Do you know the cause of the corrosion reaction of anti-corrosion steel pipes? Briefly.  

The reason for the corrosion reaction of anti-corrosion steel pipe is to corrode the metal through the electrode potential difference. When the metal undergoes an electrochemical reaction, it is easy to lose electrons at a low electrode potential to form an anode. The part with high electrode potential receives electrons and becomes the cathode. In the presence of O2 and H2, elemental iron (OH)2 produces hydrated elemental iron oxide (commonly referred to as elemental iron rust), which are loose substances floating on the steel surface unprotected. The anodic reaction of the metal continues, that is, the corrosion continues, creating pits and perforations on the surface of the LPG pipeline. The TPEP anti-corrosion steel pipe adopts two-component atmospheric curing coating, and the surface of the steel pipe is reinforced with glass cloth.

Anti-corrosion steel pipes can be used for external wall anti-corrosion of oil, gas, water and heat pipes in land reclamation and water. It can also be used for various steel structures, wharfs, ships, sluices, gas tanks, oil refining and chemical plants, anti-corrosion and leakage prevention of sewage pools, roof waterproof layers, and basement concrete layers. It can be used together with fiberglass cloth for pipe exterior paint to make reinforced or additionally reinforced anti-corrosion paint. The three-cloth four-oil anti-corrosion steel pipe is composed of coating and fiberglass cloth, which can improve the mechanical properties of the anti-corrosion coating. Three-stage silicone oil has excellent electrical insulation, resistance to water penetration, resistance to microbial erosion, resistance to suspended current, heat resistance, and resistance to sudden temperature variability.

Three-step silicone oil has excellent electrical insulation, water permeability resistance, microbial erosion resistance, suspension current resistance, heat resistance, and resistance to sudden temperature variability. The base layer of the anti-corrosion steel pipe is epoxy resin, middle rubber, and outer polyethylene pipe with three anti-corrosion layers. Spray epoxy powder on the inner wall of TPTP anti-corrosion steel pipe. The powder melts at high temperature and coats the surface of the tube to form a steel-plastic alloy layer. The molten epoxy powder steel pipe is divided into single layer and double layer. In contrast, double epoxy powders are ideal for anti-corrosion coatings. Construction principle The performance of the anti-corrosion coating is improved by using a single layer of molten epoxy powder as the base coating, and the outer protective layer is made of modified molten epoxy powder, and meets the requirements of high temperature penetration resistance and high temperature impact resistance. The compatibility of single-layer welding epoxy powder antirust paint with cathodic protection layer was studied.
