The full name of pipe mould is centrifugal ductile iron pipe mould,
which is used for casting ductile iron pipes. It’s large equipment
for producing ductile iron pipes on the machine of centrifugal
pipe-casting. In the manufacturing process of ductile iron pipe,
pipe mould is mounted on a centrifugal casting machine with
high-speed rotation to cast iron pipe. It belongs to the industrial
Owing to poor working conditions, such as high-speed rotation,
great centrifugal force, under alternating stress and cold outside
and hot inside in the process of using pipe mould, the die forging
quality is directly related to its life -- numbers of extubation.
Our company provide alloy steel pipe mould with excellent mechanism
performance, which can have a variety of special properties, such
as wear resistance, high and low temperature resistance, corrosion
resistance and so on.
The materials: 21CrMo10, 20CrMo, 30CrMo, 42CrMo, 35CrMo, etc. are
mostly used for the forged centrifugal casting pipe mould. It is
made from forging, normalizing, formed with quenching and tempering
Different ways of machining process are followed in light of
different specifications of the pipe mould, in order to lower its
A) for small-caliber pipe mould, using solid forgings for the
blank, and adopting deep-hole drilling, boring hole for machining.
B) for medium-caliber pipe mould, using solid forgings for the
blank, employing technological methods of jacking and boring hole.
C) for large-caliber pipe mould, using hollow forgings, ability to
complete all the machining for outer circle of the inner hole
disposably. It not only improves the production efficiency, but
also can obtain good coaxiality.
Production process: steel ingot -- forging -- rough machining -- UT
-- boring -- QT -- the 2nd rough machining -- hole enlarging --
aging -- lightly boring -- oiling -- packaging -- delivery
It is widely used in the city and water conservancy construction,
such as water supply and drainage pipelines, gas pipes, high
pressure boiler tubes, oil pipelines and so on.
The application of machine: tube drawing machine
