Coating applied in a factory to individual pipe lengths is often referred to as “linepipe coating” (or “factory coating”), see DNV-RP-F106. In this document, “parent coating” is sometimes used synonymous with linepipe coating.
其中,让我最不明白的就是“linepipe coating”是管线管涂层吗,是个什么意思呀,还有“parent coating”是个什么涂层呢,这是关于海底管道补口的一个规范里的内容,文章中总是出现,实在是混不过去了,求各位大侠帮助,谢谢谢谢
