Advantages
1) Lower total installed cost – Lightweight product is easier and faster to handle and install and less heavy equipment is required to lift and position pipe. This can result in reduced installation costs.
2) Easy to handle –PP and PP-R are lightweight products making handling and positioning pipe fittings easier and safer. Less heavy equipment is needed to unload, handle product on site and position into trenches.
3) Optimum hydraulic performance – PP-R’s smooth inner skin is resistant to build up and allows optimum hydraulic flow.
4) Chemical resistance – PP-R pipe fittings are resistant to corrosion by aggressive and saline soils and substances typically found in sewage effluent, including most industrial discharges.
5) Sensitive to the environment – The material-efficient production reduces the use of raw materials. PP and PP-R pipe fittings are long life products.
6) Flexibile – PP and PP-R are flexible pipe fittings which have the ability to cope with soil movement and external loading without cracking.
