Fixed Tubesheet Configuration
Maximum Seal Integrity with Rigid Double-Welded Tubesheets
Discuss with Engineers
PAL Certified Quality
Technical Overview
Our Fixed Tubesheet heat exchangers feature tubesheets welded directly to both ends of the shell. This rigid construction ensures maximum mechanical seal integrity and prevents any fluid bypass, making it the ideal choice for clean, non-fouling fluids and chemical processes.
Engineering Specifications
| TEMA Configuration | TEMA L/M/N Types (e.g., AEL, BEM) |
| Tubesheets | Two, welded directly to the shell |
| Tube Cleaning | Straight tubes allow mechanical cleaning inside |
| Thermal Expansion Joint | Optional shell bellows expansion joints |
| Leak Prevention | Zero leakage between shell and tube streams |
Key Engineering Features
Maximum Seal Integrity
Since the tubesheets are welded to the shell, there are no internal gaskets or packing joints, eliminating any path for external leaks.
Inner-Tube Cleanability
The straight-tube design allows brushes or mechanical cleaning rods to pass fully through the tubes for easy scaling removal.
Compact Shell Clearance
Minimal clearance between the shell and the outermost tubes optimizes flow distribution and maximizes the active heat transfer area.
