Discover ASME Code Requirements for Large Heat Exchangers

When designing and manufacturing industrial heat exchangers, it is important to adhere to the American Society of Mechanical Engineers (ASME) Code. ASME Code sets forth specific requirements for the engineering, design, and construction of industrial heat exchangers and pressure vessels. These requirements help to ensure that heat exchangers are safe and reliable. Here’s what you need to know about how an industrial heat exchanger manufacturer makes ASME-compliant heat exchangers.


ASME is a professional organization that provides guidance and standards for the design and construction of industrial machines and systems. The Code governing the design and construction of industrial heat exchangers is part of the ASME Standard Code for Industrial Mechanical Systems, Section VIII (Pressure Vessels)    

Code defines the requirements necessary to design and fabricate pressure vessels and heat exchangers, including the mechanical calculations needed for shell and head thicknesses, flange calculations, and nozzle reinforcement.  Code also specifies material, welding, and non-destructive testing requirements, among other things.

ASME Code requires that industrial heat exchangers be pressure-tested to ensure safety and leak-free performance. The tests required to meet the ASME code are described in the ASME Section VIII-Div1, UG-99.

Manufacturing an Industrial Heat Exchanger

Rules apply to:

– Materials (ASME II-A, B, C, D)

– Design (ASME VIII Div I & Div II)

– Testing & Inspection (ASME V)

– Welding (ASME IX)

To produce an industrial heat exchanger that meets the requirements of the ASME code, the manufacturer must comply with the Code’s specifications.

The manufacturer must track and inspect the individual materials that make up the overall exchangers, such as rolled plates, formed heads, forgings, and piping. This is a function of the quality control department.

The manufacturer must ensure that the exchangers are manufactured using ASME Code-approved materials as defined in Section II. The materials used in the construction of heat exchangers must meet specific physical and chemical properties, in addition to being produced and tested as defined by ASME.    

Why ASME Standards Matter

When it comes to complex and critical equipment like heat exchangers, having a set of standards to which manufacturers must adhere is essential. ASME Code ensures that industrial heat exchangers are designed and manufactured to standards that are common and universally understood within the industry.       

These standards are critical not just for directing the manufacturing quality of heat exchangers, but for the safety of the public at large. By adhering to the ASME code, buyers and manufacturers are sure that their heat exchangers are safe and effective.
