Shandong ductile cast iron pipe manufacturers introduced the classification of centrifugal cast pipes. The coating metal centrifugal casting pipe is also called the hot-molded centrifugal casting pipe. The earliest research and development of this process was made by the company Duker (Germany). Its structural features are metal type. Without water jacket, the main machine does not perform horizontal movement. Using a short runner, a layer of paint is sprayed on the inner surface of the mold to obtain an as-cast centrifugal tube with no white mouth. This machine has a simple structure, low manufacturing cost, and convenient replacement of molds. , And long mold life, cast pipe diameter is not limited, 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.
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 above three categories are the latest classification of centrifugal cast pipe. If you want to know more, log in quickly.
4inch Slim Gimbal Led Downlight
Rhein Lighting has developed a line of 4 inch slim gimbal Led Downlight with a junction box. This led gimbal recessed light is IC rated, which is permitted to be in contact with insulations in ceilings.
The 4-inch led gimbal down light use the new generation of LED chips with higher lumen ouput and lower power. 750LM consumes 9 Watts, which equals to 75W incandescent lamp, saving you up to 88% in energy costs.
The ultra-thin gimbal smart downlight is only 0.47 inches and requires as small as 2 inches ceiling spaces, fits various ceilings, and around joists. 5%-100% smooth dimming meets kinds of needs in applications such as kitchen, living room, bedroom, bathroom and common areas in your home or office.
