3PE anti-corrosion steel pipe base materials include seamless steel pipes, spiral steel pipes and straight seam steel pipes. The three-layer polyethylene (3PE) anti-corrosion coating has been widely used in the oil pipeline industry due to its good corrosion resistance, water vapor permeability resistance and mechanical properties. The anti-corrosion layer of 3PE anti-corrosion steel pipes is crucial to the life of buried pipelines. Some pipelines of the same material will not corrode after being buried underground for decades, while others will leak within a few years. It is because they use different external anti-corrosion layers.
3pe anti-corrosion spiral steel pipe is a pipe (steel pipe) used in different workplaces. One of the common methods for anti-corrosion steel pipes is to apply it evenly and tightly on the surface of rust-removed anti-corrosion steel pipes to isolate it from various corrosive media. 3pe anti-corrosion steel pipes are pipes (steel pipes) used in different workplaces. In order to slow down or prevent the pipeline from being eroded and damaged due to chemical, electrochemical or microbial metabolic activities in the external medium, 2 or 3 layers of polyethylene (3PE) are coated on its outer wall to achieve anti-corrosion of the pipeline.
Characteristics of 3PE anti-corrosion steel pipes
1. Good anti-corrosion performance: The outer polyethylene coating of 3PE anti-corrosion steel pipe has excellent chemical stability and electrical insulation properties, which can effectively prevent steel pipes from corrosion. At the same time, the adhesive in the middle layer can enhance the adhesion of the coating and improve the anti-corrosion effect.
2. Strong durability: 3PE anti-corrosion steel pipes are made of advanced coating technology and have good weather resistance and wear resistance, and can be used in harsh environments for a long time without being damaged.
3. Excellent mechanical properties: 3PE anti-corrosion steel pipe not only has excellent anti-corrosion properties, but also has good mechanical properties and can withstand large external pressure and impact forces. This makes it widely used in oil and gas transportation, water supply and other fields.
Application areas of 3PE anti-corrosion steel pipes
Petroleum industry: 3PE anti-corrosion steel pipes are widely used in oil well casings, oil pipes, oil pipelines, etc. in the petroleum industry.
Natural gas industry: 3PE anti-corrosion steel pipes are widely used in gas transmission pipelines, natural gas storage equipment, etc. in the natural gas industry. It can effectively prevent steel pipes from moisture corrosion and sulfide corrosion, ensuring safe transportation of natural gas.
Chemical industry: 3PE anti-corrosion steel pipes are widely used in chemical pipelines, storage tanks and other equipment in the chemical industry. It can effectively prevent steel pipes from being corroded by chemical substances and ensure the safe operation of chemical equipment.
Water supply industry: 3PE anti-corrosion steel pipes are widely used in water supply pipelines, water treatment equipment, etc. in the water supply industry. It can effectively prevent steel pipes from being corroded by water and microorganisms in the water, ensuring the health and safety of water supply.
