3PE Three Layer Coated Steel Pipe , DIN30670 Coated Gas Pipe Underground

Product Name : 3pe Steel Pipe three-layer polyethylene coating for steel pipe Supply By JFE Steel Corporation

Three layer polyethylene anticorrosion is one of the main technical system of buried pipeline corrosion protection at home and abroad.

It has good corrosion resistance, low water absorption and high mechanical strength.

It has been used more and more widely in the field of buried water conveyance, gas transmission and pipeline transportation in recent years.

Product specifications: diameter of 48– with 3000

Material: Q235B, Q345B, 10# steel, 20# steel, X42-X80 grade and so on.

Implementation standard: GB/T23257-2009 technical standard for polyethylene anticorrosion coating for

buried steel pipeline

SY/T0413-2002 technical standard for polyethylene corrosion resisting layer of buried steel pipeline

DIN30670-91 technical standards for polyethylene coatings for steel tubes and fittings in Germany

CAN/CSA-Z245.21-M92 Canadian technical standard for polyethylene pipe anticorrosive coating on outer wall

Uses: products are widely used in oil pipelines, natural gas pipelines, heating pipes, water pipelines.

Pipe has three layer PE antisepsis structure: the first layer with epoxy powder (FBE> 100um),

the second layer with adhesive (AD), 170 ~ 250um,

the third layer with polyethylene (PE) 2.5 ~ 3.7mm.

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

3PE anticorrosive steel pipe characteristics:

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

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

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

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