Steam pipeline purging should be carried out after the insulation work on the pipeline system is completed
Thread Content
Why must steam pipeline purging be carried out after the insulation work on the pipeline system is completed? Thank you!
To reduce heat loss and save steam. It is also to prevent people from getting scalded by the pipes.
It seems that this is mentioned in the pipeline standards, but not all parties necessarily follow it; see http://bbs.hcbbs.com/thread-1067630-2-1.html
