Line width in the piping diagram
Thread Content
May I ask, in a piping layout diagram, what thickness is ideal for the main process line? 0.7 or 0.8?
It depends on your regulations; generally, we use 0.7 for levels above Diagram 1 and 0.6 for levels below Diagram 1. You can ask your colleagues at the company; they probably all have their own rules. This post was last edited by swallowam on 2009-2-10 08:41]
The standards vary from company to company. If there are no specific regulations (most companies have such regulations), as long as the thick lines and thin lines you draw can be clearly distinguished from each other, that’s sufficient
Many units* are used with thick lines 0. 8
Depending on the density of the pipelines, if there are many pipelines, use thick lines of 0.6, medium-thick lines of 0.4, and thin lines of 0.25; if there are few pipelines, use thick lines of 0.7, medium-thick lines of 0.4, and thin lines of 0.25
Every design institute has its own rules; they all differ. In our institute, the process pipelines that are installed new are all 0.5 mm in diameter.
You can get the drawings from your company and check their properties to find out how thick they are
