3PE three-layer protective layer–Details of anti-corrosion steel pipe

3PE anti-corrosion steel pipe refers to a 3-layer structural polyolefin coating (MAPEC) outer anti-corrosion steel pipe, which is a commonly used anti-corrosion pipeline in China. At present, 3pe steel pipe is widely used and is an indispensable steel pipe in the pipeline industry. Do you know why 3PE steel pipe is so popular?

1. Long service life:
We all know that steel products are prone to serious corrosion in harsh environments, which reduces the service life and years of steel pipes and increases costs. The service life of thermal insulation anti-corrosion steel pipes is relatively long. Generally, it can be used for up to 30-50 years, which will invisibly reduce the cost of use. Not only that, but correct installation and use can also reduce the maintenance cost of pipelines, and anti-corrosion thermal insulation steel pipes can also set up alarm systems to automatically detect official website leakage faults, accurately identify fault locations, and automatically alarm.

2. Good thermal insulation performance: 3PE anti-corrosion and thermal insulation steel pipe has good thermal insulation performance, and the heat loss is only 25% of that of traditional pipes. Although there is no obvious effect in short-term operation, it can save a lot of resources in long-term operation, significantly reduce the operating cost, and has relatively strong waterproof and corrosion resistance. 3PE anti-corrosion and thermal insulation steel pipe can be directly buried underground or in water. The construction is also very convenient and quick, and the comprehensive cost is not high. Due to its anti-corrosion and thermal insulation characteristics, it also has good corrosion resistance and impact resistance under low-temperature conditions. The full name of the 3PE anti-corrosion layer is the fused epoxy/extruded polyethylene structural protective layer, which is mainly composed of the following three layers. The first layer of fused epoxy, the middle layer of adhesive, and the last layer of extruded polyethylene, the total thickness of the protective layer is not less than 1.8mm and not more than 3.7mm. During the production process of 3PE anti-corrosion steel pipe, these three materials will be mixed and integrated into one by winding and original mold coating processing methods, so that the steel pipe is combined with it to form an excellent anti-corrosion layer to achieve the anti-corrosion effect of the steel pipe. This anti-corrosion coating production technology is a clever combination of the European 2PE anti-corrosion layer and the North American epoxy powder anti-corrosion steel pipe coating. It has been used all over the world for more than ten years, and its effect is very good. The three-PE anti-corrosion coating has the characteristics of high impermeability and high mechanical properties of epoxy resin and polyethylene materials. It is currently recognized worldwide as the best pipeline anti-corrosion coating method with the best use effect and performance, so it is widely used in many projects.
