Spiral Pipes. Lightweight. Our pipes are tough yet lightweight enough to be easily carried by two people, thus reducing transport costs and time. Roads can be reinstated within hours.

Its lightweight property is ideal for use in highly inaccessible areas by big trucks such as hilly slopes as the pipes can be manually brought up the hill easily. High Ring Stiffness. The superior material properties of HDPE that outlast traditional concrete and metal pipes, is the material of choice in the modern construction environment. Floats Rubbish Chutes.

Spiral HDPE Pipe. Spiralpipe, are produced by first winding an inner liner on to a mandrel.

This includes both the spigot and socket of the pipe, and in a second operation, a rectangular hollow profile is fused (welded) onto the outside of the inner liner. This produces a lightweight pipe with high ring stiffness. By varying the inner liner thickness, and the profile spacing and size, pipes with different ring stiffness is produced.

HDPE Spiral Pipe. HDPE pipes can withstand hot soils, sewer gasses, acidic and alkaline run off making them highly suitable for all types of applications.

You save on maintenance too due to its high resistance to corrosion and chemicals. With such significant benefits and cost savings, HDPE spiral pipes are a smarter choice compared to concrete and metal pipes for storm water drainage. Floats Rubbish Chutes.

HDPE Spiral Pipe. Conventional non spiral corrugated pipes, however, are made up of individual ring that will lock in all the impact energy onto only one size ring.

Thus, the impact energy is trapped and localized onto that single ring and causes high levels of stress that compromises the integrity of the individual ring. Floats Rubbish Chutes.

Why Tomher Spiral Rib Structure is Stronger. The spiral structure of our spiral and sewer pipes enables impact loading to be dispersed over a wider area by guiding the shock wave to propagate through the spiral rib to both ends of the pipe to spread the impact energy over the entire length of the spiral pipe.

The impact force is spread out and channeled to both ends of the pipe so that the peak force value is below the breaking force. That's why our spiral and sewer pipes are stronger and can withstand tough conditions. Floats Rubbish Chutes.
