ITT Titanium Plates for Corrosive Heat Exchanger Duties
ITT titanium plates are independently manufactured replacement components for identified gasketed plate heat exchangers. Titanium is often considered for selected seawater and chloride-bearing services, but it is not universally compatible with every chemical. The plate pattern and titanium material specification must both be confirmed before production.
Plate Compatibility
The replacement must reproduce the physical features required by the existing exchanger. A matching outside shape alone does not confirm correct fit, sealing or fluid routing.
- Overall dimensions and hanging features
- Port diameter and center distances
- Corrugation pattern and pressing direction
- Gasket groove and attachment points
- Open and closed ports for each pack position
Titanium Suitability
Material review should include both heat exchanger circuits and every chemical used during operation or cleaning. Confirm the existing plate material instead of identifying it from color or surface appearance.
- Complete process and service-fluid composition
- Chloride content and other dissolved species
- Normal and maximum temperatures and pressures
- Cleaning chemicals, concentration and exposure time
- Previous corrosion or failure evidence
When Should Titanium Plates Be Evaluated?
Titanium may offer advantages in specific environments where stainless steel has insufficient corrosion resistance. Final selection still depends on the complete chemistry, temperature and cleaning regime.
Seawater Service
Titanium is commonly evaluated for seawater cooling and related marine duties. Actual water chemistry, temperature, fouling and cleaning conditions should be supplied.
Chloride-Bearing Water
Elevated chloride exposure can make stainless steel selection more difficult. Report concentration, temperature and any local concentration changes within the system.
Repeated Stainless Failure
Pitting or rapid corrosion in existing stainless plates justifies a full failure review before another alloy is selected.
Process Upgrades
Changed raw materials, higher temperatures or new cleaning chemicals can alter material requirements even when the exchanger model remains unchanged.
Information Required Before Ordering ITT Titanium Plates
Accurate quotations depend on separating equipment compatibility, plate-pack arrangement and process-material requirements.
| Confirmation item | Buyer information required | Reason for confirmation |
|---|---|---|
| Equipment identity | Complete model, nameplate photograph and serial details where available | Establishes the initial reference for plate identification. |
| Plate geometry | Overall dimensions, port measurements, hanging details and corrugation pattern | Confirms that the plate can fit and align within the frame. |
| Gasket groove | Groove profile, sealing path and gasket attachment method | Ensures the matching gasket can seat and seal correctly. |
| Plate position | Flow, turning, start, end or another defined position | Determines port closures, plate orientation and gasket arrangement. |
| Titanium specification | Installed material marking, previous specification or approved material requirement | Avoids supplying an unconfirmed titanium grade or condition. |
| Process conditions | Both fluids, concentrations, temperatures, pressures and operating cycles | Supports material evaluation for the actual duty. |
| Cleaning procedure | Cleaning agent, concentration, temperature, duration and frequency | Cleaning exposure must be included in the compatibility review. |
| Order scope | Quantity by plate position, matching gaskets and destination country | Supports accurate quotation, checking and packing. |
Confirm the Plate Pattern When Records Are Incomplete
Older heat exchangers may have missing nameplates, unclear codes or undocumented plate-pack changes. Measurements and photographs are required when the model reference cannot establish the exact configuration.
Record the Frame
Photograph the complete exchanger and nameplate, including every model, serial and service marking that remains readable.
Prepare a Reference Plate
Clean one representative plate sufficiently to expose markings, port areas, gasket grooves and corrugations.
Measure Critical Features
Record overall length and width, port diameter, port-center distances and the upper and lower hanging details.
Photograph Both Faces
Take full, perpendicular photographs of the front and reverse sides, plus close views of markings and ports.
Identify Pack Position
State where the plate is installed and which ports are open or closed. Record different plate groups separately.
Verify the Material
Provide material markings, previous order records or available alloy verification instead of relying on appearance.
Review Why the Existing Plates Failed
Replacing damaged plates without identifying the failure mechanism can lead to repeated shutdowns. Inspect where the damage began and whether it affects isolated plates or the complete pack.
