DN3000 HDPE Spiral Profile Pipe

Quantity:

      HDPE/PP profile spiral wound pipe systems with various stiffness classes which are designed for non-pressure applications. It is made from High Density Polyethylene (HDPE) or PP . The diameter of HDPE/PP Krah pipe is from DN/ID300mm to DN/ID 4000mm. The ring stiffness is SN2, SN4, SN8, SN16 or according to customer requirements.


ADVANTAGES of HDPE/PP Krah Pipe

· Pipe Weight

The extremely low weight of profiled pipe allows a simpler and faster installation of the pipes, as in most cases no heavy machinery is necessary for the installation and handling of the HDPE/PP profile pipes. Most of the handling can be done by an excavator on-site.

· Enviromental and long life time

  Low investment cost and a service life over 100 years.

· Connection

  Spiral profile pipe do not require large butt welding machines as they are joined either by rubber ring joint or electro-fusion.

· Installation

The installation time is faster than other materials as the standard pipe lengths are 6 meters long..

· Transportation

As it is possible to nest these profile spiral pipes, transportation costs can be reduced.


· Chemical and Corrosion Resistance

Profile pipe and fittings are made of the same material and jointed to one homogenous piece. Not even connections between the pieces pose a weak spot in the pipe system as they are joined by a rubber ring or electro-fusion water tight joint.


· Homogenous Pipeline

HDPE/PP profile pipe and fittings are made of the same material and jointed to one homogenous piece. Not even connections between the pieces pose a weak spot in the piping as they are joined by a rubber ring or electro-fusion water tight joint.


· Effective Roughness

Due to its low roughness as shown in the above graph there is almost no accumulation on the pipe bottom and profiled pipe have the ability to self purify. Low roughness has an important economic advantage as maintenance expenditure is kept to a minimum. Due to the low roughness the hydraulic properties are improved and smaller diameters are required compared to conventional pipe materials with the same flow rate. profiled pipe convey flows up to 17% greater than concrete pipes, and up to 60% better than corrugated steel pipes.


· Abrasion Resistant

  Polyethylene or PP pipes are among the most abrasion resistant pipes. This has been tested in the Darmstadt procedure and the results are shown in the diagram above and support the quality of polyethylene and polypropylene pipes.


· Resistant to Micro Organisms

Polyethylene is not nutrient media for bacteria, fungi and spores, so that the material is resistant to all forms of microbial attack as well as both sulphurous acid and sulphates.
