APV Titanium Plates Matched to the Existing Plate Pack
APV titanium plates are independently manufactured replacement components for identified gasketed plate heat exchanger configurations. Titanium is commonly evaluated for seawater, chloride-bearing water, and compatible process duties, while the plate geometry, grade, thickness, orientation, and gasket arrangement must match the existing pack.
Plate Compatibility
- Overall length, width, and edge profile
- Port diameter and center spacing
- Corrugation pattern and plate orientation
- Gasket groove and retaining features
- Hanging points, titanium grade, and thickness
Process Compatibility
- Fluids and concentrations on both circuits
- Chloride level and water composition
- Normal and cleaning temperatures
- Pressure conditions and flow velocity
- Cleaning chemicals and possible contamination
Information Needed for Titanium Selection
| Selection factor | Information to provide | Why it matters |
|---|---|---|
| Titanium grade | Existing material record, plate marking, purchasing specification, or analysis where necessary | Confirms the required titanium specification instead of assuming all grades are interchangeable. |
| Water chemistry | Water source, salinity, chlorides, treatment chemicals, contaminants, and suspended solids | Supports assessment of corrosion, fouling, deposits, and service suitability. |
| Process fluid | Chemical names, concentrations, additives, pH where available, and possible contamination | Titanium compatibility varies with chemical composition and operating conditions. |
| Temperature | Normal, maximum, cleaning, start-up, and shutdown temperatures | Temperature can change corrosion behavior and chemical compatibility. |
| Cleaning | Chemical name, concentration, temperature, contact time, and frequency | Cleaning exposure may be more demanding than normal operation. |
| Failure history | Locations and photographs of erosion, deposits, cracking, deformation, or perforation | Existing damage helps determine whether material, operation, or maintenance requires review. |
When Titanium May Be Evaluated Instead of Stainless Steel
Seawater Circuits
Titanium is commonly considered for seawater cooling and compatible marine-water services after confirming the complete operating conditions.
Chloride-Bearing Water
Where chloride exposure increases localized-corrosion risk for the selected stainless grade, titanium may require evaluation.
Corrosion-Related Upgrade
Repeated stainless steel pitting may justify a material review, but the corrosion mechanism should be investigated before changing alloys.
Titanium Plates Must Reproduce the Existing APV Pattern
Corrugation Geometry
The pressed pattern forms the flow channels and plate contact points. Pattern, depth, and orientation must match adjacent plates.
Port Arrangement
Open and closed ports control fluid routing. Channel, turning, transition, start, and end plates may use different configurations.
Gasket Groove
The field seal, port rings, diagonals, vents, clips, and tabs must accept the confirmed compatible gasket profile.
How to Confirm an APV Titanium Plate
Identify the Exchanger
Provide the APV model, nameplate photograph, serial information, design data, and maintenance records.
Record Plate Markings
Photograph all stamped, embossed, etched, or printed identification on the front and rear surfaces.
Measure the Plate
Include overall dimensions, port diameter, port centers, thickness record, edges, and hanging-point details.
Document the Pattern
Send full-face photographs showing corrugations, orientation, port openings, gasket groove, and plate handing.
Confirm the Material
Provide the recorded titanium grade, fluid chemistry, chloride conditions, cleaners, and corrosion history.
Define the Order
Confirm plate types, quantities, gasket requirements, spare allowance, labeling, and destination.
Inspect Failed Plates Before Reordering
Plate Damage to Record
- Perforation or localized material loss
- Cracks at corrugations or contact points
- Erosion near ports or high-velocity areas
- Deposits, scale, or unusual discoloration
- Distorted gasket grooves, edges, or hanging points
- Damage caused during cleaning or handling
Operating Data to Compare
- Which fluid contacted the damaged surface
- Fluid composition and recent chemical changes
- Normal and peak operating temperatures
- Flow changes and suspended solids
- Cleaning chemicals and cleaning frequency
- Previous plate and gasket service history
Verify the Titanium Plates Before Installation
Compare Geometry
Compare dimensions, ports, corrugations, gasket groove, hanging features, orientation, and thickness records.
Confirm Material
Check the specified titanium grade and maintain material identification for mixed-material or multi-exchanger orders.
Match the Gaskets
Confirm gasket profile, elastomer, retention method, port sealing, and orientation before rebuilding the pack.

- Confirmed private-label and export-packaging requirements
APV Titanium Plate FAQ
What applications are APV titanium plates commonly evaluated for?
Titanium is commonly considered for seawater, chloride-bearing water, and selected compatible process duties. Final selection requires the full fluid chemistry, temperature, pressure, cleaning media, and titanium specification.
Is titanium suitable for every chloride-containing fluid?
No material should be approved from chloride content alone. Provide the complete fluid composition, concentration, temperature, pH where available, contaminants, cleaners, and exposure conditions.
Can stainless steel plates be replaced with titanium plates?
A material change requires review of fluid chemistry, gasket compatibility, plate geometry, thickness, pack configuration, possible material interaction, and the cause of the original corrosion.
Can one APV titanium plate be replaced individually?
Individual replacement may be possible when the exact plate type, pattern, orientation, port arrangement, titanium specification, thickness, gasket configuration, and pack position are confirmed.
Can titanium plates be supplied with compatible gaskets?
Yes. Provide the required gasket material, retention method, process conditions, plate quantities, and whether the gaskets should be packed separately or fitted to the confirmed plates.
Are these original APV titanium plates?
No. They are independently manufactured replacement plates intended for confirmed compatible APV gasketed plate heat exchanger configurations. The APV name is used only to identify compatibility requirements.
Confirm the Titanium Grade and APV Plate Geometry
Send the exchanger model, plate markings, front and rear photos, dimensions, titanium specification, thickness, fluids, cleaning conditions, gasket requirement, quantity, and destination.
