Semi-Welded Plate Heat Exchanger_Efficient Corrosion-Resistant Heat Transfer Equipment_Industrial Heat Exchange Custom Solutions
The semi-welded plate heat exchanger is a high-efficiency heat transfer equipment that integrates the dual advantages of laser welding and sealing gaskets. Specifically designed for high-temperature, high-pressure, corrosive working conditions and mixed medium heat exchange needs, it combines the stability of fully welded equipment and the maintenance flexibility of detachable equipment. It is an ideal alternative to traditional shell-and-tube heat exchangers in industries such as chemical, refrigeration, petrochemical, and metallurgy, and is core-adapted to the upgrading needs of industrial heat exchange for high efficiency, energy saving, and safety.
Core Advantages: Technology Empowers Multi-Dimensional Breakthroughs
Efficient Heat Transfer & Energy Consumption Optimization: Adopting corrugated plate design and countercurrent flow channel structure, combined with high-speed turbulent flow effect between plates, the heat transfer coefficient is much higher than that of traditional shell-and-tube heat exchangers, ensuring more sufficient heat exchange; the filling volume of special media is small, which greatly reduces operating energy consumption and medium loss, helping enterprises achieve energy saving, cost reduction and environmental protection compliance.
High Pressure & Corrosion Resistance, Safety & Reliability: Plate pairs adopt laser welding technology, with small welding deformation, low residual stress and excellent sealing performance, which can withstand a maximum design pressure of 50bar and a maximum operating temperature of 150℃; plate materials include 304, 316L, titanium, titanium-palladium, Hastelloy C276 and other corrosion-resistant materials, and gaskets are made of NBR, EPDM, VITON/FKM and other temperature and corrosion-resistant materials, effectively preventing medium leakage and cross-contamination, and suitable for corrosive fluid processing scenarios.
Compact Structure & Easy Installation: Compared with shell-and-tube heat exchangers, it has smaller volume and lighter weight, with an area of only 30%-50% of traditional equipment. The modular design is suitable for installation scenarios with limited space; it is fixed by tightening bolts, the installation process is simple, and subsequent expansion or modification is more flexible.
Easy Maintenance & Long Service Life: Welded flow channels ensure the stability of key working conditions, and gasket flow channels support detachable cleaning and component replacement without overall disassembly, which greatly shortens the shutdown maintenance time; the mesh contacts of the plates support each other, enhancing rigidity and excellent frost resistance. It can be restored to use after freezing, and is not prone to cracks and other damages, with a significantly longer service life than ordinary equipment.
