Cast Iron Flange
How to purchase cast
iron flange in China? Cast iron flange
means the flange plate made by cast
iron. Actually, not all flanges were
made by cast iron, many flanges were
made by forged steel.
Dandong Foundry has made some
cast iron flanges to Japan. Some were
made by
grey iron, and some by
ductile
iron. Cast iron flanges are not
difficult to produce comparing with
other more complex iron castings, but
when you purchase them in China, you
still need to notice some aspects.
First, as always, material is very
important. The foundries should can do
the tensile strength test in house.
Second, there is no obvious surface and
inside defects. Third, the dimensions
have to be kept, especially for
flatness. You could require the
suppliers to rectify the flatness.
Besides of Dandong Foundry, there are
some good foundries who can make the
cast iron flanges very well. We just
list some as following for your
