3PE anti-corrosion steel pipe features a three-layer structure. It's commonly used in applications such as oil, natural gas, and water supply. Each layer plays a crucial role, and the three layers work together to achieve optimal performance.
Base layer: Also known as the epoxy powder coating, with a thickness of ≥100μm, applied directly to the steel pipe surface, acting as a chemical barrier.
Middle layer: Made primarily of adhesive, with a thickness of 170-250μm, it fuses the epoxy and polyethylene layers to ensure structural integrity.
Outer layer: The polyethylene layer, with varying thicknesses for standard and reinforced steel pipes, ranges from 1.8-3.7mm for standard grades and ≥2.5mm for reinforced grades. It provides excellent resistance to environmental corrosion.
3PE anti-corrosion steel pipe's three-layer anti-corrosion structure ensures its suitability for harsh environments, encompassing a wide range of applications:
Oil and gas: Oil and gas are essential to our lives, so 3PE anti-corrosion steel pipes are required to provide a long service life, high-pressure resistance, and corrosion resistance.
Water conservancy projects: Whether for water recycling or domestic use, anti-corrosion steel pipes are commonly used in water supply projects.
Industrial applications: Transporting corrosive media such as acids and alkalis while ensuring pipe integrity during drainage.
Agricultural applications: Deep well pipes and drainage networks, where chemical soil erosion is a concern.
Now that we've introduced the performance characteristics of 3PE anti-corrosion steel pipe, we know where it can be used. But then, we should be concerned about its quality. We believe that steel pipes manufactured by source manufacturers offer the highest quality. With integrated production control and no outsourcing, intermediary processes not only compromise quality but also increase production costs. Source manufacturers have comprehensive testing systems, ensuring that both strength and thickness are within standard standards. There's no need to worry about inadequate strength or thickness leading to ineffective performance. The service life of high-quality 3PE anti-corrosion steel pipes is up to 30-50 years. They do not require excessive maintenance during use and can reduce maintenance costs.
