3PE anti-corrosion steel pipe manufacturing method
Date: 2015-04-02
Three-layer structure of PE pipe corrosion: a first layer of epoxy powder (FBE> 100um), the second layer of adhesive (AD) 170 ~ 250um, a third layer of polyethylene (PE) 2.5 ~ 3.7mm. Three materials blend to form a solid combination with steel excellent corrosion layer. Diameter range Φ60 ~ Φ1420, 2.5-18mm thickness range between, this is a relatively good corrosion method, generally up to 50 years of life, not only to extend the replacement cycle underground pipeline equipment, and significant cost savings for national construction provides a strong role! 3PE preservative is the most common method of preventing corrosion, in addition to 2PE, 2PP, 3PP, their manufacturing process is almost, but not the same raw materials, such corrosion is characterized by the production process is simple, good corrosion effect, low prices, pipe manufacturing industry generally accepted method for preserving!
