Direct burial of steel pipe is not a good practice though. First, for corrosion protection, the pipe would have to be mill wrapped with a plastic coating. A thermite weld wire is required from the pipe to a magnesium anode as well as for electrically bonding the couplings. In the end, apply an insulating mastic pipe coating on any exposed steel. CSST can be used if your town allows it, but when buried, it must be installed inside a suitable sleeve (PVC) that is gas-tight and is vented at each end. Many CSST manufacturers also require only trained individuals to install the transition fittings. 0 Reply Share Share Share on Facebook Share on Twitter Share on LinkedIn Share on WhatsApp Leave an answerLeave an answerCancel reply Attachment Select file Browse Featured image Select file Browse Save my name, email, and website in this browser for the next time I comment.
