The Challenge - Applications at a Glance
High Capacity Drip Legs
When Velan Engineering looked at Power Station applications,
they realized that many of the steam lines went to very high pressures
and temperatures, and needed to discharge tremendously high startup
loads. Due to the way systems were operated, a thermostatic steam
trap did not have the necessary capacity that was required, and the capacities
were so great, the traps that were able to handle the startup load were extremely
inefficient on the hot running load. Therefore, Velan deduced that
the market needed a steam trap that could pass tremendously high startup loads,
but also turn itself down to pass small running loads. In 1947, as
it is today, very few manufacturers even attempted to manufacture a product
for this application because it is so specialized.
High Capacity Forced Heat
Applications
When Velan Engineering looked at Petrochemical applications,
they realized that many of the steam traps that were being used on
large heat exchangers and reboilers were extremely large and required
large amounts of maintenance. In certain plants there were some applications
that had very high startup capacities, high running loads, at very
high pressures and temperatures. In 1947, as it is today, very few manufacturers
even attempt to manufacture a product for these applications because
it is so specialized.
