Specific methods for buried anti-corrosion of fire protection pipelines The anti-corrosion requirements for buried pipelines are that the thickness of ordinary grade epoxy coal tar should be greater than 0.3mm. Process: first apply a layer of primer, and then apply three layers of topcoat; For epoxy coal tar paint with a reinforced thickness greater than 0.6mm, apply a layer of primer first, then a layer of topcoat, followed by glass cloth, and finally a layer of topcoat, wrapped in a layer of glass cloth, and then two layers of topcoat. Epoxy coal tar paint with a reinforced thickness greater than 0.8mm should be applied with a layer of primer first, followed by a layer of topcoat, wrapped in a layer of glass cloth, then a layer of topcoat, wrapped in a layer of glass cloth, then a layer of topcoat, wrapped in a layer of glass cloth, and finally two layers of topcoat. The suitable ambient temperature for the construction of epoxy coal tar is currently between 5 ℃ and 30 ℃. If the anti-corrosion of buried pipelines in the external network is used in harsh environments with corrosion, or if required by customers, topcoat and glass cloth can be added to increase the anti-corrosion ability and level. The main anti-corrosion measures for buried pipelines include natural gas and oil pipeline networks, cold and hot water pipeline networks, high-temperature steam pipeline networks, sewage pipeline networks, fire protection external network pipeline systems, and domestic water supply systems.

Anti corrosion pipeline: General municipal engineering mainly involves water supply, drainage, transportation of liquids or gases, etc. But the inner wall of the water supply needs to be treated with anti-corrosion material IPN8710 drinking water coating. The external protection pipeline depends on one's own requirements, and the application environment and cost of the above anti-corrosion materials vary. Still the same, it depends on the requirements of the project. Steel lined PO pipes, storage tanks, and other non-standard equipment PO are homopolymer copolymers of ethylene and propylene, with superior acid, alkali, salt, and organic solvent resistance. They are not susceptible to electrochemical corrosion and can be safely used for a long time in the temperature range of -40-85 degrees Celsius. The surface of the product is smooth, and the lining layer and steel surface are tightly bonded, with a low friction coefficient and excellent resistance to foreign objects and wear. Steel lining PO processing technology: using a hot rolling axis one-time forming process, the whole is formed in one go. For larger equipment and pipelines, we also use a layer of turtle shell mesh of corresponding specifications on the surface of the substrate to increase the adhesion between the lining layer and the substrate. It can be used in negative pressure environments and is one of the ideal materials to replace stainless steel and other special steels. The corrosion resistance of steel lined PE pipes, storage tanks, and other non-standard equipment PE is similar to PO, and the processing technology is also the same, but the temperature used is slightly lower, with a high usage temperature of 70 degrees.
