低温固化熔结环氧粉末在钢质管道三层PE防腐中的应用

摘要

随着国内长输油气管道建设的迅猛发展，以及高钢级管线钢在长输油气管道中的推广应用，与常规固化熔结环氧粉末涂层物理化学性能相同的低温固化熔结环氧粉末，不仅能够节能降耗，而且具有更好的结合钢质管道三层PE外防腐工艺等优点，将更加广泛应用于长输油气管道三层PE外防腐。%　　With the quick construction of the long distance oil and gas pipelines, and the application of High-grade pipeline steel in the long distance oil and gas pipelines in China, Low temperature cured fusion bonded epoxy which have the same physical and chemical performance with conventional cured fusion bonded epoxy not only can save energy and reduce Consumption, but also can be more propitious to the process of 3PE coating for steel pipeline. It also will be more widely applicated in 3PE coating for the long distance oil and gas pipelines.
