Quality of valve body material
Thread Content
If the valve body material is carbon steel, is it better to use forgings or castings? Caliber 100 and below
Forged parts are definitely superior to cast parts, but it also depends on the specific operating conditions. When making a choice, the most suitable option is generally selected, rather than the best one.
It depends on the actual situation; it’s up to various factors in the environment you use it in
Generally speaking, forgings are better than castings!
Choose only the correct or suitable option; don’t go for the most expensive or best one—just what meets the usage requirements is sufficient! ! !
Forgings under 2 inches; castings 2 inches and above, including 2 inches
Generally speaking, forgings are superior to castings; however, the choice between them depends on specific requirements. Typically, castings are used for diameters of DN50 and above, while forgings are chosen for diameters below DN50
In most cases, it’s definitely the forging that’s the issue; it depends on the operating conditions
It must be well-forged, right? Materials have better density, weldability, compressive strength, and mechanical properties compared to cast materials; however, forgings cannot be used to create products with complex structures, as they are typically used to produce sheets, columns, rings, and other blanks with simple geometries. The cost is much higher than that of casting. As for valves, it is not necessarily the case that only those below 2` are made as forgings. Large-diameter valves can also be forged.
The advantage of forgings over castings is their better quality, while the disadvantage is their higher price!
