Quick Details
Specifications
PLASTIC COATING STEEL PIPES FOR COAL MINE
Anrun produce PE and epoxy coating steel pipes which are the advance products used domestic recently.The pipes are coated double sides and the middle material is strengthen welded steel pipes or crush resistant seamless steel pipes. They are rust and stain resistant, anti-corrosion. And they are much better than plastic pipes in strength and more environment friendly.
The materials of this type pipes are all suitable for special use of coal mine condition. This type products are all in accordance to the standard of MTI81-1988 and CJ/T120-2008. They are antistatic, anticorrosion, safe and have long life for use. They are the best choice instead of traditional material pipes.

Product advantage
Excellent static and burning resistant
PE and epoxy coating with extremely strong adhesive force has excellent static and burning resistant. The surface electric resistant is ≤1×106Ω. For the complex materials, the burn resistant of our pipes is much better than plastic pipes.
Excellent machinical strength
Plastic coating steel pipes for coal mine use strengthen welded or crush resistant steel pipes. It has excellent machinical strength. It is suitable use for rigorous mine condition. It's more safe than other material pipes.
Anti-corrosion, Ageing resistant, Long-life
Densified interior and exterior coating can prevent oxidation. It is anticorrosion to acids, alkalis and salts. Therefore it's very suitable use for fluid transfer with chemical corrosion. The produt has excellent ageing resistant, and the using life is much longer than other material pipes.
Low fluid resistant, High quality and low cost
Interior coating layer resists water scale, knurl etc. Its coefficient of friction and roughness is much lower than traditional steel pipes. The flow capacity can increase more than 30%. Therefore it's high quality and low cost.
Various link method, Convenient but steady
The link method can be groove style, flange style, welded style etc. Conveniently change as requirement.
