Ductile iron pipe usage in snow making sphere for ski resorts

 

 

In the modern world in rapidly developing circumstances of sport-entertainment industry, the usage of artificial snow-making devices and the accessibility of ski slopes is a necessary factor for any ski resort.

The main condition of normal snow making process is a reliable pipeline system for water supply that is confirmed with all the requires of highland systems under big pressure.

 For the artificial snow making system we offer socket pipes made of ductile iron pipes with the “RJ” type of connection (DN 80-500mm). The leak tightness abut is reached by the compression of the resin gasket that has already recommended itself as a reliable connection in water supply systems. The materials to be used during the gasket making are to be  under a very professional and serious control to guarantee all the best characteristics during all life service of the pipes. In order to protect the pipes inside they are covered with cement mortar lining according to ISO 4179 standard.  Outside the pipes are covered with metal zinc and bituminous varnish according to the standard ISO 8179.

DIP  advantages:

-         

  • Strong material and flexible types of connection
  • High pressure resisting 
  • Simple and fast assembling without welding (to 400 meters per day) 
  • Angular deflection (to 5 degrees)  
  • Certificated quality according to ISO, EN standards  
  • Lifelong service is more than 100 years
  • Norms and specifications for design process and ductile iron pipeline RJ joint in snow making sphere
