Custom made by the manufacturer! Hastelloy C276 plate and shell heat exchanger

Recently a domestic customer ordered a plate and shell heat exchanger from our factory, which in itself is not special, what is special is the customer's Operating conditions, the customer's operating condition is to heat 1% sulfuric acid with saturated water vapor. Sulfuric acid is corrosive, and dilute sulfuric acid is more corrosive. Therefore, we designed a Hastelloy C276 plate and shell heat exchanger for the customer.

In fact, this is not the first time we have used special materials in the manufacturing of heat exchangers, from export to domestic sales, in the face of complex and corrosive media conditions, we have accumulated a wealth of experience in the use of special materials such as Hastelloy, titanium, titanium-palladium alloys, 254SMO stainless steel, nickel and other special materials.

One of the most important problems customers face before coming to us is that the internal media of the plate and shell heat exchanger cascade liquid, which is initially expected to be media Corrosive, and the use of heat transfer plate and the use of improper selection of material from the piping to the plate. Stainless steel 316L has a certain degree of corrosion resistance, but not at high temperatures, or in contact with more corrosive media.

Hastelloy C276 is a nickel-based alloy, which is one of the high corrosion resistance of the current metal material, and also has strong corrosion resistance. Thermal stability. Often used in the aerospace industry, chemical field, etc. In harsh corrosive environments, such as petrochemical, flue gas desulfurization, pulp and paper industry, environmental protection and other industrial fields have quite a wide range of Applications.

Faced with this situation, you have to choose the Hastelloy C276 plate and shell heat exchanger. Because of the high temperature conditions, as well as the corrosive media conditions dictate that a plate heat exchanger should not be selected.

Hastelloy C276 plate heat exchanger is designed to prevent the emergence of corrosion and the occurrence of cascading liquid phenomenon, in the media through all places with Hastelloy C276, will be the receiver flange, loose flange over, and the receiver, the heat exchanger core all replaced with C276, so as to delay corrosion, improve product life, and stability.
