Baffles and spacers are critical components in heat exchanger cores that direct fluid flow and maintain structural integrity for optimal thermal efficiency.
| Parameter | Typical range | Notes & selection driver |
|---|---|---|
| Tolerance | ±0.5 mm on critical dimensions | |
| Baffle Cut | 15-45% of shell diameter | |
| Baffle Spacing | 0.2-1.0 x shell diameter | |
| Surface Finish | Ra ≤ 3.2 μm for fouling resistance | |
| Tube Support Spacing | ≤ 1.5 m for vibration control |
Ranges are indicative industry figures for RFQ preparation, not a supplier commitment. Confirm every value and standard with the legal manufacturer before ordering.

Manufacturer profiles associated with Baffles / Spacers.
Explore company information and manufacturing capabilities, then discuss the scope of your project with a relevant supplier.
Baffles redirect shell-side fluid flow across tube bundles to increase turbulence, enhance heat transfer coefficients by 30-60%, and prevent dead zones that reduce thermal efficiency.
Spacers maintain tube alignment, dampen flow-induced vibrations that cause fatigue cracking, and prevent tube sagging under thermal expansion, reducing failure risks by up to 70%.
