What are the Different between Cast Iron Valves & Ductile Iron Valves
Customers from different types of industries look for valves of several varieties for their high-demand processes. The valves are found in a wide range of materials for any kind of application that can be imagined. Some of these materials are carbon steel, PVC, stainless steel, Ductile Iron Double Flanged Pipe, and cast iron.
In this blog, we are going to discuss two
of those materials which are ductile iron and cast iron. There has been a vast
argument for choosing the best option ductile & cast iron valves which have
been prevalent for numerous years as everyone is not aware of their
differences.
A Comparison of the valves, by means of cast
iron, and ductile iron is simple as both of these materials just have a few key
differences. So here is an outlined property of both materials as well as the
pros and cons of each.
Cast Iron Valves
Cast Iron or
gray iron is a type of metal that has been used for hundreds of years. It is an
alloy, which is composed of 96% - 98% iron, 2% -4% carbons, and a trace amount
of silicone. It has an impressive tolerance to temperature with some cast iron is
capable of handling temperatures more than 2100F (1150C).
In this case, the
pressure, strength of cast iron mainly depends on the pressure class. The two
most ordinary ones are class 125 and class 250. At less excessive temperatures,
class 123 cast iron flanges are rated for a pressure level of 150 & 200
psi. The class 250 cast iron is a little bit tougher as well as has pressure
ratings from 300 to 500 psi.
These pressures can be different according
to the type of the end. Cast iron is very stronger and will usually not have
any damages even after experiencing strong vibrations. The major drawback of cast iron valves is that they are not
at all ductile. Bending virtually will cause cracking of the cast iron as well
as it will become much useless.
One incredible quality of cast iron is that
it not that expensive. Cast iron is the most economical choice among the metal,
which makes it a great option for people looking for budget-friendly options.
Ductile Iron Valves
Ductile iron
has wonderful tensile strength, corrosion resistance & yield strength. Similar
to cast iron, ductile iron does not break when it is bent therefore it is much
more appropriate for high-demand applications. Ductile iron is a sturdy and
reliable material for fitting, pipes & valves. Ductile Iron is relatively
more on the expensive side than cast iron due to its more complicated chemical
makeup. If your application requires a tougher material, then you may need to
spend relatively more.
Deeper
Comparison
Now that you
have learned and comprehend both of these materials, now we have made a deeper
breakdown of the differences among both of these metals. This will give you a more
clear and easier understanding.
Durability
The Cast iron
is very strong and can handle higher pressure than any plastic. While the rated
pressure of a cast iron valve or pipe surpass, it can get creaked or bent. Cast
iron has zero ductility which makes it enormously rigid and can get creaked if
it is bent. During this period, cast iron can also attract corrosion and it
needs regular maintenance to keep the valves clear of any rust.
Ductile iron has extraordinary integrity of
structure and can handle high temperatures & pressures without flinching.
This is due to the ductile nature which makes the material much less possible
to get bent or cracked. Ductile iron will additionally attract rust over the
passing of time.
Ease of Installation
Both cast and
ductile iron valves provide the users with a wide range of installation
options. The cast iron valves are bolted using flanges as well as the same is
for ductile iron. Welding is not suggested.
