ITT Stainless Steel Plates for Identified Heat Exchanger Configurations
ITT stainless steel plates are independently manufactured replacement components for servicing compatible gasketed plate heat exchangers. Before production, the plate geometry, port layout, corrugation, gasket groove and installed position must be identified. The required stainless steel alloy should be confirmed separately from the process fluid and cleaning conditions.
Dimensional Compatibility
A plate with a similar external outline may still have a different pressing pattern, port configuration or gasket channel. Identification should cover every feature affecting suspension, plate contact, fluid routing and sealing.
- Overall plate length and width
- Port diameter and port-center distances
- Corrugation pattern and pressing orientation
- Gasket groove and attachment features
- Plate markings and installed pack position
Material Compatibility
The term "stainless steel" does not define one universal material. Confirm the installed alloy where possible and supply complete process data when choosing material for a new duty or investigating premature corrosion.
- Fluid names and chemical concentrations
- Chloride level and other relevant contaminants
- Normal and maximum operating temperatures
- Cleaning chemicals and cleaning temperature
- Previous pitting, cracking or edge-corrosion evidence
Details to Confirm Before Ordering Stainless Steel Plates
Plate identification and material selection are separate decisions. Both must be correct for the replacement plate to fit the exchanger and remain suitable for the operating environment.
| Specification item | Information required | Purchasing significance |
|---|---|---|
| Heat exchanger identity | Complete model, nameplate photograph and serial information where available | Provides the starting reference for plate-pattern identification. |
| Plate geometry | Dimensions, port measurements, corrugation and hanging details | Confirms mechanical fit on the carrying and guide bars. |
| Plate position | Flow, turning, start, end or another identified pack position | Determines port closures, orientation and gasket arrangement. |
| Stainless steel alloy | Installed material marking, previous specification or material selection data | Prevents an unspecified stainless grade from being substituted without review. |
| Operating conditions | Fluids, concentrations, pressures, temperatures and operating cycles | Supports evaluation of the plate material under actual service conditions. |
| Cleaning conditions | Cleaning agent, concentration, temperature, duration and frequency | Cleaning exposure can influence corrosion and service life. |
| Order scope | Quantity by plate position, gasket requirement and destination country | Allows an accurate quotation and coordinated packing plan. |
When Stainless Steel Requires Additional Evaluation
Material suitability depends on the combined effects of fluid chemistry, temperature, contamination, cleaning and operating history. A familiar application name does not replace detailed process data.
Chloride Exposure
Report chloride concentration and temperature for both circuits. Local concentration changes and deposits should also be considered when previous plates show localized attack.
Cleaning Chemistry
Identify every cleaning product used, including concentration, temperature and contact time. Incorrect cleaning conditions can damage a plate that performs acceptably during normal operation.
Process Changes
Review changes in raw materials, water source, chemical dosing, temperature or production cycle before replacing failed plates with the same material.
Failure Location
Record whether corrosion occurs near ports, beneath the gasket, at contact points, along plate edges or across the heat-transfer area.
How to Identify a Legacy ITT Stainless Steel Plate
Older installed equipment may have incomplete records or difficult-to-read markings. A structured set of measurements and photographs helps distinguish plates that share a similar external shape.
Photograph the Nameplate
Capture the complete equipment nameplate and any model, serial or service information still visible on the frame.
Clean One Reference Plate
Expose stamped markings, the gasket groove, port areas and full corrugation without damaging the plate surface.
Measure the Plate
Record the overall length and width, port diameter, port-center distances and hanging or guide features.
Record Both Faces
Photograph the complete front and reverse sides perpendicular to the plate so the pressing direction can be compared.
Identify Its Position
State where the plate sits in the pack and document which ports are open or closed at that position.
Confirm the Material
Provide any material marking, previous order record or alloy test result available instead of specifying only "stainless steel."
Replace Individual Plates or Refurbish the Plate Pack?
The appropriate order quantity depends on the failure pattern, the condition of the remaining plates and whether every replacement position can be identified reliably.
Individual Replacement
Suitable for isolated mechanical damage or localized failure when the remaining plates have been inspected and the exact plate position, pattern and port arrangement are known.
Multiple-Plate Replacement
Consider replacing a defined group when several plates share the same damage mechanism or when different plate positions must be supplied together to preserve the flow arrangement.
Complete Pack Review
Inspect the full pack when corrosion, thinning, deformation or repeated leakage is widespread. The plate sequence and compressed dimension should be recorded before dismantling.
Before Removing the Plates
- Record the compressed plate-pack dimension
- Draw a diagonal sequence line across the plate pack
- Photograph the first and last plate arrangements
- Separate plates with different patterns or closed ports
- Record gasket orientation on representative plates
Before Installing New Plates
- Compare dimensions with the approved reference plate
- Check port closures and corrugation orientation
- Inspect gasket grooves and hanging features
- Verify quantities for each specified plate position
- Keep plate surfaces and edges protected from damage
Match the Gasket to the Plate Groove and Process Fluid
A compatible plate requires a gasket with the correct profile, sealing path and attachment method. Gasket material must also be reviewed against the process fluids, operating temperatures and cleaning conditions rather than selected solely from the plate material.
Groove Fit
The gasket profile must seat correctly inside the stainless steel plate groove without stretching, twisting or obstructing the intended sealing path.
Attachment Method
Confirm whether the existing design uses glued, clip-on, snap-in or another attachment arrangement before ordering replacement gaskets.
Elastomer Selection
State the fluids, concentrations, temperatures and cleaning chemicals so EPDM, NBR, FKM or another available option can be reviewed for compatibility.
Replacement Plate Supply for Maintenance and Distribution
WTSML operates precision stamping, rubber molding, CNC machining and final-inspection workshops within its 3,500 m² facility. Quality processes are managed under an ISO 9001-certified system. Plate orders can be coordinated with matching gaskets, private labeling and custom packaging after the product specification and order scope are confirmed.
Specification Review
Model information, plate markings, measurements, photographs and process conditions are reviewed before the replacement specification is finalized.
Position-Based Packing
Where an order contains different plate positions or patterns, quantities should be listed separately for checking and packing.
OEM Requirements
Provide private-label, identification and packaging instructions during quotation so the applicable requirements can be confirmed for the order.
ITT Stainless Steel Plate FAQ
What information is required to quote ITT stainless steel plates?
Provide the heat exchanger model, nameplate photograph, plate markings, dimensions, port measurements, photographs of both plate faces, required plate positions and quantity. Include the stainless steel alloy or complete process conditions for material confirmation.
Is specifying stainless steel sufficient for production?
No. Stainless steel includes different alloys with different corrosion behavior. The installed grade should be confirmed where possible. If it is unknown, provide fluid chemistry, temperature, pressure, cleaning conditions and corrosion history for review.
Can the equipment model alone confirm the correct plate?
The model is an important reference but may not confirm the complete configuration. Plate dimensions, corrugation, ports, gasket groove, material and installed position should also be checked before production.
Can corroded stainless steel plates be replaced with the same material?
They can be replaced with the same material only after the cause of failure has been considered. Changes in chloride level, temperature, cleaning chemistry, deposits or process conditions may make a different alloy worth evaluating.
Can individual ITT heat exchanger plates be replaced?
Individual plates may be replaced when the remaining pack is serviceable and the exact plate position can be identified. Confirm the port configuration, corrugation orientation, material and gasket arrangement for each replacement plate.
Can matching gaskets be supplied with stainless steel plates?
Matching gaskets can be evaluated with the plate order. Provide the gasket attachment method, process fluids, temperatures and cleaning conditions so the groove fit and elastomer material can be confirmed.
