High Pressure Resistance Laser Welded Pillow Plate No Stress Cracking

As a critical heat exchanger component, our pillow plates feature unique manufacturing using advanced laser welding technology. The process involves precise splicing and fixture alignment followed by laser welding, then expansion via air or hydraulic methods to meet specific process requirements.

Our enhanced pillow plates are integrated into wide channel plate heat exchangers for saltwater wastewater incineration systems. These systems handle flue gas containing high concentrations of inorganic salt dust, which can corrode metal materials. Our design effectively controls dust accumulation through optimized flue gas side spacing and plate height parameters.

• High Dust & Temperature Adaptability: Withstands 479℃ inlet temperature, dropping to 348℃ outlet. S30408 material provides high-temperature oxidation resistance. Wide channel design prevents high-concentration dust deposition and reduces blockage risk.
• Salt Corrosion Resistance & Low Resistance Design: S30408 stainless steel withstands chloride ion corrosion from salt-containing flue gas. Minimal 400 Pa hot side resistance ensures smooth flue gas flow.
• Large-Flow Flue Gas Treatment Capacity: Handles 31,000 Nm³/h flue gas flow with optimized plate height and flow channel width for stable high-dust operation.
