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.

Integration of them and solid steel pipe make form a good coating.

Diameter range 60mm-1420mm, wall thickness 2.5-18mm, which is a good anti-corrosion method, generally can improve the service life of 50 years, not only extended the replacement cycle of the underground plumbing, and significant cost savings for the provides a strong role in nation-building. 

3PE anti-corrosion is the most commonly used method of anti-corrosion, in addition to 2PE, 2PP, 3PP, their manufacturing process is similar to but different raw materials, this anti-corrosion characteristics of the simple fabrication process, the preservative effect, inexpensive pipe manufacturing industry generally agree that corrosion.

ADVANTAGES OF THE THREE-LAYER COATING SYSTEM

·         Excellent corrosion resistance.

·         When exposed to either acid or alkaline media, an extended lifetime in highly corrosive soils is assured.

·         Strong steel adhesion: 20 times more adhesive than traditional plastic tape systems.

·         Excellent cathodic disbondment test results.

·         Excellent mechanical resistance.

High dielectric resistance : Superior bending ability for pipe laying applications

High impermeability: Both the high-density polyethylene and polypropylene have low water permeation characteristics that allow improved isolation from the surrounding sea water compared to other coating systems


3PE anticorrosive steel pipe characteristics:

·         very high tightness,which can greatly save energy, reduce costs, protect the environment in long-term operation.

·         strong corrosion resistance, the construction side simply speed, the service life can be up to 30-50 years.

·         with good resistance to corrosion and impact resistance, low water absorption, the PE (less than 0.01%) at low temperatures.

·         high strength epoxy, PE absorbent and hot melt adhesive softness, etc., have high corrosion reliability.
