Water, oil, acid and steam working conditions of the media plate heat exchanger plate material selection, you know?

Plate heat exchanger plate as the most important heat transfer link of the plate exchange system, the quality of the metal material directly affects the service life of the equipment. So in the parameters selection design, plate exchange manufacturers will be strictly in accordance with the parameters provided by the user to repeat the design, the flow through the medium will also confirm its physical properties to ensure the selection of the corresponding material to avoid leakage!

For different media and what kind of plate should be selected? Today in the three heart to take you to understand the following.
Water
Common tap water, pure water in general we choose stainless steel 304 material; then if it is well water, river water, closed loop water and other media, we have to consider using 316L, because the composition of these media are more complex, 304 corrosion resistance is not as good as 316L. Then if it is seawater, then we must give priority to pure titanium GR1 material, seawater chloride ion concentration is relatively high, titanium material can meet the requirements. If you consider the cost performance, super stainless steel 254SMO can also be used in 316L above the chloride ion environment.
Acid
Dilute sulphuric acid concentration of less than 10%, the temperature is less than 50 ℃, you can use stainless steel 316L material, if greater than then need to use super stainless steel 904L, 254SMO or Hastelloy C276 and other materials. The same principle applies to phosphoric and hydrochloric acids.
Steam
Steam conditions are more common, generally the South choose to use stainless steel 316L material, because the temperature of steam is generally above 120 ℃. The North will choose 304 material in consideration of the cost of the customer, but over time, the plate heat exchanger plate has the possibility of deformation
Oil
General equipment lubricating oil, hydraulic oil are selected stainless steel 304 material. High-temperature heat transfer oil is considered high-temperature resistance performance, in the three heart recommended the use of 316L stainless steel material.
