ASME SA240 316L Stainless Steel Baffle Plate for Shell and Tube Heat Exchanger
ASME SA240 316L stainless steel baffle is a fabricated heat exchanger component manufactured from 316L stainless steel plate.
It is mainly used in shell and tube heat exchangers to support tube bundles and guide shell-side fluid across the tubes. The baffle geometry, thickness, tube hole arrangement, and cutout are normally designed according to the heat exchanger drawing and thermal design requirements.
The baffle can be supplied as a standard segmental baffle or other customized configurations according to equipment design.
Material Standard: ASME SA240
Material Grade: 316L
Material Type: Austenitic Stainless Steel
Product: Heat Exchanger Baffle Plate
Fabrication: Cutting, Drilling and Machining
ASME SA240 covers chromium and chromium-nickel stainless steel plate, sheet, and strip for pressure vessel and general applications.
For a fabricated heat exchanger baffle, the material can be supplied from SA240 316L stainless steel plate, while the final baffle dimensions and configuration are manufactured according to the equipment drawing.
316L is a low-carbon austenitic stainless steel grade containing chromium, nickel, and molybdenum.
The low carbon designation is reflected by the "L" in 316L.
Typical alloying elements include:
Chemical composition and mechanical properties shall comply with the applicable ASME SA240 requirements.
Segmental baffles are commonly used in shell and tube heat exchangers.
The baffle contains:
The cutout orientation and baffle spacing can be customized according to the heat exchanger design.
The baffle provides mechanical support for the tube bundle and helps control tube vibration within the shell.
The baffle forces shell-side fluid to pass across the tube bundle according to the designed flow path.
This arrangement is used to establish the required shell-side flow pattern and heat transfer area utilization.
316L stainless steel plate is supplied according to ASME SA240 requirements.
The baffle outline and segmental cutout are produced according to the engineering drawing.
Tube holes are machined according to:
The baffle edges and tube holes can be deburred and finished to the specified requirements.
