Outer Bending Spring - 26 x 3.0 mm

The multilayer composite pipe is suitable for cooling and heating applications as well as for sanitary installations.
It was specially developed to withstand a wide range of temperatures and pressures.
The pipes contain the experience of several decades of plastic and aluminum processing.


Advantages

• High temperature and pressure resistance:
• Applications: Temperature max. 95°C, Pressure Max. 10 bar Continuous temperature 70°C over 50 years (DVGW)
• Low thermal expansion
• Absolutely gas-tight thanks to butt-welded aluminum layer
• Pipe color: white
• Certified according to DVGW and EN ISO 21003
• Corrosion-free
• No incrustation thanks to smooth inner pipe surface
• Low noise (soundproofing)
• UV resistance during unprotected storage for at least 6 months
• Resistant to numerous chemicals
• High flexibility and yet dimensionally stable installation, easy and economical processing
• Significantly lower weight than a metal pipe, therefore easier handling

Approvals/Standards

• KVGW W542
• ÖVGW
• KIWA
• KOMO
• SKZ-monitored
• EN ISO 21003
• Approvals in several European countries
• Properties according to DIN 16836

Structure

Polyethylene pipe is extruded and an adhesive agent is applied in a coextrusion process. Then an aluminum strip of 0.2 - 0.8 millimeters thickness is formed around the pipe, longitudinally butt-welded and calibrated to the inner pipe. Then another adhesive layer and a cover layer of polyethylene are extruded.
The weld seam is checked inline during the production process.
The inner diameter of the finished product is checked with a ball.
