3PE ordinary grade anti-corrosion steel pipe refers to a 3-layer structure polyolefin coating (MAPEC) external anti-corrosion steel pipe, which is a commonly used anti-corrosion pipe in China. Three-layer PE anti-corrosion structure: the first layer of epoxy powder (FBE>100um), the second layer of adhesive (AD) 170~250um, and the third layer of polyethylene (PE) 2.5~3.7mm. Other anti-corrosion methods include IPN8710, FBE epoxy powder, epoxy coal pitch and other anti-corrosion methods.
However, everyone still does not know much about various anti-corrosion steel pipe anti-corrosion methods and processes. For example, 2PE/3PE anti-corrosion, 2PP/3PP anti-corrosion, underground anti-corrosion of fire protection pipelines, anti-corrosion of steel-plastic composite pipes, enhanced anti-corrosion of underground pipelines, and epoxy coal anti-corrosion Five major advantages of common anti-corrosion and anti-corrosion steel pipes, such as steel pipe anti-corrosion and PE anti-corrosion steel pipe anti-corrosion. In addition to improving the service life of steel pipes through anti-corrosion, it is also reflected in the following aspects:
o1. Combining the mechanical strength of steel pipes and the corrosion resistance of plastics
o2. The outer wall coating is more than 2.5mm, resistant to scratches and bumps.
o3. The friction coefficient of the inner wall is small, reducing energy consumption.
o4. The inner wall meets the national health standards. o5. The inner wall is smooth and not easy to scale, and has a self-cleaning function.
Construction methods of anti-corrosion coatings for pressure steel pipes (pipes) As the anti-corrosion technology for pressure pipes, coatings and composite materials are the most widely used and common.
For extremely corrosive media, non-metallic corrosion-resistant materials are used.
Corrosion inhibitor technology is also used in certain pipelines in the petroleum and petrochemical industries.
It is also common to use cathodic protection technology for urban underground pipelines and underground long-distance pipelines.
Using paint to prevent corrosion of pipelines is a simple and easy method.
The main basis for choosing a coating is its performance.
