Reducer Concentric short spigot HDPE 225x200mm used widely today in Europe for lines installations of water supply infrastructure and lines for the transport of natural gas. The reducer mounted by the method Butt-fusion. Reducer enables joining of two pipes with different diameters respectively of HDPE pipe Ø 225mm and HDPE pipe Ø 200mm. For welding HDPE pipe with reducer used welding heat machinery which makes it possible merger of reducer pages and pipe and through pressure enables their union. Manufactured with European standards, resistant to corrosive materials, high resistance to deformation of land and resistant to pressure up to 16 Bar.
