Forged ASTM A266 Gr.2 Carbon Steel Tubesheet for Pressure Vessel and Heat Exchanger Application
ASTM A266 is a standard specification for carbon steel forgings for pressure vessel components. It covers four grades of carbon steel forgings, namely Grade 1, Grade 2, Grade 3, and Grade 4. Each grade has different chemical composition and mechanical properties, but all are suitable for use in pressure vessel applications. The selection of a specific grade of ASTM A266 will depend on the specific application requirements and design considerations. ASTM A266 Gr.2 is a low to intermediate carbon steel grade that is commonly used for pressure vessel components such as tubesheets, flanges, and fittings. It has good mechanical properties, including high strength and toughness, and is suitable for use in a variety of pressure vessel applications, which typically be used in a heat exchanger or other type of shell and tube pressure vessel. The use of ASTM A266 Gr.2 for the tubesheet ensures that it is strong enough to withstand the pressure and temperature conditions of the application.

It's important to note that the selection of materials for a pressure vessel should be made based on a number of factors, including the specific application requirements, design considerations, and applicable codes and standards. A qualified engineer or materials specialist should be consulted to ensure that the appropriate materials are selected for the application.
Applications
Tube plate is widely used in tubular heat exchangers, boilers, pressure vessels, steam turbines, large central air conditioners, condensers, evaporators and other products. The metal material makes it not only rigid, but also has great heat conduction performance. The precision of tube plate processing, especially the tolerance of hole spacing and diameter, perpendicularity, and finish greatly affect the assembly and performance of the equipment listed above.
