SPIRAFLEX corrugated pipes are engineered for high rates of heat exchange. The pipe has a one-of-a-kind helical design which provides unique advantages. When hot water flows through the pipe, it is automatically swirled around the helix of the pipe. This maximizes turbulence in the water which in turn maximizes heat exchange. Additional benefit gained due to helical design is that lime does not deposit on pipe interiors due to continuous swirling of water.

The pipe incorporates numerous beneficial features. Its internal surface area is almost 50% higher and pipe wall is thicker than most conventional pipes. This results in maximization of heat exchange. Despite this, the pipes are exceedingly malleable. They can tolerate high degrees of mechanical load.

Alond with elimination of lime deposits, water being conveyed by pipes is more hygienic since pipe design does not allow dead water to collect in its interiors. The pipes are 100% helium-tested, extremely safe, efficient with guaranteed quality. Custom-made pipes available in SS, thicker walls, extra length pipes etc.

Pipes are used for heat/cold exchange in hot water tanks, geothermal operations.
