1, Lining layer flanging are strictly prohibited against, scratch,  if damaged, need repair before installation.

2, During installation, the pipe is strictly prohibited ontology gas cutting and welding.

The main application of steel lined polyurethane chemical pipe:

Steel lining pu wear-resisting pipe has excellent abrasion resistant, acid and alkali resistance, anti-fouling, and that radiation, hydrolysis aging, high elasticity, resistance to mechanical shock etc. overall performance. It can be widely used in electric power, coal, mining, building materials, chemical industry, transport it over coal, ash, slag, molten aluminum, mud and other particles sharpening materials and corrosive media.

Power Industry: Used in thermal power plant ash pipeline, ash pipeline, grey water recycling, water for power plant, the ash of the water and acidic medium conveying system, using polyurethane composite pipe can demonstrate its superiority.

Coal industry: coal washery Dense Medium Separation and long distance cast coal piping system. Sand backfill in coal mining.

Mining Industry: Iron ore pulp, mine ore, tailings conveyor systems, mining flotation system closed loop piping, gold mining in water and sediment transport.

Building materials, chemical industry: steel plant coke conveyor, conveyor aluminum pool of mud, cement conveying pulverized coal conveying corrosive acids, alkalis, salts and solids, both liquids pipeline corrosion, such as oil exploration in the pipeline , ranked silt engineering, urban water supply systems, liquid aluminum pipes, all have a significant effect.
