Do you know the causes of corrosion in anti-corrosion steel pipes? Let me give you a brief overview.

The cause of corrosion in anti-corrosion steel pipes is the galvanic corrosion resulting from differences in electrode potentials. When a metal undergoes an electrochemical reaction, the portion with the lower electrode potential readily loses electrons and becomes the anode, while the portion with the higher electrode potential gains electrons and becomes the cathode. In… O2 and H2 Under the presence of, iron element (OH)2 It will produce hydrated iron oxide. ( Commonly referred to as iron rust. ) This is loose material floating on the steel surface, offering no protection. The anodic reaction of the metal continues—meaning corrosion persists—resulting in pitting and perforation on the surface of the oil‑gas pipeline. TPEP Anti-corrosion steel pipes are coated with a two-component, air-curing coating, and the pipe surface is reinforced with glass cloth.

Anti-corrosion steel pipes can be used for external corrosion protection of oil, gas, water, and heat‑transfer pipelines in land‑reclamation projects and underwater applications. They are also suitable for corrosion protection of various steel structures, docks, ships, sluice gates, gas storage tanks, and refining and chemical processing equipment, as well as for leak‑proofing sewage ponds, roof waterproofing layers, and basement concrete slabs. When combined with fiberglass cloth, they can serve as an exterior coating for pipelines, yielding reinforced or further‑reinforced anti-corrosion coatings. Three‑layer‑with‑four‑coat anti-corrosion steel pipes consist of a coating layer and fiberglass cloth, which enhance the mechanical properties of the anti-corrosion coating. The three‑stage silicone oil exhibits excellent electrical insulation, water‑resistance, resistance to microbial attack, resistance to stray currents, heat resistance, and resistance to sudden temperature fluctuations.

Additionally, they are suitable for corrosion protection of various steel structures, docks, ships, sluice gates, gas‑storage tanks, refineries, and chemical plants, as well as for leak‑proofing sewage ponds, roof waterproofing membranes, and basement concrete layers. When combined with fiberglass cloth, they can serve as an exterior pipe coating, yielding enhanced or further‑reinforced anti‑corrosion coatings.

Three‑step silicone oil exhibits excellent electrical insulation, water resistance, resistance to microbial attack, resistance to stray currents, heat resistance, and resistance to sudden temperature changes. The base layer of the anti-corrosion steel pipe is made of epoxy resin, with an intermediate rubber layer and an outer polyethylene pipe. 3 Anti-corrosion layer. In TPTP The inner wall of the anti-corrosion steel pipe is coated with epoxy powder. At high temperatures, the powder melts and forms a coating on the pipe surface, creating a steel–plastic alloy layer. Molten epoxy‑powder‑coated steel pipes are classified as single‑layer or double‑layer systems. In contrast, double‑layer epoxy powder coatings are considered ideal for corrosion protection. The construction principle involves using a single‑layer molten epoxy powder as the primer and a modified molten epoxy powder as the outer protective layer, thereby enhancing the performance of the anti-corrosion coating and meeting requirements for resistance to high‑temperature permeation and thermal shock. The compatibility between the single‑layer welded epoxy powder rust‑preventive coating and the cathodic protection layer has also been investigated.
