野外长输管道的建设工作是十分难进行的,施工过程中要对地理环境等进行多方面考量,尤其是在低温环境下的长输管道的工作作业,要考虑到低温这种极端条件,在做好保温防护的同时也根据地形特点设计管道施工路线,并且对管道的日后维护也要考虑进去,在施工设计中就要考虑到管道长期处于低温环境中的可能,做长久使用打算。本文就针对低温环境下野外长输管的低温保护工作做论点,进而对其施工方法进行讨论。
Field long-distance pipeline construction is very difficult to carry out, the construction process to conduct a multi-dimensional consideration of the geographical environment, especially in the low-temperature environment of long-distance pipeline work, taking into account the extreme conditions of low temperature, at Good thermal insulation at the same time, according to the characteristics of the terrain design pipeline construction routes, and pipeline maintenance should also be taken into account in the construction design should take into account the long-term pipeline in the low-temperature environment may do long-term use intended. In this paper, the low-temperature field in the wild long-term protection of low-temperature protection to do the argument, and then discuss its construction methods.
