Loading Arms are
the best way to transfer large bulk of petroleum and liquefied gas from one
vehicle to another. Loading arms are made with purpose of moving these
substances without any harm to the environment or to the workers working around
it. They provide the best way to do so. Even when toxic materials are
transferred from one tank to another these are the safest way of transferring
these substances.
Top and bottom loading arms are made with the purpose of
transfer of these gases from one tank to another or for rail transport. Both
top and bottom loading arms are made of articulated pipes mainly three of them
the inner the outer and the drop along with swivel joints between them. The
swivel joints are provided to gain flexibility among corners and hard edges.
For dangerous and hazardous materials these loading arms have closed
connectionsthat is the manhole is sealed. The manhole is sealed using a flange
at the top. For all other material which are not dangerous they use an open
connection in which the manhole is nit sealed.Manhole is the part from where
the loading and unloading is done. The bottom loading arm are used mostly for
unloading from the bottom or from the sides of the tank. The bottom loading
arms are usually preferred more over the top Loading Arms.
The loading and unloading from the bottom is considered to be much easier. They
consume less time over top loading arms to load or unload. Also with top
loading arm there is a risk of hazardous situation with workers working under
it but with bottom loading arm the unloading take place on the surface hence
even if the Couse any problem it won’t affect the workers.
Marine loading arms are another loading arm that are largely
used for the transport to or from barge and ships. Since these loading arms
have to withstand changing drafts, tides and other factors they have
significant improvisation over other loading arms making it perfect for marine
locations and at the same time giving longer life to the loading arm and to its
ergonomic operations.
These loading arms have to be carefully designed according
to ones need and environment. One should only get them designed from a very
experienced group so that they know the exact requirement of you. www.hemicoid.com is one such group that
designs and modifies loading arms and are best known in
this business for more information visit us at http://www.hemcoind.com/loading-arms.html
