Steam Coils
Installation and Important Instructions
Steam coils need to be installed
with proper guidelines. You can even take help of a professional
for the best effect.
If you are thinking of
installing steam coils, the guidelines given below can help you.
These guidelines are specifically tailored to meet all your
requirements. However, you still need to get help from an
experienced and qualified professional in order to perform the
installation process. You also need to take help of certain
protective equipment including steel toe boots and safety glasses.
Always remember that steam can be seriously harmful to your body
even at low pressure. The injuries can even be fatal. Hence, make
doubly sure the steam coils system is in ‘off’ mode or all the
components have been isolated prior to starting with the work.
a)
The instructions on the
package:
Make sure you
carefully go through all the instructions given below:
·
All heat craft coils are tested by factory, analyzed and
packaged carefully
· There
may be some possibility of coil damage once these are out of the
factory. Hence, it is very important to analyze
shipping damage when you receive the coils
· Make
note of all missing or damaged items on the freight bill.
b)
Mounting:
It is necessary to
mount steam coils properly. This facilitates prevention of water
hammer. The process will also prevent your coils from freezing and
corrosive elements from being accumulated in the tubes.
c)
Installation:
There are several
steps to follow in order to make sure that you have installed the
steam coils properly. Follow the steps given below:
·
Remove the coil from the shipping package carefully. This will
prevent any damage to the finned surface area. In case, you happen
to damage fins accidentally, you can easily straighten these via
using a good fin comb.
·
It is necessary to clean the coil with coil cleaner available on
the market prior to installation process.
·
Mouth the coil properly in order to make sure that the condensate
drainage is positive.
·
Make sure you maintain proper clearance between the coil as well as
other structures including the filter racks, fan, transition areas
etc.
·
You need to focus on using vacuum breakers on every coil.
Almost all steam traps need a positive type of differential
in pressure in order to provide good force the condensate via
the valve seat. In case, the pressure of coil drops below
atmospheric level the difference of the pressure across the
valve becomes negative. This will stop condensate from
draining. The situation can result in serious damage or coil
failure due to freezing and corrosion.
·
Make sure you trap each coil separately. The differences created in
pressure from every coil can result in bad performance of coil and
any possible damage.
·
You need to focus on providing an air vent for every coil. Make
sure that the coil is at its highest location.
·
All steam supply lines should be drained of condensate.
·
The condensate return piping must be of the same size as the return
connection of the coil from the outlet towards the steam trap.
·
Once you install the coil, you need to pressurize it to 100 psig
with dry nitrogen.
All field brazing and welding need to be performed with the help of
supreme quality materials.
