Large diameter HDPE spiral 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 spiral 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 spiral pipe

· Pipe Weight

The extremely low weight of profiled pipe allows a simpler and faster installation of the HDPE spiral pipes, as in most cases no heavy machinery is necessary for the installation and handling of the HDPE spiral 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 more than 100 years.

· Connection

 HDPE 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 HDPE spiral pipes lengths are 6 meters long..

  

· Transportation

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

· Chemical and Corrosion Resistance

HDPE spiral 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 spiral wound 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.

· Hydraulic Performances of HDPE spiral pipe

   HDPE spiral pipes benefit from a smooth inner wall, providing superior hydraulic performance when compared with rigid materials such as clay or concrete.

· Abrasion Resistant

     HDEP spiral pipes made from Polyethylene or Polypropylene offer far greater abrasion resistance than alternative materials. This graph demonstrates the superior performance of PE spiral 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.
