Description

This product is suitable for project-driven equipment parts that require a hollow forged form but do not match standard sleeve, cylinder, or tube dimensions. The forging can be developed around the drawing to control outer diameter, inner diameter, wall thickness, length, and special features. It is an effective solution for OEM and EPC customers who need hollow preforms for further machining into specialized industrial components.  For custom hollow forgings, the main procurement value lies in being able to define bore size, outer contour, wall thickness, and machining allowance directly from the drawing rather than adapting a standard tube or sleeve. This makes the product especially useful for engineered equipment parts where the forging must already approximate the final structure before detailed machining begins. Additional services such as rough turning, heat treatment, and project-specific inspection can also be incorporated when dimensional control and downstream processing are critical.
