Forge and casting pipe fitting and flange

Casting is the process where metal is heated until molten. While in the molten or liquid state it is poured into a mold or vessel to create a desired shape.
it can be used in pipe fitting, flange and Customized parts.
Forging is the application of thermal and mechanical energy to steel billets or ingots to cause the material to change shape while in a solid state. it was
used in ASME B16.11, ASME B16.5 flanges
Why use castings?

The advantages of casting include:
No real upper size limit in casting weight
Large range of alloy choices
As forgings remain solid, custom alloys are far more difficult to get into production whereas with casting, alloys including Chrome, Nickel and Moly can be added at the molten stage.
Tooling is often less expensive than forge dies
Smaller production “runs” required
Complicated/complex parts are no problem
For general GET as well as large and complex components - casting is a fantastic method of manufacture.

Why use forgings?

Forged steel is generally stronger and more reliable than castings and plate steel due to the fact that the grain flows of the steel are altered, conforming to the shape of the part.
The advantages of forging include:
Generally tougher than alternatives
Will handle impact better than castings
The nature of forging excludes the occurence of porosity, shrinkage, cavities and cold pour issues.
The tight grain structure of forgings making it mechanically strong. There is less need for expensive alloys to attain high strength components.
The tight grain structure offers great wear resistance without the need to make products “superhard” We have found that, on a blank HRC 38-42 forged grinder insert wear/wash is about the same as a high alloy HRC 46-50 cast grinder insert. The difference being a HRC 46-50 casting does not have the ductility to handle high impact grinding.
