The origins of forged tubesheets can be traced back to the high-pressure boilers and steam systems of the Industrial Revolution. In early industrial production, boilers and piping systems had to withstand high-temperature and high-pressure media; standard cast or welded plates struggled to ensure the necessary reliability and service life. Because forging technology significantly enhances the density of a metal's internal microstructure and its mechanical strength, it was increasingly adopted for the manufacture of boiler tubesheets and pressure vessels, establishing them as indispensable components in high-pressure systems.
With advancements in steel smelting and forging techniques, the materials used for forged tubesheets have evolved from carbon steel to alloy steel, stainless steel, and highly corrosion-resistant alloys, resulting in significant improvements in strength, toughness, and corrosion resistance. Concurrently, forging processes have progressed from manual open-die forging to closed-die forging, hydraulic forging, and precision hot forging. These advancements have greatly enhanced dimensional accuracy and structural complexity, enabling tubesheets to meet the rigorous demands of modern industrial environments characterized by high pressure, high temperature, and severe corrosion.
Driven by progress in machining, heat treatment, and inspection technologies, the production of forged tubesheets has become increasingly standardized and systematized. Today, forged tubesheets are widely utilized in sectors such as petrochemicals, chemicals, power generation, metallurgy, and the nuclear industry. Their design, manufacturing, and quality control meet high standards of reliability and safety, making them irreplaceable core components in pressure equipment and heat exchange systems.
