And add a can of cold galvanizing spray.When I first started out in business I had a partner at first who had more experience in the trade than I had and we ran into a situation where we needed to offset a 2" GRC for a mast riser. But back then I had no tooling for bending rigid steel conduits of that size . His suggestion was this: We fill the pipe with some sand right off the beach at Pipeline, and seal up the ends and then use a cutting torch to heat up the conduit and bend it like PVC , and viola' it works, but that was the only time I ever tried that one. You make the pipe glow cherry red and it gets soft. Work the length just like it was a pvc pipe you were bending using a propane torch with a cherry stone head attachment. After bending pour a bucket of water on it and let it cool down for a good while. Oh, and wear welders gloves.
