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.
