This bending spring works excellently and makes pipe bending tasks much easier. A tip from me: bend the pipe slightly less than needed at first, then adjust to the desired angle. This makes removing the spring smoother. It's a great tool for professional r...

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
Approvals/Standards
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.
Application areas
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
