Custom ASME Heat Exchanger Fabrication: Engineered for Performance and Reliability

A heat exchanger may be one part of a larger system, but its performance can have a big impact on the entire operation. The right design can improve reliability, withstand harsh conditions, and help prevent costly downtime. At Alloy Engineering, we combine engineering expertise and advanced fabrication capabilities to create custom ASME heat exchangers built for the challenges our customers face. 

Custom Heat Exchanger Design Backed by Engineering Expertise 

Every application comes with its own challenges, which is why we take a customized approach to heat exchanger design. Our team designs a variety of ASME heat exchanger systems, including shell-and-tube, air-cooled, and finned-tube heat exchangers, recuperators, and economizers. 

We use industry-leading tools, including HTRI thermal design software and CodeCalc mechanical design software, to create solutions that meet both performance goals and ASME Code requirements. As an ASME-certified manufacturer, we fabricate equipment with S, U, and R stamps, giving customers confidence that their equipment is designed and built to rigorous quality standards. 

Built for Challenging Industrial Environments 

Industrial heat exchangers often have to operate in some of the toughest environments, from extreme temperatures to exposure to corrosive materials. We understand these challenges and have the expertise to design and fabricate equipment to withstand them.

Our custom ASME heat exchangers can include:

• Shell diameters up to 80 inches, with in-house machining capabilities up to 110 inches turning 

• Temperature ratings up to 1600°F for high-temperature applications 

• Carbon steel, stainless steel, high nickel alloys, and reactive metals 

• High-temperature gas-to-gas exchangers, bayonet heat exchangers, and double tube sheet designs 

• Nickel brazed finned tubing, refractory-lined components, and explosion-clad construction 

• Clean-room fabrication and welding for specialized applications 

• SolidWorks 3D fabrication drawings for accurate production and documentation 

Whether you need a new heat exchanger designed from the ground up or a specialized solution for an existing process, our team works closely with customers to develop equipment that fits their needs. 

Serving Industries That Depend on Reliable Heat Transfer 

Our ASME heat exchangers support critical operations across industries such as chemical processing, power generation, and other high-temperature manufacturing applications. These industries rely on equipment that performs consistently, even in the most challenging environments. 

Beyond new fabrication, Alloy Engineering also provides replacement and repair services to help extend the life of existing equipment. We can manufacture replacement bundles, channels, shells, and tube sheets to restore performance and help reduce unexpected downtime.
