The forms of anti-corrosion coating for plastic coated steel pipes include inner and outer epoxy resin powder coated steel pipes, inner epoxy resin powder coated steel pipes, and outer polyethylene powder coated steel pipes. The latter is superior to the former, not only able to resist corrosion, but also able to withstand impact and effectively resist external mechanical damage (such as sand and gravel in backfill soil of buried pipelines). Anti corrosion coated plastic steel pipes are based on spiral or seamless steel pipes, with high adhesion coating on the outer wall
