Guaranteed water supply on site.
Leaking water lines which go unnoticed are a recurring problem and can result in large quantities of water seeping into the ground. This volume of water can constitute a major risk as it can cause a landslide. This danger is also present when supplying water to snow-making systems.
Hose assemblies need regular maintenance. The recommendation given in DIN 20066 is that hoses should be replaced after six years at the latest. "Even when stored correctly and operated with safe working loads, hoses and hose assemblies are subject to a natural ageing process. Their service life is therefore limited.... The service life of a hose assembly including any time spent in storage should not exceed six years", it says in DIN 20066. Hoses used in snow-making systems which lead from the hydrant in the pit to the snow gun must be inspected regularly and installed in such a way as to facilitate their replacement. If the branches from the main lines to the pits in the ground are made of rubber, however, then regular inspections and any replacements will always involve extensive digging work. In order to rule out this problem from the outset, TechnoAlpin has been insisting on galvanized fittings and pipes for high-pressure systems for years.
"We are well aware that there are cheaper solutions for the branches from the main line. But our top priority is the long-term safety and reliability of the water supply. We don't take any risks in this regard", said Markus Pfeifer, head of plant engineering at TechnoAlpin, explaining why the company uses high-quality materials. "It is more complex and costly to install the fittings than the hoses but this additional investment pays off in the long run when no more digging is required - not to mention the safety of the system", continued Pfeifer.
TechnoAlpin works with galvanized 3000 series fittings and A-shaped pieces for short rises for the link between the connection point in the pit and the main line. Cast iron T-fittings with an 80 cast iron pipeline and hydrant feet are installed at longer rises. These steel parts last much longer than hose assemblies, increasing reliability and minimizing additional work.
