Environmental Protection Production of  PE Coated Steel Pipe Easy Maintenances And Cleanness   

 

 

the information of pe coated steel pipe  

 

 

Technological process of  pe coated steel pipe

 

1.Shot blasting degusting processing for the steel pipe

Before shot blasting degusting,with medium frequency induction heater,the steel pipe should be preheated to 40 to 60 degree,and then through the shot blasting machine, to remove t pe coated steel pipe he water, oil, and dirt contamination, derusting grade is up to GB/T8923-1988 standard, Sa2.5 level(nearly white level) requirements, the depth on the surface of the steel anchor pattern from 40 to 100 microns.

 2.Epoxy powder coating

Before spraying, the steel pipe will be wrapped in kraft paper on both ends, then use medium frequency induction heater, heated the steel pipe to 190-230 degree, the electrostatic spraying method is adopted to epoxy powder, in the high temperature, combination with base material fastness, its anticorrosion performance is superior, the good resistance to chemical corrosion, coating surface density is smooth, wearable, and anti-high temperature.

 3.Extruded adhesive

According to the requirement of the thickness of adhesive layer and polyethylene, by adjusting the extrusion machine lord motor and screw revolution, to meet the requirements of extrusion amount. When the epoxy powder in a gel form, we adopt lateral winding technology, make the adhesive and PE coated on steel pipe, adhesive epoxy powder, polyethylene polymerization to form a three layer structure, after molding,with three rows of roller, make three layer structure fusion compaction, make it a whole system with smooth surface, without bubble and defect.

Adhesive performance of PE extrusion is 230-260 degree; PE aging corrosion resistance is strong, good environmental stress cracking resistance and elongation properties.

4.Cooling of coated pipe

According to the requirements of the three layer structure of the material properties, it requires slow coolingtemperature of cooling pipe should not exceed 60 degree.

5.Jeeping

In the production process, using online electric spark leak detector for coating 100% of leak detection and leak detection voltage is 25 KV. It requires no funneled under 25 Voltage leak detection.

6.Coating products processing

Use groove grinding machine for pipe end for processing and tags.

 

Main materials

Epoxy powder adhesives and polyethylene epoxy powder material, for example, FBE from American 3M company, Dupont resin adhesive and domestic high quality polyethylene materials. 

WIDELY USED

 in industrial materials liquids and the gas transfer piping system such as urban water pipe network,chemical industry, petroleum, natural gas

 

 

 

         

1: Are you a manufacturer or a trading company?

We are a manufacturer which has  more than   2 0 years' history.

2: Where is your manufacturer? How to visit it?

Our factory located in  Yutian Economic Development Zone ,TangShan , China. A bout 1.5 hours drive time to  Beijing and TianJin airport . Mainly producing pre-insulated pipes, HDPE outer protection pipe and 3PE anti-corrosive pipe.

You can take a plane to Beijing or Tianjin .then we could pick up you at the airport .

3: How do we control our products' quality?

We have professional quality control workers and quality inspection center(CNAS lab)  to control the entire production quality.     

4: How do you transport these products?

We use straps to hoist pre-insulated pipes, it can avoid no damage to our products, no hooks for lifting pipe directly. During the handling process, collision, tossing and more ground drag scrolling are strictly forbidden.

In the process of long distance transport, the pipes should be fixed, and not damage outer protecting pipes and insulating layers.

5: Can I customize some other sizes of products?

Yes! We can according to the customer's request.
If you have any other questions, please don't hesitate, contact us.
