中文摘要

近中性pH环境辅助腐蚀(NNPHEAC)给加拿大管道公司带来了巨大的成本,因此也给加拿大消费者带来了巨大的成本。从完整性管理的角度来看,NNPHSCC通过对石油管道进行在线检查或对天然气管道进行流体静力测试来控制。这两种技术中的任何一种都可以在数年内防止在役故障,然后必须重复该过程。对于天然气管道来说,测试周期尤其麻烦,因为水压测试技术只能检测到在水压测试应力下失效的相当大的缺陷。这些手术也非常昂贵。
英文摘要
Near-neutral pH environmentally assisted corrosion (NNPHEAC) represents a substantial cost to Canadian pipeline companies and hence to Canadian consumers. NNPHSCC is controlled from an integrity management point of view by in-line inspection for oil pipelines or by hydrostatic testing for gas pipelines. Either of these techniques provides protection from in-service failures for a number of years and then the process has to be repeated. The testing cycle is particularly troublesome for gas pipelines since only quite large flaws that fail at hydrotest stress are detected by the hydrostatic testing technique. These procedures are also enormously expensive.
