Seeking advice on the pressure rating for steam tracing pipelines
Thread Content
The control installation manual lists only PN63 and PN160 as the available specifications. Since the heat tracing at the site uses low-pressure steam at 1 MPa, must pipe and valve components of grade PN63 be used for the heat tracing pipelines? Can we use PN20 grade? ? Are there specific guidelines? ?
Is there anyone who can help answer this?
First, communicate thoroughly with the actual client; unless they agree and provide a written design change, the design must be followed as planned. Another instrument system is the eyes; it’s right to have higher requirements for them. :P
Sorry, I wrote a word wrong.:lol First, communicate thoroughly with the design firm; unless they agree and provide a written design change, one can only proceed according to the original design. Another instrument system is the eyes; it’s right to have higher requirements for them.
Just construct according to the design drawings. Unless it can be discussed when there is room for modification. As long as the temperature and pressure requirements are met, there is no problem.
