3PE Steel Pipe Anti-Corrosion Coating Machine Line,Coating Equipment For Steel Pipe

3PE anti-corrosion steel pipe production line,automated and easy to install

Product Description

Description:
3PE anti-corrosion coating production line means the steel pipe is protected by three layer to prolong the life of use from 5-10years to 50-100years.
First layer is Fusion bonded epoxy layer (FBE> 100µm), the second layer of adhesive (AD) 170 ~ 250µm, the third layer of polyethylene (PE) 2.5 ~ 3.7mm. Present we can made the machinery for diameter range Φ159 ~ Φ1220.
3PE steel pipe outer coating has a high mechanical strength, excellent electrical insulation performance. The merits include high degree of mechanization, process parameters stable, not pollute the environment, etc. In recent years, the intensive of the pipeline corrosion engineering has been widely used.

3pe have Long-term corrosion resistance

FBE components have excellent adhesion to steel, providing excellent long-term corrosion resistance and protection for pipelines operating at moderate temperatures.

If desired, low application temperature (LAT) FBE can be selected as a primer to ensure low preheating conditions and long-term integrity of high strength steels (X80 or higher)

In addition, 3LPE systems have excellent cathodic stripping resistance, reducing the life cycle cost of cathodic protection

Shandong Industry Information Office said that the 426-1220 bending pipe winding 3PE anti-corrosion production line of Hua Shida has developed an accurate fixed arc technology, the use of alloy flared pushing head to expand the diameter of the steel pipe, eliminate the internal stress during heating deformation, and then rapid cooling and tempering treatment, so as to obtain an accurate arc pipe. The existing CNC equipment can not accurately handle the problem of rebound, elongation and forming radius. The coaxial winding device of radian pipe is designed. The asynchronous principle of internal and external axis and the technology of internal expansion and shrinking diameter are adopted to solve the winding problem of different diameters and the same linear speed, and the continuous accurate automatic winding is realized. High voltage electrostatic spraying technology was developed to realize automatic electrostatic spraying processing and effectively improve the uniformity of surface spraying of steel pipe. The surface coating is thin and uniform, good gloss, and the coating has good adhesion, high hardness and good corrosion resistance. Fluidization boiling technology is applied to realize automatic control of FBE powder heating and melting, which is convenient to operate, low energy consumption and stable physical properties. The Venturi powder pump powder jet technology is applied to reduce the powder spitting phenomenon of powder spray gun, improve the effect of powder spraying, powder rate up to 90%, and reduce the maintenance times of equipment.
