直埋蒸汽管安装的要点

直埋蒸汽管是最近几年在蒸汽管道安装使用的一种组合材料,其由蒸汽管、保护钢管、保温层、蒸汽管固定架及防腐层等组合而成,与管廊蒸汽管、架空蒸汽管相比具有不占空间、不占用地、不易受损、不影响环境等优点。本文介绍了直埋蒸汽管的施工程序,从材料进货检验,蒸汽管道焊接、保护管道焊接、蒸汽管蒸汽吹扫及管道回填等施工过程中的要点、施工方法及应该注意事项,严格整个过程控制。

Main Points of Buried Steam Pipe Installation

Buried steam pipe is a kind of combination material used in steam pipe installation in recent years.It is connected by steam pipe,pipe protection,insulating layer,steam pipe coating fixation and other combinations.It is different from the gallery steam pipe and the overhead steam pipe,it has the advantages of occupying no space,being not easy damaged and effected by environment.This paper introduced the construction procedures of buried steam pipe,from the testing of shopping materials,welding of steam pipe and protection pipe,steam purge and backfilling,construction methods and other attentions.The whole process was strictly controlled.
