Low pressure natural gas line
Low pressure natural gas line
(OP)
My company is working on a project in North Florida on which we have to relocate several utilities. I know about the sewer, water, etc., but have not worked on a natural gas line before. My question is what standards are used, what materials and fittings are used, how do you avoid conflicts? Anything in particular to watch out for?





RE: Low pressure natural gas line
As for your question, it depends on the existing design. Might be steel or Polyethylene, or even another material. No way for me to tell. Best thing is to get hold of the existing drawings and specifications. If you can do that, buying to the same specs may be a possiblity.
Last, get a local PE on a retainer fee. One that has some gas design experience. You'll probably need a PE sooner or later anyway. Take the opportunity to get to know one.

We will be getting an MEP to look at this.
It is a private gas line, low pressure (20-30 psi), about 2"-3". Part of the problem is that it was built in the 40's or 50's, so I'm worried about simply matching what's out there.
We've run into similar problems before. The architect will expect us civils to design the line since it's outside and the MEP doesn't want to do it for the same reason.

Have a look here; a link to some typical HDPE pipe & fitting materials for gas distribution. See 6800 series. Study up on the Heat Fusion guide too.
