What is the difference between TPEP anticorrosive steel pipe and 3PE anticorrosive steel pipe ?

TPEP anticorrosive steel pipe and 3PE anticorrosive steel pipe are upgrading products on the basis of the outer single layer polyethylene and internal epoxy coated steel pipe, it is the most advanced anticorrosive long distance steel pipeline buried underground. Do you know what is the difference between TPEP anticorrosive steel pipe and 3PE anticorrosive steel pipe?

Introduction of 3PE anti-corrosive coating steel pipe

What is the difference between TPEP anticorrosive steel pipe and 3PE anticorrosive steel pipe

 

 

 

 

 

 

 

 

 

 

 

Coating Structure

The outer wall of TPEP anticorrosive steel pipe is made of 3PE hot-melt junction winding process.  It is composed of three layers, epoxy resin(bottom layer), adhesive(intermediate layer) and polyethylene(outer layer). The inner wall adopts the anti-corrosion way of thermal spraying epoxy powder, and the powder is evenly coated on the surface of the steel pipe after being heated and fused at high temperature to form a steel-plastic composite layer, which greatly improves the thickness of the coating and the adhesion of the coating, enhances the ability of bump resistance and corrosion resistance, and makes it widely used.

 

3PE anticorrosive coating steel pipe refers to the three layers of polyolefin outside anti-corrosion steel pipe, its anticorrosion structure generally consists of three layer structure, epoxy powder, adhesive and PE, in practice, these three materials mixed melting processing, and steel pipe firmly together, forming a layer of polyethylene (PE) anticorrosive coating, has a good corrosion resistance, resistance to moisture permeability and mechanical properties, is widely used in the oil pipeline industry.

 

Performance Characteristics

Different from the general steel pipe, TPEP anticorrosive steel pipe has been made internal and external anticorrosive, has a very high sealing, long-term operation can greatly save energy, reduce costs, protect the environment. With strong corrosion resistance, convenient construction, its service life is up to 50 years. It also has good corrosion resistance and impact resistance at low temperature. At the same time, it also has high epoxy strength, good softness of hot melt adhesive, etc., and has high anti-corrosion reliability; In addition, our TPEP anticorrosive steel pipe is produced in strict accordance with national standard specifications, obtained anticorrosive steel pipe drinking water safety certificate, to ensure the safety of drinking water.

 

3PE anticorrosive steel pipe made of polyethylene material, this material is marked by good corrosion resistance, directly extend the service life of anticorrosive steel pipe;

3PE anticorrosive steel pipe because of its different specifications, can be divided into ordinary grade and strengthening grade, the PE thickness of ordinary grade 3PE anticorrosive steel pipe  is about 2.0mm, and the PE thickness of the strengthening grade is about 2.7mm. As an ordinary external anticorrosion on casing pipe, the ordinary grade is more than enough. If it is used to directly transport acid, alkali, natural gas and other fluids, try to use the strengthened grade 3PE anticorrosion steel pipe.

 

The above is about the difference between TPEP anticorrosive steel pipe and 3PE anticorrosive steel pipe, mainly reflected in the performance characteristics and application of different, the correct selection of the appropriate anticorrosive steel pipe, play its due role.
