The tube sheet is a key component in heat exchange equipment, typically round and flat, with numerous holes evenly distributed for the insertion of heat exchange tubes. It is commonly found in shell and tube heat exchangers, condensers, boilers, and other equipment, facilitating fluid isolation and thermal energy exchange through precise hole design and sealing structures.
Tube Sheet
Is a key component in heat exchange equipment, typically round and flat, with numerous holes evenly distributed for the insertion of heat exchange tubes. It is mainly used to fix and separate the heat exchange tube bundle while ensuring efficient heat transfer between different media (such as liquids and gases) during the heat exchange process. It is commonly found in shell and tube heat exchangers, condensers, boilers, and other equipment, facilitating fluid isolation and thermal energy exchange through precise hole design and sealing structures.
It can be made from materials such as 10#, 20# carbon steel, 16MnR, 12Cr1MoV alloy steel, and ASTM A403, 1Cr18Ni9Ti stainless steel. For product dimensions, typical diameters in the petroleum and chemical industry range from 1,200 to 2,500mm, with typical thicknesses of 60 to 150mm; the applicable standards are TEMA R type and ASME VIII 150-300. In the nuclear power industry, typical diameters range from 2,000 to 4,000mm, with typical thicknesses of 150 to 300mm, and the applicable standard is ASME III. Based on actual needs, sealing surface types such as flat (FF), raised face (RF), and ring joint (RJ) can be used.
As a core component of heat exchange equipment, the tube sheet, with its high precision structure, corrosion resistance, and efficient heat transfer performance, has become an indispensable component in fields such as energy, chemicals, and environmental protection. Its design balances strength and sealing ability, significantly improving equipment efficiency and safety.
