fire resistance, strong chemical corrosion resistance, etc.
2.Coating meterial : PE and EP
3.Color : black , gray, red, blue, white
4.Coating thickness:
400micrometer -1000 micrometer for PE,

7. 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.Inspecting:
| 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.Grooved steel pipe features:
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.Grooved steel pipe application:
