non-corrosive coating pipes

After the plastic coating, the steel pipe surface be more smooth, the wear-resistant, and anticorrosive performance be improved
Golan anti- corrosion material co., ltd is a Sino-foreign joint venture of Shan Dong Energy Machinery Co., ltd and Canadian Technology Co .,ltd for the mining tube developing and manufacturing.
According to the requirements of the mine operating requirements, we developed the polyethylene covering clad steel tube, with drainpipe, air pipe, injection pipe and gas drainage pipe 4 series, 152 models.
After the plastic coating, the steel pipe surface will be much more smooth, the wear-resistant, and anticorrosive performance be greatly improved, the service life also be lengthened. Widely used for the mine, water supply and drainage, vent line, heat supplying pipe etc.

Characteristics
Excellent anti-static performance
Special PE material, the anti-static material is evenly coated on the tube surface and internal layer, the resistance can be lower than 1.0×10
6
Ω.
Flame retardant property
With flame retardant material in the coating.
Excellent adhesion of the coating
After the inner side sand blasting and outside ball blasting surface treatment, the adhesion of the coating ≥ 30N/10mm.
Corrosion preventive, no fouling and small fluid resistance
Best bright finish of the surface, small resistance.
Excellent mechanical performance
Good tenacity of the coating, high mechanical performance of the steel tube.
Easy connection
Ring flange, quick coupling etc can be used with the original pipes and valves, with very strong compatibility.
Application
Coal mine system
Water supplying pipes, drainage pipes, positive draft pipes, induced draught pipes, guniting pipes and gas drainage pipes.
Heat supplying network system
Underground and circulating pipes.

The nominal outer diameter can be: (mm)
60, 76, 89, 108, 114, 140, 159, 168, 219, 273, 325, 356, 406, 457, 508, 610.

Main Technical Data
Appearance
Inner and outer coating is smooth without any flaw which impairs use such as cracks, pinhole, and adhering material and so on. The two ends with the tube axis at right angles
Flattening test
Coated steel pipe(nominal diameter is more than 60mm) was reduced to 2/3, no cracks or damage, the coating without peeling off or broken.
Bending test
Coated steel pipe (nominal diameter is less than 60mm) in a bending test, without cracks or damage, the coating without peeling off or broken.
Hydraulic test
Coated pipe does not appear to leak under hydraulic tests
Drop hammer
After drop hammer test, 9 of 10 samples is free of cracks and damage, the coating without peeling off or broken.
Adhesion
Not less than 30N/10mm
Surface resistance
Alcohol burner combustion is less than
Alcohol torch burning
Flame combustion is not more than 3s, any is less than 10s
Combustion is not more than 20s, any is less than 60s
