Product Details
Anti-corrosion rubber lined pipe slurry mining Dn25-Dn2000 tailings pipeline
Product Description:
Steel and rubber composite pipe is a kind of mixed slurry pipe which uses steel or hard material as the outside pipe framework, and rubber as the liner. Steel is hard and rubber is wear-resistant, anticorrosive and temperature-resistant, therefore this rubber-lined steel pipe combines the advantagesof steel and rubber. The physical and chemical performances of rubber reduce the effect oftransferred media on the outside structure, such as shock and corrosion. So the pipeline obtains theperformance of high strength, high wear-resistance, high anti-corrosion and high temperatureresistance and therefore prolongs the lifetime of pipeline and reduces cost.slurry pipeline or slurry pipes are used in mining to transport mineral concentrate from a mineralprocessing plant near a mine.

Characteristic Feature:
Wear resistance: more than 10 times the service life of ordinary steel pipes
The lining adopts special formula: strong chemical performance, can transport strong dirt medium
Low cost: more than 50% cheaper compared with cast iron pipeline
Adaptability: the size of the pipe is not limited, any shape can be lined with rubber composite
High comprehensive benefit: long life, shorten the replacement and maintenance cycle, save labor cost
