Variation of wall thickness at rib.
For those of you who have been following our recent rants
and ramblings in our articles about the prediction of failures
of tanks and chambers, you will probably be saying these
guys just sit there steaming away in their digital world thinking
about things which may, or may not, be happening out there in
the real world.
Your right! We do spend most of our time hiding behind our
monitors, in cyberspace playing with the bugs in our software,
twiddling our thumbs and waiting for inspiration to arrive. But,
sometimes we have interesting days when we are asked to visit
a moulder, or a test house, with our client especially when a
tank is being moulded for the first time or when products are
under test to observe and advise.
On a recent entertaining
day we see operatives
swinging on the tool, hitting
the moulded product with
hammers or prising it out
of the tool with crowbars.
Once these minor physical
issues are resolved and
the operative made to see
the error of their ways, the
recurring question is, has
the polymer been subjected
to the optimal heating and
cooling parameters during the
moulding process?
