Liaocheng Hongfu Pipe Industry Analysis Centrifugal cast pipe origin and classification The world's first centrifugal cast pipe machine was manufactured in 1849 by the British man Andrew Shank, and in 1852 cast a length of 3 Centrifugal cast iron pipe with a diameter of 75 mm. The United States, Canada, France, Japan, and Germany respectively produced centrifugal cast pipes in 1922, 1923, 1928, 1940, and 1945. Centrifugal cast pipes can be divided into water-cooled metal centrifugal cast pipes according to the characteristics of the cast molds. Centrifugal cast pipe, resin sand lining centrifugal cast pipe, sand type centrifugal cast 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.
Liaocheng Hongfu Pipe Co., Ltd. is a professional sales ductile iron pipe, seamless steel pipe, high pressure boiler pipe, high pressure alloy pipe, square pipe manufacturers, to understand the latest ductile iron pipe prices, seamless steel pipe prices, high pressure boiler pipe prices on the advice .
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.
