Hastelloy heat exchangers

Hastelloy heat exchangers are ideal for more challenging process requirements such as high temperatures or working with corrosive substances. This makes them well suited for petrochemical, chemical, and oil and gas industries – as well as many others.

With strong corrosion resistance and the ability to handle more extreme temperatures, Hastelloy makes a reliable choice for many heat exchanger applications.

Sterling TT is a specialist in bespoke heat exchangers. We design and manufacture products from specialist materials, including Hastelloy, zirconium, titanium, tantalum and more. If you’re looking for a high-performing, reliable heat exchanger, get in touch today.

Features of Hastelloy heat exchangers

In an effective application, Hastelloy heat exchangers can provide:

  • Ability to work efficiently in very high-temperature applications
  • Very strong corrosion resistance
  • Low failure rate
  • Reduced downtime
  • Long equipment lifetime, even when working with corrosive materials
  • An effective solution for a wide operating temperature range
  • Ability to handle high pressures, and pressure fluctuations

The choice to use Hastelloy in a heat exchanger must be made with a full understanding of your process. This ensures it’s the best material for your requirements. Talk to an expert at Sterling TT to start your design journey.

About Hastelloy

Hastelloy is a nickel-based, high-grade alloy. It’s well known for its corrosion resistance, as well as its ability to withstand high temperatures and temperature changes without cracking.

It is made from a mixture of nickel, chromium, and molybdenum, with traces of other metals. The precise mixture dictates the type of Hastelloy (listed below). While each kind has its unique properties, all can provide high heat transfer efficiency, the ability to operate in high temperatures, corrosion resistance and, as such, a long lifecycle and low failure rate.

The 10 alloys in the Hastelloy family include:

  • Hastelloy B-3
  • Hastelloy C-2000
  • Hastelloy C-22
  • Hastelloy C-22HS
  • Hastelloy C-276
  • Hastelloy C-4
  • Hastelloy G-30
  • Hastelloy G-35
  • Hastelloy Hybrid-BC1
  • Hastelloy N

Hastelloy C-type variations are the most used in heat exchangers. They are the most versatile and can also be found in many other applications aside from heat exchangers, particularly in fabrication industries.

Applications of Hastelloy heat exchangers

We find Hastelloy heat exchangers in various industries but are most common in industrial applications with a high risk of corrosion. For example, chemical process, petrochemical, oil & gas and pharmaceutical industries, to name a few.

Hastelloy heat exchangers can be designed for processes that involve wet oxygen, sulfuric acid, sulphurous acid, acetic acid, formic acid, hypochlorite, and other reducing or oxidising acids – among others.

Hastelloy can be used to manufacture a range of different heat exchanger types, including industrial condensers, reboilers, shell and tube heat exchangers.

Alternatives to Hastelloy

Depending on the heat exchanger application, Hastelloy might not always be the most cost-effective or efficient choice of material.

Alternative materials might serve better such as titanium, zirconium or tantalum.
