Standards/approvals:
• DIN EN ISO 15874
• DVGW (German Association for Gas and Water Applications)
• Corresponds to the KTW recommendation of the Federal Environmental Agency (UBA)

Characteristics:
• Good resistance to chemicals
• Weather resistant
• Excellent processing

Joining methods:
• Heating element socket welding
• Heating coil socket welding
• Heating element butt welding

 








PP-RCT PIPE SYSTEMS



A new generation of material, thanks to its structure, pipes and fittings can be produced with higher hydraulic capacity or with higher compressive strength. This means that - for the same application case - if the pipes are produced with thinner walls, they have higher flow capacity with a consistent outer diameter. In contrast, PP-RCT pipe can be subject to higher pressures than the previous PP-R pipes, with the same outer diameter and the same wall thickness.

Material:

Polypropylene-random-copolymer with a modified crystalline structure and increased temperature resistance, RAL 6024 traffic green.

Standards/approvals:
• DIN EN ISO 15874
• DIN 8077/ 8078
• Corresponds to the KTW recommendation of the Federal Health Agency (BGA).
• WRAS
• NSF

Characteristics:
• Good resistance to chemicals
• Weather-resistant
• Excellent processing capability

Jointing methods:
• Socketfusion
• Electrofusion
• Buttfusion
