ASME SA516 Gr.70N Stationary Tubesheet For Boilers With Great Weldability
Tubesheets are extensively utilized in a variety of industrial applications, including shell and tube heat exchangers, boilers, pressure vessels, steam turbines, and large central air conditioning systems.
Customized high-precision tubesheets, on the other hand, are mainly used in chemical containers for operations such as shell and tube heat exchangers, boilers, pressure vessels, condensers, central air conditioning systems, evaporators, and water desalination. These tubesheets serve the important function of providing support for fixed shell and tube units.
Due to their metallic composition, the tubesheets possess outstanding rigidity and heat conduction performance.
A SA516 Gr.70N stationary tubesheet is a component used in heat exchangers and pressure vessels. It is made from SA516 Grade 70N carbon steel, which is a high-strength material that is commonly used in the construction of pressure vessels due to its excellent toughness and weldability.
The tubesheet is designed to hold the heat exchanger tubes in place and provide a seal between the tubes and the shell of the heat exchanger. The stationary tubesheet is typically welded or bolted to the shell of the heat exchanger and serves as a fixed point for the tubes to be attached to.
SA516 Grade 70 usual request normalized if thickness above 40mm, if not, Gangsteel usual delivery in hot rolled or control rolled station. A516 Gr.70+N or A516gr70N mean that steel grade must be normalized in any thickness.
SA 516 GR.70 vs 70N
SA 516 GR.70 and 70N are pressure vessel grades that can be differentiated based on certain features.
GR.70N is a metal in a normalized condition. The GR.70 is not subjected to the normalizing process.
The normalized 70N grade possesses superior ductility and toughness over the A516 70 material.
Where is the stationary tubesheet located in the floating head heat exchanger?
The tubesheet at the rear header end of the shell is of slightly smaller diameter than the shell, allowing the bundle to be pulled through the shell. The use of a floating head means that thermal expansion can be allowed for and the tube bundle can be removed for cleaning.
