Pipeline non-destructive inspection
Thread Content
What standards do everyone use when selecting the level of non-destructive inspection of pipelines? How are they divided?
JB 4730-2005, see if this standard is okay.
Non-destructive testing standard for oil and gas steel pipelines SY/T 4109-2005
Commonly used specifications include: GB50235, SH3501, DL5031, etc. generally determine the filming ratio and qualification level of the weld based on factors such as design temperature, pressure, physical and chemical properties of the medium, etc.
That is, the standards of different pipelines are different. I wonder if anyone can give some advice! :)
