Fixed-Tubesheet Exchanger with Shell Expansion Joint
High metal-temperature-difference duty where a fixed tubesheet needs axial relief
| Industry | Process heating (undisclosed) |
|---|---|
| Equipment | Shell & tube with metallic expansion bellow |
| Application | High metal-temperature-difference duty where a fixed tubesheet needs axial relief |
| Challenge | Accommodate shell growth without converting the design to a floating head. |
| OHM solution | Mid-shell expansion joint detailed on the fabrication drawing and welded into the shell course. |
| Manufacturing scope | Shell, bellows course, channel flanges, nozzles. |
| Location | Manufactured in Vadodara, Gujarat. End-user site not published. |
| Testing / quality | Weld inspection of the bellows attachment and pressure testing as specified on that order. |
| Design approach | Keep a fixed tubesheet and relieve shell growth with a metallic expansion joint instead of converting the rear head to a floating type Ohm does not list as a manufactured SKU. |
| Manufacturing lessons | Expansion-joint attachment welds are hold points. Photograph and map them before coating hides the joint. |
| Delivery / export | Shop completion in Vadodara. Installation site not published. |
| Result | Configuration visible on the completed shell — expansion joint in situ. |
