Durable and sustainable – the ALPINAL pipe system

Water is precious and the cautious use of this valuable resource is essential. Even when it comes to pipelines for its snowmaking systems, TechnoAlpin insists on the highest quality standards in order to avoid any kind of loss. The ALPINAL system is a complete system made from ductile iron pipes that covers all pipeline construction requirements. Developed specifically for use in challenging conditions, this system is the ideal solution for water supplies in mountainous areas and at high pressures.

Simple laying – high stability
 

On alpine terrain, a pipe system has to withstand extreme conditions. At the same time, it must be possible to carry out the work quickly, easily and safely. The ALPINAL system combines high tensile strength and high operating pressures with simple laying. Thanks to the push-fit socket technology, the pipes can be laid easily and quickly. For this purpose, the ALPINAL system uses NOVO-SIT and TIS-K restrained socket joints, which combine a number of advantages.

• They are rated for very high pressures of up to 100 bar.
• No concrete thrust blocks are required.
• Assembly is quick, easy and can be done whatever the weather.
• Even in inhospitable mountain conditions, the excavated material can be used to backfill the pipe trench; this is environmentally friendly and cost-effective.
• High angularity (3°) of the push-fit socket joint. This reduces the number of fittings, and cuts down the excavation and blasting work required.

Revolutionary coating
 

The coating is responsible for 84% of the product’s longevity. The Zinalium coating system consists of a zinc-aluminum alloy (ZnAl 85-15), which generally has twice the layer thickness of that required by the standard (400 g/m²). The AQUACOAT water-based acrylic protective layer is applied on top.
 

The two-phase structure (aluminum and zinc) increases the resistance of the coating and extends its life limit even in aggressive soils. Any minor damage is rectified by the self-repairing effect of the protective layer. The Zinalium coating system is free from solvents and bisphenol A. The use of this harmful substance is increasingly restricted by legal regulations.
 

The pipes are produced in Europe by PAM Saint Gobain, the leading supplier of ductile pipeline systems. Just like TechnoAlpin, Saint Gobain attaches great importance to the sustainable development of its products as well as to durability through the highest quality.
 

These advantages are convincing more and more customers around the globe. TechnoAlpin laid over 230 kilometers of ALPINAL pipes in 2022 alone.
