Centrifugal cast pipe according to the characteristics of the mold can be divided into four kinds of centrifugal cast pipe

Centrifugal cast pipe according to the characteristics of the mold can
be divided into water-cooled metal centrifugal casting pipe, coating
metal centrifugal casting pipe, resin sand lining centrifugal casting
pipe, sand centrifugal casting pipe.
Water-cooled metal centrifugal
casting pipe, also known as Laward centrifugal casting method, is
characterized by the use of long-flow troughs, which can be cast trough
movement during casting, and can also be cast movement. Due to the use
of special water-cooling devices, the structure is complex, The cost is
high. In addition, due to the chilling effect of water, the cast pipe
tends to appear white, requiring heat treatment, and the cast pipe has
high production efficiency, and is generally used for mass production of
ductile iron tubes of small and medium diameters.
The coating
metal centrifugal casting tube is also called the hot-molded centrifugal
casting tube. The earliest research and development of this kind of
technology was the German company Duker. Its structural feature is that
the metal type has no water jacket, the host does not perform horizontal
movement, and the short flow is used. Groove, the inner surface of the
mold is sprayed with a layer of paint to obtain a white-free, as-cast
centrifugal tube. This machine has a simple structure, low cost,
convenient replacement of the mold, long mold life, and unlimited
diameter of the cast tube. , Can produce gray iron pipe and ductile iron
pipe.
The resin sand lining centrifugal casting pipe features a
layer of sand lining with resin as the binder on the inner surface of
the metal type, which greatly improves the life of the metal type, and
can obtain the as-cast centrifugal tube without white mouth, especially
suitable for Large-diameter ball iron pipe production.
Sand type
centrifugal cast iron straight pipe is suitable for conveying pressure
fluid such as water and gas. The sand cast centrifugal cast iron is made
of gray cast iron.
