Metal Reinforced Polyethylene (PE) Spirally Corrugated Pipe
Process:
Metal Reinforced Polyethylene (PE) Spirally Corrugated Pipe is a new kind of double walled spirally corrugated pipe. It uses the HDPE as basic material and the steel strap spiraled as the supporting part, which is spiraled to corrugated wall structure.

Properties:
1. Yellow inner surface, guarantee for the quality
HTIDC Metal Reinforced Polyethylene (PE) Spirally Corrugated Pipe use piping standard virgin polyethylene as raw material, the inner layer is light yellow; it doesn't use any recycled material and other unnecessary additives.
2. Zinc coated metal sheet, strong bonding, and preventing layering
HTIDC Metal Reinforced Polyethylene (PE) Spirally Corrugated Pipe uses Zinc coated metal strap as a reinforced part, it has anti-corrosion property, HTIDC does not use ordinary cold-rolled steel sheets, which can easily be affected by corrosion, poor in binding and can be separated to polyethylene as a layer.
3. Super Corrosion and Abrasion Resistance
Piping class polyethylene material as raw material is used for Metal Reinforced Polyethylene (PE) Spirally Corrugated Pipe, which is a kind of crystal un-polarity material, so HTIDC pipe has high resistance against corrosion and abrasion. So it is very stable to various kind of chemical material and electrochemical corrosion. It has longer lifespan as well.
4. Smoother inner will and higher transportation capacity
The roughness coefficient of Metal Reinforced Polyethylene (PE) Spirally Corrugated Pipe inner wall just is n=0.009, It can increase the transportation capacity to 30% than concrete pipe under the same condition.
5. Lighter weight and easier installation
The structure of Metal Reinforced Polyethylene (PE) Spirally Corrugated Pipe is hollow wave form, it is lighter in weight and easier installation features compared to concrete pipe, and good welding quality can be assured because of patented new welding technology.
6. More flexible pipe, resist to unequal settlement
Metal Reinforced Polyethylene (PE) Spirally Corrugated Pipe possesses the characteristics of both rigidity and flexibility, when under pressure, the pipe and backfill soil can resist to external load and reasonable uneven settlements of soil. Combined with the advantages of the electric-fusion belt welding method and the patented technology of welding, which can ensure the safety of the welded connection.