Corrosion Damage
Record pitting, crevice attack, edge corrosion and damage near ports or gasket grooves. Include fluid and cleaning changes that occurred before leakage began.
Mechanical Damage
Check for bent edges, distorted hanging points, dented heat-transfer areas and damage caused during dismantling, cleaning or reassembly.
Operating Damage
3>Report pressure shocks, thermal cycling, vibration or abnormal compression where cracking or deformation cannot be explained by corrosion alone.
Individual Plate Replacement
Individual replacement may be appropriate when damage is isolated, the remaining pack is serviceable and the exact plate position, pattern, material and gasket arrangement can be confirmed.
Complete Plate-Pack Review
Inspect the complete pack when leakage, thinning, corrosion or deformation is widespread. Record the compressed dimension and plate sequence before removing the plates.
Preserve Plate Position and Orientation During Maintenance
The plate pack may contain multiple corrugation directions and port configurations. Maintaining the sequence is necessary for correct flow distribution and sealing after reassembly.
Before Dismantling
- Record the compressed plate-pack dimension
- Mark a diagonal line across the complete pack
- Photograph the first and last plate arrangements
- Separate plates with different port closures
- Record representative gasket orientations
During Incoming Inspection
- Compare dimensions with the approved reference
- Verify corrugation direction and port arrangement
- Inspect hanging points and gasket grooves
- Confirm quantities for every plate position
- Protect titanium surfaces and plate edges from damage
Coordinate Titanium Plates with the Correct Gasket
The gasket must match the plate groove, sealing path and attachment method. Elastomer selection remains a separate process decision and should be based on the fluids, temperatures and cleaning chemicals.
Profile and Groove Fit
The gasket must sit correctly in the titanium plate groove without stretching, twisting or obstructing the intended sealing areas.
Attachment Method
Confirm whether the installed plate uses a glued, clip-on, snap-in or another gasket attachment configuration.
Elastomer Compatibility
EPDM, NBR, FKM and other available materials have different chemical limits. Provide complete operating data before selecting the gasket.
Replacement Plates for Maintenance and Distribution Orders
We operate precision stamping, rubber molding, CNC machining and final-inspection workshops within our 3,500 m² facility. Our quality processes are managed under an ISO 9001-certified system. We can coordinate titanium plates with matching gaskets, private labeling and custom packaging after confirming the technical specification.
Specification Review
Plate markings, dimensions, photographs, pack positions and process conditions are reviewed before the production specification is finalized.
Position-Based Checking
Different plate patterns and port configurations should be listed by position so quantities can be checked before packing.
OEM Requirements
Private-label and packaging requirements can be discussed when identification details, packing method and order quantities are supplied.
ITT Titanium Plate FAQ
What information is needed to quote ITT titanium plates?
Provide the heat exchanger model, nameplate photograph, plate markings, dimensions, port measurements, photographs of both faces, required plate positions and quantity. Include the titanium specification or complete process and cleaning conditions for material review.
Are titanium plates suitable for every chloride-bearing fluid?
No. Chloride content alone does not establish compatibility. Supply the complete fluid composition, concentration, temperature, pressure, contaminants and cleaning conditions before confirming titanium for the application.
Can stainless steel plates be upgraded to titanium?
A material change may be considered after reviewing the cause of stainless steel failure and the complete operating environment. The replacement plate must still match the existing geometry, ports, gasket groove and plate-pack arrangement.
Can individual titanium plates be replaced?
Individual plates may be replaced when the remaining pack is serviceable and the exact plate position is known. Confirm the corrugation orientation, port configuration, material and gasket arrangement for each replacement plate.
Is the ITT equipment model enough to identify the correct titanium plate?
The model is a useful starting point but may not confirm every configuration. Plate markings, dimensions, corrugation, port closures, gasket groove and installed position should also be checked before production.
Can matching gaskets be supplied with ITT titanium plates?
Matching gaskets can be reviewed with the plate order. Provide the groove configuration, attachment method, fluids, temperatures and cleaning conditions so the gasket fit and elastomer material can be confirmed.
