化学或电化学反响发作腐蚀表象的钢制管道，现在3PE防腐钢管开展成了更多的商品，当前是常常常用的一种3PE防腐钢管(三层聚乙烯)技能即是上世纪90年代后期从国外引入的的防腐技能
3pe anticorrosive steel pipe base metal includes seamless steel pipe, spiral steel pipe and straight seam steel pipe. Polyethylene ( 3pe ) anticorrosive coating with three-layer structure has been widely used in petroleum pipeline industry for its good corrosion resistance, water vapor permeability and mechanical properties. 3pe anticorrosive steel pipe - anticorrosive coating is crucial for the life of buried pipelines. some pipelines made of the same material are buried underground for decades without corrosion, and some leaks occur in several years. It is because they adopt different external anticorrosive coatings. 3pe anti-corrosive steel pipe is commonly referred to as 3pe anti-corrosive steel pipe, which refers to steel pipes that can effectively prevent or slow down the appearance of chemical or electrochemical reaction attack corrosion in the process of transportation and use through anti-corrosive processing. now 3pe anti-corrosive steel pipes have become more and more commodities, and at present, a commonly used 3pe anti-corrosive steel pipe ( three-layer polyethylene ) skill is an excellent anti-corrosive skill introduced from abroad in the late 1990s.
