ASME SA516 GR.70N Stationary Tubesheet for Heat Exchanger Accessories Application

A stationary tubesheet is an essential component of a heat exchanger that separates two fluid streams from each other. It is a piece of metal construction that has holes drilled through it to allow heat exchange tubes to pass through. The tubesheet is usually stationary or fixed, meaning it cannot move or rotate relative to the heat exchanger shell.

The main characteristic of a stationary tubesheet is that it is typically welded or clamped in place to provide a secure and leak-proof connection between the tubes and the shell. This design helps to prevent any undesired mixing or contamination of the fluid streams. Stationary tubesheets are commonly used in applications where the thermal, chemical, and mechanical properties of the fluids are known and stable, and no significant variations in temperature or pressure are likely to occur.

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.
