  • 3PE anti-corrosion steel pipe

3PE anti-corrosion steel pipe’s material includes seamless steel pipe, spiral steel pipe and straight seam steel pipe. 3PE anticorrosive coating has been widely used in petroleum pipeline industry for its good corrosion resistance, water permeability resistance and mechanical properties. 3PE anticorrosive steel pipe an anticorrosive layer for buried pipeline life is very important, the same material of the pipeline, some buried in the underground for decades not corrosion, some years leak, is because they use different external anticorrosive layer.

 

  • Pipe external coating type

3PE anticorrosion is generally composed of 3 layers:

No.

Materials

Coating thickness

First layer

FBE

>100um

Second layer

AD

170-250um

Third layer

PE

1.8-3.7mm

In practice, the 3 materials will be mixed into one, after processing to make it firmly combined with steel pipe to form an excellent anti-corrosion layer.

The coating of 3PE anticorrosive steel pipe integrates the high impermeability and high mechanical properties of epoxy resin and polyethylene materials. So far, it is recognized globally as the best pipeline anticorrosive coating with the best performance and the best use effect, so as to be applied in many projects.

 

  • Pipe internal coating

The internal pipe is divided into 2 kinds of anticorrosion: one is hot melt epoxy powder anticorrosion (High temperature fusion), other one is liquid epoxy coating, commonly used liquid epoxy IPN8710 (Cold spraying at room temperature). These 2 kinds of internal anticorrosion form process and performance are different, specifically shown in:

Requirement of pipeline using

Internal coating thickness (um)

Drag reduction pipeline (Liquid epoxy coating)

≥50

Anticorrosive pipeline (High temperature fused epoxy powder coating)

Common level

≥250

Strengthen level

≥350
