Watertech PPRC Pipes & Fittings

Watertech PPRC Pipes & Fittings are an absolute and perfect solution for supply of hot and cold water and other liquids. PPRC is used in applications of pressured hot and cold water delivery as well as under floor heating in all modern residential apartments, housing & societies, commercial buildings and industries for their high resistance to high temperature and pressure.
Watertech PPRC pipes are made from Polypropylene Random Copolymer which is highly resistant against heat and chemical affects etc and a 100% certified food grade materials. Watertech PPRC pipes are made of 100% pure of imported raw materials while using the latest and advanced high speed PPRC extrusion lines first installed unit in KPK province.

Welding – Getting Started:

01. Cut the pipe at right angle with a cutter.
02. Mark off the welding depth at the pipe end.
03. Simultaneously heat the ends of both pipe and fittings as per recommended heating time.
04. Push the pipe end into the fitting and ensure its alignment of assembly within the specified time period.

Fusion Data For PPRC

Outer Diameter Average Heating Time Average Working Time (Max) Average Cooling Time (Max)
20 5 4 2
25 7 4 2
32 8 6 4
40 12 6 4
50 18 6 4
63 4 8 6
75 30 8 6
90 40 8 6
