For special pressure class and stiffness grade can be designed especially
-DIA. DN100-4000mm Specification of RPM pipe
PARAMETER OF RPM
Note: The serial parameter listed in the above table is only applicable for water supply or drainage.
Normally the pipe is not larger than DN400 doesn't add sand.
1. Water supply project
-construction for urban and town water supply system
-modification for urban and town pre-existing water supply pipe
2. Drainage project
-sewers in urban area
-industrial drainage pipe
-Other drain pipes. RPM pipe can be considered to be used for drainage pipe for rain water and sewage in urban and towns , factory and mine, airport, seaport of coastal area or area reclaimed from the sea, because RPM pipe has the following advantage: sulfuric & alkali proof, occupy less area, heavy traffic, easy for transportation and less excavation and backfill.
3. Water conservancy and power project
-Culvert project. RPM pipe can be used for feeding and drain the culvert on the cross point of the dams, channels and roads.
-Inverted siphon and
-Strengthen of the pre-existing culvert in the reservoir.
-Pressure pipe in hydropower station on mountainous regions.
-Sea water cooling pipe of power station
- Conveying for corrosive fluid. For all industrial pipes which convey corrosive liquid and gas, such as the pipe needs to be of large diameter and anti-corrosive metal material, under this condition, RPM pipe is better.
-Pipe for petroleum industry. Used for the conveying of crude oil and natural gas, and the water return of oil field.
-Offshore construction pipe.
-Heat supply pipe. RPM pipe is excellent heat insulator, good property of insulation. It is suitable for conveying vapor and geothermal water etc.
-Ventilation and air supply pipe. It is used for large scale factory and mine, especially for ventilation of underground works. In large scale hotels, it can be used as the air supply pipe of central air-conditioning system.
