Corrosion-Resistant S4A S21A 0.6mm Sondex Heat Exchanger Plate For Various Fluids

Sondex​ Heat Exchanger Plates

1. Plate heat exchanger plates are the core components of plate heat exchangers, and heat exchange between cold and hot fluids occurs on the plates. The plate and corrugation types of plate heat exchangers should be determined according to the needs of the actual heat exchange working conditions. The products are mainly suitable for replacement of spare parts for international brand plate heat exchangers such as GEA (Kelvion)/ APV/ Sondex/ Tranter/ Hisaka/ API/ Funke/ Vicarb/ Mueller/ SWEP/ Fischer/ AGC/ Thermalwave/ ITT/ LHE/ DHP.

Selection of plate material for plate heat exchangers:

1. Common tap water:For pure water applications, stainless steel 304 is commonly chosen. However, for well water, river water, closed-loop circulating water, and other complex media, stainless steel 316 is preferred due to its superior corrosion resistance compared to 304. In the case of seawater, pure titanium (GR1) is the preferred choice due to the high concentration of chloride ions. Alternatively, for a cost-effective option, super stainless steel 254SMO can be used in environments with higher chloride ion content than 316.
2. Acid:For dilute sulfuric acid with a concentration below 10% and a temperature below 50℃, stainless steel 316 can be used. However, if the concentration is higher, materials such as stainless steel 904L, 254SMO, or Hastelloy alloy C276 are required. The same principle applies to phosphoric acid and hydrochloric acid.
3. Steam:Steam conditions are commonly encountered. In the southern regions, stainless steel 316L is typically chosen since steam temperatures are generally above 120℃. In the northern regions, considering cost factors, some customers may opt for stainless steel 304. However, it should be noted that prolonged use of stainless steel 304 in high-temperature steam applications may result in deformation of the plate heat exchanger.
4. Oil:For general equipment lubricating oil and hydraulic oil applications, stainless steel 304 is suitable. For high-temperature heat transfer oil, where high-temperature resistance is required, stainless steel 316 is recommended.
