Kampa air exploded

Anyone heard of a Bradcot air awning going pop? IIRC the maximum inflation pressure is 35 kpi, just over 5psi and I think I'm right in saying they made using marine grade valves and materials? 

I always use the electric pump with mine which can be pre set to cut out at the required pressure.

Our Outdoor Revolution has air pressure release valves if the beams go over pressure ,  which may, or may not , help ?

Ref the increase in temp relative to pressure, I assume that would be air temperature.  My thoughts work along the line that any black object will heat up in the sun to a temperature that almost melt the rubber tube causing failure, rather than over inflating the tube.

We have been out for the day and noticed an awning "colapsed"on a caravan a couple of pitches from us ,our neighbour said there was a big bang about 1pm and the awning just deflated

It has since been removed

could be just a theory though? 

Amazing, after all those years to be able to narrow it down to the hour 

well know fact that it all started on a club site.

And he said let there be light, and there was and it was good

Our daughter had an air which not only burst but split the containing sleeve beyond repair.

I can fully understand the above, but I have difficulty in understanding how the pressure tube can burst without the outer layers bursting too.

To help people’s understanding, there are normally three components to air beams.

The innermost one is airtight, not rubber as suggested on this thread, but a plastic, which in itself is far too weak to survive without containment. Our Kampa tubes are, I’m told, made of the same plastic which the Millenium dome is made of. This is used because of its long life expectancy.  Kampa sell, very cheaply, puncture repair kits similar to bicycle ones, but with much bigger patches/tape. We’ve never had cause to use ours.

Surrounding and containing the inner tubes is a zipped on cover. This stops the inner tube from expanding beyond it. It’s strong and should be able to withstand the expansion of the inner tube, up to its design limit.

Forming a loser fit around the pressure cover, is a heavy duty protective sleeve, to resist abrasion etc.

Contrary to some views above, we’ve always found Kampa’s after sales support to be exemplary. The advice, on this thread, that they’ve been taken over, may well have reduced standards. I don’t know.

I think that there may be two lessons in this thread;

Watch out for overpressure.

Buy a cheap puncture repair kit.

And if Darren is still working for Kampa. Then try to talk to him, via Customer Services. He is/was in their technical Dept.

I don't think a repair patch would have been much use really. 

If repair patches work on car and bicycle tubes. And Kampa sell them. Why don’t you think that they will work, when their use is widespread?
