should i chose black pipe nipples for gas piping

should i chose black pipe nipples for gas piping

(OP)
i have shifted to a new home and wondering which piping connection will suits best for my requirement. I have been using black pipe nipples from shanghai rolling threads since past 2 years and it worked perfectly fine for me. It just need to ask that either black pipes works exactly the same for water piping or should i choose some other option.

RE: should i chose black pipe nipples for gas piping

Black steel pipe is acceptable for gas pipe, but I would not use it for water pipe, nor is it allowed in the International Plumbing Code.

RE: should i chose black pipe nipples for gas piping

Black pipe would start leaking from corrosion within a few years of water service.

RE: should i chose black pipe nipples for gas piping

Black only for Gas
Galvanized only for Water

Using Galvanized on gas can result in zinc debris ending up clogging a valve or nozzle in your gas appliance.

RE: should i chose black pipe nipples for gas piping

Use copper for potable water. It is anti-microbial and is a proven winner.

As a side note, I grew up in a house with galvanized and black steel pipe for water and gas. No problems that I remember.

RE: should i chose black pipe nipples for gas piping

Galvanized pipe will work but it will have a limited lifetime as galvanized pipe is susceptible to corrosion and scaling.

The plumbing industry seems to moving to PEX.

Correcting my post above to make it more explanatory:

Galvanized pipe will work for water service but galvanized pipe will have a limited lifetime as galvanized pipe is susceptible to corrosion and scaling when used for water service.

The plumbing industry seems to moving to PEX for water service.

Some areas allow galvanized pipe for gas service as well.
