通过对欧洲聚乙烯防腐层30年应用史的回顾,虽然理论上剥离防腐层下会发生腐蚀或应力腐蚀开裂,但目前还没有发生剥离防腐层下出现膜下腐蚀或应力开裂的案例。对于防喷淋、洒水系统的给水管路具有卓越的适用性就是因为它们采用了不同的外防腐层。对直缝钢管、螺旋钢管等各种管道都可以加工防腐管道可分为两点类,内衬防腐钢管和外壁防腐钢管普通级3PE防腐钢管,石油天然气防腐钢管,3PE防腐:管道三层PE防腐结构:第一层环氧粉末(FBE>100um),第二层胶粘剂(AD)170~250um,第三层聚乙烯(PE)2.5~3.7mm由此得出结论,彻底的表面处理是防止应力开裂的有效手段他们的价格每平方米约相差7元左右。采用三层PE聚乙烯、环氧树脂粉末防腐涂层有如下得点:高效防水防腐,绝缘、抗低温.在国外欧美国家埋地管道的主要也是应该这些防腐涂层.目前我国综合耐用年限、维护费用的因素考虑,首选的是三层PE聚乙烯复合结构防腐涂层管道防腐技术已经用于建筑、石油、电力、冶金、国防、交通贮藏、锅炉、热交换机、风机、车船等工业设备等领域石油输送管道、化工、印染等行业输送腐蚀性介质的工艺管道。

加强级3PE防腐钢管的防腐施工方法,防腐保温涂层:在中、小口径的 热输原油或燃料油的管道上,为了减少管道向土壤散热,在管道外部加上保温和防腐的复合层。常用的保温材料是硬质聚氨脂泡沫 塑料,适用温度为-185~95℃。这种材料质地松软,为提高其强度,在隔热层外面加敷一层高密度聚乙烯层,形成复合材料结构, 以防止地下水渗入保温层内。如外护管是聚乙烯管,无需再做防腐聚乙烯无臭,无 毒,手感似蜡,具有优良的耐低温性能(低使用温度可达-70~-100℃),化学稳定性好,能耐大多数酸碱的侵蚀(不耐具有氧化性 质的酸),常温下不溶于一般溶剂,吸水性小,但由于其为线性分子可缓慢溶于某些有机溶剂,且不发生溶胀,电绝缘性能优良。
 
3PE防腐钢管的防腐施工方法,3PE防腐涂层防腐是用涂料均匀致密地涂敷在经除锈的金属管道表面上,使其与各种腐蚀性介质隔绝,是钢 管防腐最基本的方法之一。钢管防腐涂层越来越多地采用复合材料或复合结构。这些材料和结构要具有良好的介电性能、物理性能 、稳定的化学性能和较宽的温度适应范围等。
 
内壁3PE防腐涂层:为了防止管内腐蚀、降低摩擦阻力、提高输量而涂于管子内壁的薄膜。常用的涂料有胺固化环氧树 脂和聚酰胺环氧树脂,涂层厚度为 0.038~0.2毫米。为保证涂层与管壁粘结牢固,必须对管内壁进行表面处理。70年代以来趋向于 管内、外壁涂层选用相同的材料,以便管内、外壁的涂敷同时进行。
