Product Description

Corrosion-Resistant Titanium & Titanium-palladium Alloy Heat Exchanger Plate for Heat Exchanger

Heat Exchanger Plates

1. Plate heat exchanger plates are specially designed components used in plate heat exchangers to isolate media and facilitate heat exchange. They are essential parts of plate heat exchangers.
2. The plates of plate heat exchangers are made by pressing metal sheets with corrugations, sealing grooves, and corner holes. They serve as crucial heat transfer elements. The corrugations not only enhance heat transfer but also increase the rigidity of the thin plates, thereby improving the pressure resistance of the plate heat exchanger. Additionally, the turbulent flow induced by the corrugations helps reduce the formation of deposits or fouling, providing a certain degree of "self-cleaning" effect.

Products are mainly suitable for /ACCESSEN/GEA (Kelvion)/ APV/ Sondex/ Tranter/ Hisaka/ API/ Funke/ Vicarb/ Mueller/ SWEP/ Fischer/ AGC/ Thermalwave/ ITT/ LHE/ DHP, etc.

Applacations

Plate heat exchanger plate thickness configuration

• AISI 304 is usually 0.4 or 0.5 mm thickness
• AISI 316 is always 0.5 and 0.6 mm
• 254 SMO (high alloy) typically 0.6 mm
• Titanium plates are always 0.5 and 0.6 mm
• Some have thicker plates (for high pressure applications)
• Some PHEs have 0.4 mm (low pressure operation)
• Hastelloy C-276 (nickel alloy) typically 0.6 mm

Production Process:

• Raw material preparation: High-quality stainless steel plates are selected as raw materials due to their excellent corrosion resistance and thermal conductivity. The plate thickness is determined based on product specifications and design requirements.
• Cutting and leveling: The stainless steel plates are accurately cut using machine tools to meet the design requirements. After cutting, leveling treatment is performed to ensure a smooth and even surface.
• Stamping: The flattened plates undergo stamping using a hydraulic press to create specific herringbone patterns. The resulting plates have a high turbulence coefficient, promoting efficient heat transfer. Precise control is maintained during the stamping process to prevent plate deformation or damage.
• Surface treatment: The plates undergo surface treatment such as polishing, sandblasting, or coating to enhance corrosion resistance and heat transfer performance. The choice of treatment method depends on specific requirements.
• Assembly and inspection: The plates are assembled according to the design requirements, forming a detachable plate heat exchanger with rubber gasket seals or a fully welded plate heat exchanger through argon arc welding. Tight fitting and absence of gaps are ensured during assembly. A rigorous performance pressure test is conducted after assembly, and a factory report is issued to verify compliance with quality standards
