new LP gas line sizing question

[LBrown59]

At the time, I lived on a city lot and felt it was best to pay someone to do a project like that.

You can use the Yellow Plastic Gas Line out doors but it's not permitted inside.
I used it back around 1998 to replace the old rusty leaking one inch black steel pipe at my parents place located inside the city limits.

I have seen this corregated steel stuff installed , but I have never used the stuff.

I sell miles of it. I sell both Trac-pipe and Parker Pipe corrugated stainless steel tubing. It has been around for a while and it is the latest and greatest. Is is about 1/3 more than black iron pipe but the install time is much shorter.

I thought the same way until I heard about the Class Action lawsuit settlement with 4 manufacturers of CSST. You can read about it here
If your area is prone to lightning storms, like ours is, you might want to take the precautions that the manufacturers are recommending.

Inspector507, thanks for that info. I didn't know about that. Most of the "improvements" in materials in the plumbing and heating trade improve the ease or speed of installation, not necessarily the quality of the product. I still like black iron pipe for gas, but I like a lot of the old ways (showing my age).

I was under the impression that the flexible piping mentioned above was for final hook up only and could not exceed 3' in length? anyhow I haven't seen any of the new NFPA86 standards in over a few years...

anyhow good luck.

Spiker ,Under current international gas code you can use this product to pipe an entire house. Each city/ town / county /etc, can & do adopt all of the codes or take out parts that they don't want. So , you may be correct for you'er town/ county/ city/ etc,.

Mark,
What you're used to seeing is a flexible gas connector. It's used to make a flexible final connection to your appliance. CSST is flexible corrugated stainless steel tubing used to pipe the whole house. It's sold by many brand names such as, Omegaflex, Wardflex, Trac-Pipe, Gastite....etc. It does have it's draw backs though.

Inspector, from what I've seen ,all products have their draw backs. black iron pipe is difficult to use & you have to coat it it used under ground, copper will scale, but I don't understand the law suit here. I don't know the wall thickness of this ss flex tubing , but I think it would be the same or thicker than copper tubing & there have been no suits ( that I know of ) against copper tubing for lightening strikes. I have never used the stuff, but The use may increase since the copper prices have gone through the roof.

The class action lawsuit arose due to installers not READING the installation instructions whereas the piping system must be bonded to the electrical grounding system in the house. It has been a NFPA 54 code requirement for years for all gas piping but unfortunately the tort lawyers have had a hard time going after the black iron pipe and copper manufacturers because their names are not required to be marked on the pipeing unlike the corrugated stainless steel guys
