3PE/PP Anti-corrosion pipe

Standard:

Outer coating: NF A49-710, DIN30670, CAN CSA 21, CAN CSA 20, SY/T0315 andother relevant national standard steel pipe external corrosion;Internal Coating: NF A49-709, API RP 5L2, SY/T0457 and other relevantnational standard steel pipe coating.

 

Purpose:

The outer coating is mainly used for oil transportation by pipelinecorrosion protection of buried before; mainly from the inner coating reducesdrag reduction pipeline investment and operation and maintenance costs.

 Pipe external corrosion

1, single FBE corrosion (FBE) Single-layerFBE Coating Epoxy powder layer because of its excellent corrosion resistance,insulation resistance and long service life and become an advanced anti-corrosioncoating of the outer pipe. Sub-ordinary nature (thickness: 300 ~ 400um) andenhanced (thickness: 400 ~ 500um) two kinds.

2, double FBE corrosion (2FBE)

Double epoxy powder coated outer coating is a composite structure,consisting of anti-corrosion epoxy powder primer and epoxy powder resistant tomechanical damage the surface layer of a coating film is completed. Normal sex(thickness ≥ 620um); enhanced (thickness ≥ 800um)

3, two polyethylene / polypropylene anticorrosion (2PE/2PP)

Two polyethylene / polypropylene layer with good corrosion resistance,insulation resistance, long service life and resistance to mechanical damage.Sub-normal and enhanced thickness according to pipe size varies: Common Min1.8mm; enhanced minimum 2.5mm.

4, three layer polyethylene / polypropylene anticorrosion (3PE/3PP)

Three layer polyethylene / polypropylene layer with excellent corrosionresistance, insulation resistance, longer service life and a certain degree ofresistance to mechanical damage of the coating has been widely used in variouslarge-scale projects of the corrosion in the pipeline. Common type andstrengthened type two, thickness of the pipe size varies: Common minimumthickness 1.8mm; enhanced minimum thickness of 2.5mm.

Anti-corrosion steel pipe

DN100-1500 can be carried out within a steel pipeanti-corrosion, rust red iron centrifugal spray or two-component liquid epoxypaint or other coatings specified by the user, the treated for corrosionprotection of steel pipe wall processing
