Titanium Heat Exchanger Baffle Plate Custom Drilled Hole For Chloride Shell‑Tube Heat Exchanger
Опубликовано Engineering Team, Shaanxi Qianyi Tuoda Technology Co., Ltd от 2026-10-25
1. Product Identity
Based in Shaanxi Baoji China, titanium heat exchanger baffle plate is custom‑machined component specially used inside shell‑and‑tube heat exchangers. It is processed from Gr2 / Gr12 Titanium Plate via CNC high‑precision hole drilling, deburring and flatness correction. Different from ordinary titanium sheet, core value lies in tube‑hole positional accuracy, hole‑edge burr‑free quality and flatness tolerance. Baffle plates guide cross‑flow medium, adjust flow velocity and support titanium heat‑exchange tubes. Widely deployed in brine, salt‑lake and chemical chloride‑rich heat‑exchange system. We deliver semi‑finished blank or fully‑drilled finished baffle plates according to customer heat‑exchanger drawing.

4. Mechanical & Corrosion Performance
-
Gr2 Tensile ≥345 MPa; Yield ≥275 MPa; Elongation ≥20%
-
Gr12 provides improved resistance to reducing acid medium besides chloride corrosion resistance.
-
Corrosion‑erosion performance: Resist high‑speed brine cross‑flow scouring; hole‑edge without micro‑notches to avoid local flow‑accelerated corrosion.
-
Processing note: Drilling residual burr cannot be reserved; burrs will trigger vortex erosion and early‑stage hole‑edge failure under fluid scouring condition.
5. Full Size Range
-
Base plate thickness: Determined by heat‑exchanger design load
-
Outer outline: Circular / segmental / double‑segment baffle shape as per drawing
-
Tube hole: Custom hole diameter, hole pitch, hole position tolerance, quantity of holes
-
Custom service: Notch cut‑out for bypass channel, lifting lug reserved, flatness correction post‑machining.
6. Surface Treatment Options
-
Pickling: Remove machining oxidation, standard for heat‑exchanger internal components.
-
Mechanical deburring: Remove inner hole sharp edges, mandatory process for baffle plate.
-
Passivation: Enhance anti‑erosion property for harsh brine circulating environment.
7. Material Comparison: Titanium Baffle Plate vs 316L Baffle Plate
|
Item
|
Titanium Baffle Plate
|
316L Stainless Steel Baffle Plate
|
|
Anti‑erosion in brine cross‑flow
|
Resist chloride flow‑accelerated corrosion
|
Easy hole‑edge pitting under high‑chloride scouring
|
|
Weight
|
Lightweight, reduce overall equipment dead‑load
|
Heavy weight, increase shell‑side load
|
|
Service life in salt‑lake media
|
Long service cycle
|
Prone to local hole‑edge failure
|
|
Cost feature
|
Higher initial investment, low replacement frequency
|
Low purchase cost, frequent maintenance risk
|
Titanium baffle plate avoids hole‑edge pitting and erosion failure which commonly occurs for stainless steel under brine cross‑flow scouring in shell‑tube heat exchangers.
8. Strict Quality Control & Test Items
-
Raw Titanium Plate incoming inspection including chemical and flatness check.
-
CNC machining program verification before batch drilling production.
-
Tube‑hole position & aperture dimension inspection using coordinate measuring instrument.
-
100% visual inspection for hole‑edge burr, sharp notch and machining scratch.
-
Flatness re‑check after flattening procedure.
-
Issued documents: EN10204 3.1 MTC, dimension inspection report, batch traceability record.
9. Export Packaging & Shipment
-
Inner packing: Anti‑rust film + hard separator board between each baffle plate, prevent hole‑edge collision damage.
-
Outer packing: Fumigated wooden case with supporting frame, avoid plate bending during sea transit.
-
Marking: Mark drawing number, grade and batch number on each finished piece.
-
Trade terms: FOB, CIF, DDP; sea freight for heat‑exchanger project batches.
