Heavy Tube Sheet Forging provides a superior engineered solution for industrial applications where dimensional stability, material homogeneity, and minimized downstream risk are paramount. By utilizing a forged circular blank instead of plate-based alternatives, these components ensure a refined grain structure and enhanced structural integrity, specifically designed to support rigorous drilling, facing, and boring operations without compromising the forged properties.
Specially engineered for larger or thicker heat exchanger services, our heavy tube sheets are designed to withstand demanding service conditions and high-pressure environments. We focus on strict thickness consistency and stable machining behavior across the entire face, providing customers with sufficient stock for precise pattern machining and ensuring long-term reliability in heavy process equipment.

Forged tube sheets offer superior material homogeneity and a refined grain structure, which significantly reduces the risk of internal defects and provides much higher dimensional stability during heavy machining compared to rolled plates.
Common materials include Carbon Steel (A105), Stainless Steel (A182 F304/F316), Alloy Steels (F11, F22, F91, F92), and Duplex grades, depending on the specific corrosion and temperature requirements of the project.
Yes, we provide various supply conditions including rough-machined and semi-finished parts. This includes facing the OD/ID and establishing drilling datums to help customers reduce their internal machining cycle time.
We offer a comprehensive suite of NDT options including Ultrasonic Testing (UT), Magnetic Particle (MT), Penetrant Testing (PT), Positive Material Identification (PMI), and hardness testing to ensure total quality compliance.
Standard documentation includes EN 10204 3.1 certificates, detailed heat-treatment records, dimensional reports, NDT inspection reports, and marking lists, all compiled into a project-specific dossier.
We work directly from your technical drawings and project specifications to arrange the exact OD, thickness, and machining allowances required, ensuring the final product integrates perfectly into your equipment assembly.
