Plate and Shell Heat Exchanger
A plate & shell heat exchanger combines the high heat transfer efficiency and compact structure of plate heat exchanger technology with the high temperature and pressure resistance of traditional shell & tube heat exchangers. The heat transfer equipment consists mainly of a welded plate pack and an external shell. Different fluids flow through the plate side and shell side separately. The two flow paths deliver efficient heat transfer in a compact structure. Thus, it suitable for applications that require both high thermal performance and reliable operation under demanding conditions.
- Laser Welding Technology: Laser welding provides higher weld quality and faster processing speed compared with traditional welding methods such as plasma welding and TIG welding. The process reduces thermal deformation and heat-affected areas to approximately 10–20% of conventional welding methods. With high power density reaching 10⁵–10⁷ W/cm² and a depth-to-width ratio up to 10:1, laser welding creates strong weld joints without additional filler materials. The result is improved pressure resistance, longer service life, and stable operation.
- Full Helium Leak Testing: Each unit undergoes helium leak testing with continuous suction probe inspection. The testing method enables highly sensitive leak detection to verify sealing performance and support safe, reliable operation.
- Corrosion Resistance: Pickling and passivation treatment forms a dense chromium oxide layer on stainless steel surfaces that enhances corrosion resistance and extending equipment durability under corrosive operating conditions.
- Flexible Configuration: The modular design allows multiple units to be connected in series to increase heat transfer length or configured with parallel channels for different flow requirements. This flexibility enables the equipment to adapt to various operating conditions.
- High Thermal Stress Resistance: The optimized structure provides balanced stress distribution and effectively withstands thermal vibration and impact caused by rapid temperature changes.
