Are the plates of SS304, 316L, Hastelloy, and titanium unclear? Large heat exchanger manufacturers tell you the answer

Many of Ripter’s customers include heat transfer oil, milk heat exchange, marine aquaculture, rich and poor liquid exchange... Some of them will directly buy the corresponding model based on the heat exchanger used before, and some

It is to let the designer help in the selection.

But no matter what it is, our customer service staff will carefully ask about the working conditions and give suggestions. Sure enough, many problems were found.

But before that, we must first give you a popular science about what kind of working conditions should correspond to what kind of material.

The most widely used material. At that time, stainless steel 304 and 316L were the main ones, which can easily deal with the food industry. However, if your food processing contains chloride ions, such as processing certain marine products or coastal city operations, use 316LIt is necessary to replace 304.

Other special materials like Hastelloy are mostly used in industrial scenes.

For example, 254 smo is an advanced version of 316. If there are salt water conditions that 316 cannot handle, 254 smo must be used.

Titanium can also be used in such conditions, but it is more resistant to temperature. Seawater below 135°C, salt solutions of various concentrations below 165°C, and organic acids below the boiling point are where titanium plays its greatest role.

Chloride ions have almost no effect on Hastelloy 276, and its home field is sulfuric acid of various concentrations.

But like 304, there are nickel plates that are not resistant to chloride ions. Nickel plates are mainly used in high-concentration, high-temperature caustic solutions.

So you know how important the parameters are when selecting a model. With the support of the physical parameters of the medium, the selected heat exchanger will be more accurate.

From material to thickness, etc., this will ensure that this heat exchanger is truly suitable for you.
