Sondex​ Heat Exchanger Plates

1. Heat transfer plates are one of the key components of plate heat exchangers. These plates are formed with a controlled corrugation pattern through a single constraint forming process, which increases the effective heat transfer surface area. The corrugated design promotes turbulent flow as the fluid passes through the channels, thereby enhancing the heat transfer process. Each plate serves as a dedicated heat transfer surface, with cold and hot fluids flowing on opposite sides of the plate, separated by sealing gaskets. The main types of heat transfer plates in plate heat exchangers include protrusion plates, traversing plates, and herringbone plates. Among these, the herringbone plate design is commonly preferred in the heating industry due to its ability to induce turbulent flow even at low flow velocities (typically ranging from 0.15 to 0.85 m/s) and achieve high heat transfer coefficients on both sides of the plates.

Heat Exchanger Plate Material Choose:

• 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 better 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 chloride ion environments, surpassing the performance of 316 stainless steel.
• 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.
• 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, over time, there is a possibility of deformation in the plate heat exchanger.
• Oil:For general equipment lubricating oil and hydraulic oil applications, stainless steel 304 is suitable. For high-temperature heat transfer oil, considering the requirement for high-temperature resistance, stainless steel 316 is recommended.
