Cross HDPE Ø 110mm with angle 90° used widely today in Europe for angular lines installations of water supply infrastructure and lines for the transport of natural gas. The cross mounted by the method Butt-fusion. A cross enables network branching 90° angle. For welding HDPE pipe with cross used welding heat machinery which makes it possible merger of cross 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.
