This product is suitable for tube sheet applications in heat exchangers, condensers, and other process equipment. Unlike a general disc, a tube sheet forging must accommodate later hole drilling patterns, sealing surfaces, and more demanding dimensional control. It is usually supplied as a forged or rough-machined blank prepared for tube hole machining and final fabrication according to project requirements. Tube sheet projects usually require more than a simple round blank, because later drilling layout, flatness, thickness control, and machining stability will directly affect exchanger assembly and sealing performance. For this reason, customers often prefer a forged blank when the section is heavy, the material requirement is strict, or the final equipment service demands a more reliable base structure. Depending on the manufacturing route, the product can be prepared as a forging blank, rough-machined blank, or semi-finished plate ready for drilling, facing, and final tube-sheet machining.
