Anti corrosion steel pipe is the abbreviation of three-layer polyethylene anti-corrosion layer, which is a anti-corrosion technology applied in the petroleum pipeline industry. It adopts a three-layer structure of epoxy powder, adhesive, and polyethylene, firmly wrapping the surface of the steel pipe to form a solid anti-corrosion layer, effectively preventing corrosion of buried steel pipes.
The base materials of 3PE anti-corrosion steel pipes include seamless steel pipes, spiral steel pipes, and straight seam steel pipes. The three-layer polyethylene anti-corrosion coating has excellent corrosion resistance, water vapor permeability resistance, and mechanical properties, and has been widely used in the petroleum pipeline industry.
The anti-corrosion layer of 3PE anti-corrosion steel pipes is crucial for the lifespan of buried pipelines. Some pipes of the same material are buried underground without corrosion for decades, while others leak within a few years because they use different external anti-corrosion coatings.
Anti corrosion steel pipes usually consists of a three-layer structure: the bottom layer is an epoxy powder coating, the middle layer is an adhesive, and the outer layer is a polyethylene coating. The design of this three-layer structure ensures that the anti-corrosion layer has good mechanical properties and chemical stability, effectively preventing the penetration of water and oxygen, thereby protecting the steel pipe from corrosion.
Anti corrosion steel pipes are widely used in multiple fields, including:
1. Petroleum field: used for transporting fluids such as oil and natural gas, preventing the surface of pipelines from being affected by corrosion, oxidation, etc., improving the service life of pipelines, and ensuring the safe transportation of fluids within pipelines.
2. Natural gas field: used for transporting natural gas and other fluids, preventing the surface of pipelines from being affected by corrosion, oxidation, etc., improving the service life of pipelines, and ensuring the safe transportation of fluids within pipelines.
3. Chemical industry: Used for transporting chemical raw materials, chemical reagents, and other fluids, to prevent the surface of pipelines from being affected by corrosion, oxidation, etc., improve the service life of pipelines, and ensure the safe transportation of fluids within pipelines.
4. Ship field: used to transport cooling water, lubricating oil and other fluids from ships, prevent pipeline surfaces from being affected by corrosion, oxidation, etc., and improve the safety and service life of ships.
5. Construction industry: It is an important field for the application of 3PE anti-corrosion steel pipes, including municipal infrastructure fields such as urban tap water, heating network, gas network, HVAC, etc.
6. Petrochemical, metallurgical and other fields: Because the working environment in these fields is usually harsh, it is necessary to prevent corrosion and damage to steel pipes.
7. Marine engineering, shipbuilding, power and other fields: 3PE anti-corrosion steel pipes have excellent corrosion resistance in harsh conditions such as marine environment and salt mist.
