Inner and Outer Epoxy Resin Coated Steel Pipe

Inner and outer epoxy resin coated steel pipe / PE and EP Coated Composite Pipe for Water Transfer

1.What is the coated composite pipe?
The pipe is a kind of composite pipe that is coat a special dusty material on the
internal and external surfaces after the special fabrication processing of the basic
pipes, so the pipe has excellent characteristic of high pressure resistance, antistativity,
fire resistance, strong chemical corrosion resistance, etc.
2.what kinds of coating meterial do you use for the coated composite pipe ?
PE and EP ,plastic powder
3.What color for the coated composite pipe?
Black , gray, red, blue, white ect...
4.what is the coating thickness of coated composite pipe ?
400micrometer -1000 micrometer for PE,
100 micrometer - 400micrometer for EP.
5.what type of coating do you use ?
Hot dip for PE, inside and outside painted for EP
6.How to connect the coated composite pipe?
Threaded, grooved, flange, and other.
7. Can you show me the coated composite pipe process?
Surface treatment- Preheat -Spray -Touch up - baking curing -cooling -parity
(End of the plastic tube can be tested, including appearance, coating thickness,
corrosion resistance, wear resistance, density, hardness, combined with Strength
or adhesion, etc. )- packing and shipping
8.How to inspect the coated composite pipe ?
1. Appearance To visual quality of plastic coating
2.Thickness By Electromagnetic gauge
3. Adhesion experiments according to CJ/T 120-2008(7.4.2)
9. What is the features of coated composite pipe ?
Advantage:
It has excellent corrosion resistance, at the same time, the plasitc coating itself also
has good electrical insulation, does not produce electrical erosion. Low water
absorption, high mechanical strength, low coefficient of Mocha, to achieve the purpose
of long-term use. Can effectively prevent damage to roots and soil environmental
stress and other plants, the connection is convenient, simple maintenance.
Shortcoming:
It can't be bended .
10.What is the application of the coated composite pipe ?
A. All kinds of circulating water system for Civil and Industry
B. Fire service
C. All drainage conveyance, In particular, the cold and hot water system in Hotel, restanrant, and Upscale residential area.
D. Chemical geography pipes, crossing pipe
E. Ventilation pipe for mine.

Plastic coated steel pipe packaging normally are bundles, losses or client option in bundle with strip or in
bulk or according tocustom opinion , 25 tons/container for pipe with usual outer
diameter. For 40" container the max length is 12m.
