Wholesale Price DN200mm to DN4000mm Double Wall Corrugated Drainage Underground HDPE Krah Pipe for Philippines
Krah pipe is a kind of special-shaped pipe with smooth inner wall and spiral strengthening outer wall. Spigot and socket Krah pipe normally divided into B type and C type, which are green and flexible, use high density polyethylene as raw material, produced by filament winding process in the states of hot-melt, gradually cooled by means of rolling air cooling and spraying in thermal state and before demolding. It is available for a wide range of diameters from 300 mm to 3000 mm, can be connected by socket-joint. Krah pipe has all the features: high strength, light weight, corrosion resistance, no leakage, good sealing and easy construction etc., be widely used in drainage projects.

1. Smooth inner wall, low friction resistance and large flow can promote efficient flow and minimize friction losses.
2. Variety of diameters and wall thicknesses allows for selection based on specific flow requirements and pressure ratings. 
Advantages:
① Long service life: The normal service life can reach more than 50 years.
② Excellent corrosion resistance: except for a few strong oxidants, it can withstand corrosion from various chemical media; Good impermeability.
③ Excellent wear resistance: Compared with the wear resistance of steel pipes, the resistance is more than 4 times that of steel pipes.
④ Good low temperature resistance and impact resistance: good toughness and high impact strength; Low brittleness temperature, range of use -60 ℃ to 60 ℃.
⑤ Good construction performance: The pipeline is lightweight, easy and fast to construct, reliable to connect, and has a low overall project cost.
⑥ Good flexibility: The pipeline has good flexibility, can be moderately bent, and has good resistance to uneven settlement.
⑦ Low water flow resistance: The inner surface of the pipe is smooth, with low fluid resistance, which can reduce pressure loss and water transmission energy consumption in the pipeline.
