Use of Corrosion Inhibitors<br />
Corrosion of metals is a hazard in<br />
all installations therefore it is<br />
essential that possible causes of<br />
corrosion are kept to an absolute<br />
minimum.<br />
Oxygen will almost always be<br />
present in any system as it can<br />
enter through a variety of points<br />
such as open header tanks, threaded<br />
joints, valves, pumps and above the<br />
bleed point on a radiator.<br />
To provide maximum system<br />
protection independent of pipe<br />
material, all heating circuits should<br />
be protected by an inhibitor.<br />
Hep 2 O ® Barrier Pipe incorporates an<br />
additional oxygen barrier to reduce<br />
ingress of oxygen through the pipe<br />
wall.<br />
Fernox MB1 and GE Betz Sentinel<br />
Inhibitors have been tested and<br />
are suitable for use with Hep 2 O ® .<br />
Handling and Storage<br />
Hep 2 O ® is an extremely tough and<br />
durable system. However, as with<br />
all materials some care is required<br />
to ensure damage is not incurred<br />
during storage or installation which<br />
may impair its ultimate performance.<br />
Straight lengths of Hep 2 O ® pipes<br />
may be laid flat or stacked vertically.<br />
Coils may be laid on their side or<br />
edge. Both are lightweight and easy<br />
to carry and handle.<br />
Pipe and fittings wherever possible<br />
should be stored in their original<br />
packaging until ready for use. This<br />
ensures protection from ultra-violet<br />
light and will reduce the risk of<br />
contamination.<br />
Spare grab wedges and ‘O’ rings<br />
should not be carried loose<br />
amongst other fittings or tools<br />
where they may be damaged. They<br />
should be kept in their original<br />
packaging or in a separate container<br />
which will protect them.<br />
Hep 2 O ® should be protected from<br />
contact with petroleum and oil<br />
derivatives, fluxes and other agents<br />
that may damage fittings or<br />
components.<br />
When carrying or installing<br />
Hep 2 O ® pipe, care should be taken<br />
to avoid dragging the pipe along the<br />
ground or damaging the pipe on<br />
other surfaces such as walls.<br />
When feeding pipe through holes in<br />
walls and brickwork the pipe end<br />
should be taped over, or<br />
alternatively, the red end cap<br />
included in the pipe coil should be<br />
used to prevent damage to the<br />
jointing surface and debris entering<br />
the pipe.<br />
Care should be taken to avoid<br />
kinking the pipe during installation.<br />
Hep 2 O ® Straight Coiled pipe is easy to<br />
carry and handle<br />
