Burst air awning pole

We were at Morn Hill in July and two air awning poles exploded,Quite a bang

Our daughter's burst in mid summer. The tube had expanded so much it had split the containment sleeve and then failed. Excellent service from the importers who supplied replacement tube and containment sleeve FOC.

It doesn't help that the air poles material are black on some (while the rest of the is sliver) so will absorb more heat in sunlight? I agree that the manufactures would give advice on the pressure to use on hotter days?

We had an air pole burst on our Westfield Carina back in June. Ripped the stitching and made the Awning useless. Tried to contact Westfield with an email but up to now we have never had a reply. Had a problem with our small Kampa awning and to be fair Kampa were all over it, couldn't do enough to help.

It wasn't that hot on Sunday, not compared to summer heat, but the difference from overnight "heat" to daytime might have been a shock to its system. Only a suggestion as I'm no expert.

Makes me wonder if people are over inflating them ? I use the electric pump that came with my Bradcot Aspire which you pre set to the pressure specified in the awnings instructions, once reached it cuts out.

But then again it will depend on the ambient when you use the pump.

If you do that in the cool then in the heat of the day plus the radiant heating of the tube the pressure will inevitably be above what the pump control had set it too.

With these things is it practical to ease off a bit of the pressure and re-pump back so it can be set right in the hotter conditions?

I take your point and agree but I'm sure there is a large margin of safety taken into account as well as the factors you mention when the inflation pressure is set buy the designer/manufacturer ? 

My own awning is only inflated to just over 4 psi, 0.3 bar.  if you use a manual pump without a gauge how do you know what the pressure is?

Surely the manufacturers would have thought this could happen and build something into it so that some of the air could pass out, without bursting the tube.

It would appear Outdoor Revolution did........

Sadly, the others,according to Google, including my Vango Kela, haven't bothered......

My experience as well - excellent support from Kampa when we have needed it.

I always inflate our awning to 3 or 4 psi under the recommended maximum and it's always been fine.  In very hot weather, I nevertheless, keep an eye on it.
