Reducing tees are manufactured from black PE100 high-density polyethylene compound. The PE100 compound is a homogeneous mixture of polyethylene, antioxidants, pigments, and UV radiation stabilizers.
The PE100 raw material complies with SR ISO 4427-1 and SR EN 12201-1 standards.
Manufacturing
Reducing tees are produced by welding a reduction/assembly of reductions directly onto a large diameter pipe (see png sketch).
Reference Standard
SR EN 12201-3: Plastic piping systems for water supply, service connections, and pressure drainage systems – Polyethylene (PE). Part 3: Fittings.
Usage
In potable water supply networks with an operating pressure of PN 9.6 bar, installed underground.
The service life is 50 years, corresponding to a usage temperature of 20°C and a working pressure equal to or less than the PN for which the fitting was manufactured.
Joining Method
– By butt welding with fittings/pipes of the same SDR.
– By electrofusion.
