High-temperature working conditions put forward strict requirements on the stability, corrosion resistance and structural strength of Plate Heat Exchanger Replacement Plate. Unqualified plate materials are prone to deformation, accelerated corrosion and thermal fatigue damage under long-term high-temperature operation, which will reduce heat exchange efficiency and cause equipment failure. Selecting reliable materials is the core of ensuring the stable operation of high-temperature heat exchange equipment.
For conventional high-temperature water and HVAC systems below 120°C, SS304 and SS316L stainless steel replacement plates are the most cost-effective and stable options, with good high-temperature oxidation resistance. For working temperatures between 120°C and 180°C, 254SMO super austenitic stainless steel is preferred. It maintains stable mechanical properties and corrosion resistance in high-temperature and medium-chloride environments. For ultra-high temperature and strong corrosive chemical working conditions, Hastelloy C-276 and pure titanium plates are reliable choices, which can resist high-temperature stress corrosion and avoid plate perforation.
As a professional manufacturer, we match exclusive replacement plate materials according to actual temperature parameters and working media. All customized plates are tested for high-temperature durability to ensure long-term stable operation of customer equipment.
