防腐保温管技术相关指标

2019-06-02 09:42:40

从我国埋地管道防腐保温技术上来看,保温上主要是运用的硬质聚氨醋泡沫材料进行保温的,防腐层所运用的是聚乙烯夹克及沥青玻璃布两种防护层,在防腐保温管道中,主要是由防腐层、保温层及防护层所构成的复合结构,防腐层主要是防腐涂料,其厚度一般在80μm以上。保温层为硬质泡沫塑料层,其厚度运用经济厚度来计算确定,一般要在2.5cm以上。而防护层则主要为聚乙烯塑料层,其厚度依据管径和施工的工艺确定但一般在1.2mm以上,而且管道防腐保温层的端面要用防水帽进行密封防水。而在油气管道中常用的敷设方式为管沟、架空和直埋敷设,当敷设方式不同的时候,所应用的外保护和保温层材料也就不同,当用架空敷设方式适用站场管道,需要把钢管除去锈之后,再刷上防锈涂料;管沟的敷设方式,比较常用在站内管道及跨越管段中,其钢管除锈之后,再刷上防锈涂料;直埋敷设为温度在100℃之下时,在钢管除锈之后,要在表面进行防腐,而防腐的材料要求是比较高的,现在常用的材料为TO树脂、氰凝、聚氨醋及其它树脂类的涂料。无论何种防腐涂料其性能像柔韧性、附着力及强度等都要符合要求。
