Abstract:
Pipe fittings are very important parts which are
essentially required for the development of related
industries as well as improvement of our daily life.
They have many uses including changing directions
and prolonging the transport of air or liquid through
fitted pipes in a wide range of industrial fields and
even kitchen plumbing in a house.
In recent years, high-pressure pipe fittings are much
in demand but ordinary cast products have difficulties
meeting the requirements. Therefore, the consumption
of malleable cast iron, best suiting the iron casting
for the pipe fittings, has been on an increase year by
year, with black heart malleable cast iron proved to be
most suiting among the materials.
