Tee reduced HDPE Ø 110x75x110mm 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 tee reduced mounted by the method Butt-fusion. Tee enables reduced network branching of HDPE pipe Ø 75 from main pipe HDPE Ø 160. For welding HDPE pipe with tee used welding heat machinery which makes it possible merger of tee 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.
