Natural Gas Piping

Natural Gas Piping

Natural Gas Piping

(OP)
What type of paint or insulation to the pipe that we shall apply. Carbon steel pipe, sch. 40. In underground we have channel to pass the NGP.


Thanks

RE: Natural Gas Piping

The paint is intended to prevent the corrosion process of the carbon steel pipe due to the environment is crossing. You need to disclose a lot more of your secret gas pipe if you expect a meaningful answer. Is the pipe burried in the ground and emerges in some short channels? Is the pipe always running in a channel? Is the channel wet or dry? Insulation for temperature? Hot? Cold? Is the galvanic corrosion an issue?
Cheers,

RE: Natural Gas Piping

For sure it won't be paint you will need.  There is an entire industry dedicated to making and applying coatings to underground piping.  Start by googling, or calling up the natural gas distributor in your area.

Purple.

RE: Natural Gas Piping

tapecoat or poly/epoxy coating would be better for ug.  Why insulate a gas pipeline?

RE: Natural Gas Piping

RE: Natural Gas Piping

NGP is likely natural gas product (liquid condensates such as ethane and higher extracted from the gas).

RE: Natural Gas Piping

Duwe6,
       I would prefer jte's purple to yellow....but then a nice shade of green could blend in better with the surroundings if it's outside...

RE: Natural Gas Piping

UPC, uniform plumbing Code has information on materials and procedures
to install NG Piping.
If transmission lines other Codes apply.
