Tubing: We use the
"easi-fit" pex-al-pex tubing because of its strength, flexibility and form
stability, which leads to a good insulation of strong pipework with a 100% oxygen barrier
and smooth stable bends (that won't kink or collapse during screeding)
 
Properties of Easi-fit Pipe
Form
stable:
Easi-fit Pipe can be easily bent or shaped by hand and still retains its shape
- no spring back. Pipe benders and springs are available for tighter bends. |
|
Cross
Linked Structure:
The sonically welded Aluminium pipe is bonded internally and externally to fully
cross-linked PE pipes, giving Easi-fit Pipe added strength compared to plastic pipes. |
|
Working
Life:
When installed according to our manual Easi-fit Pipe has a working life in excess of
50 years. |
|
100%
Oxygen Barrier:
The welded aluminium layer forms a complete oxygen barrier to protect any ferrous
metal in the system e.g. pump, boiler, radiator. |
|
Hygiene:
The internal polyethylene layer is so smooth that scale or fur does not build up,
there is no risk of micro-organism growth so Easi-fit Pipe can be used for drinking water
systems. |
