It is recommended to use polyethylene anti-corrosion adhesive tape with a special primer for external anti-corrosion of the
steel pipeline. This anti-corrosion process has low requirements on the construction site and no pollution. It can be prefabricated for anti-corrosion and then repaired after welding flaw detection and pressure test. It can be backfilled. This process has a short construction period and a good anti-corrosion effect.
The anticorrosion of buried
steel pipelines requires that the thickness of ordinary grade epoxy coal tar is greater than 0.3mm. Process: First coat a layer of primer, and then coat three top coats; if the thickness of epoxy coal tar reinforced grade is greater than 0.6mm, first coat a layer of primer, and then coat the topcoat.
Epoxy coal tar lacquer with extra-strengthened thickness greater than 0.8mm first coat a primer, then top coat, coat a layer of glass cloth, then coat a topcoat, coat a glass cloth, coat a topcoat, and coat a glass The most suitable environment temperature for epoxy coal tar pitch is 5℃～30℃.
