For more than 30 years, Polypropylene Random Copolymer (PP-R) has been applied successfully
for hot and cold water applications in countries worldwide. The combination of properties such
as resistance to internal pressure, flexibility and impact have made PP-R the material of choice for
a safe and reliable long-lasting installations. No wonder that PP-R has been continuously replacing
traditional materials like copper and galvanized steel over the last decades.

Benefits of PP-R:
• Service life according to tests performed under ISO 15874
• No contact corrosion when exposed to iron particles
• Taste and odor neutral
• Bacteriologically neutral
• Fast and easy installation
• Entire plastic systems available
• Good chemical resistance
• Low tendency to incrustation


Fusion Instructions:
1,Mark the pipe
Mark the pipe for depth of penetration into the heater bush and fitting (see table). The mark must remain visible under heating and joining. 
2,Heat pipe and fitting
Push the pipe and the fitting into the heating tools. Once pipe and fitting are hot (after the correct time), pull out pipe and fitting very slowly.
3,Joint pipe and fitting
Joint the pipe & the fitting and push the pipe until it reaches the mark (that has to stay outside).
During the jointing time the welded part of pipe and fitting must remain fix, without any rotation.
During the cooling time, the welded part of pipe and fitting can be adjusted until cold. 
4,Fusion inspectoin
Fusion inspection. The outer fusion seam must be inspected. The seam must be present all around the pipe.
