Custom Design and Fabrication


Every Shell and Tube Heat Exchanger is Unique

Every application of a shell and tube heat exchanger is unique in one respect or another. While standardized designs have their place, Perry Products designs for our customer’s unique set of circumstances on a job-by-job basis.

Whether you need a 4″ diameter heat exchanger 3′ long or a 100″ diameter heat exchanger 40′ long, Perry Products will custom design a solution to meet your needs.

Design Process

Every design starts with process conditions and development of a thermal design (diameter, number of tubes, tube diameter, etc.) that is both economical to manufacture and optimized for the highest possible thermal and hydraulic efficiency based on the situation. Perry Products will accept and use our customer’s thermal design, optimize our customer’s design and/or develop an optimized design using process conditions provided by our customer. We also check rate designs for our customers.

Our engineers mechanically design per ASME code Section VIII, Division 1, TEMA RCB standards, API, NACE, PIP standards and customer specific requirements.

Whether a single pass heat exchanger with a fixed tubesheet, a multi-pass heat exchanger with a floating head, or replacement components such as channels, shells, u-tube bundles, etc, Perry Products can provide the most economical design to meet your requirements.

Expedited Design and Fabrication Available

Perry Products can custom design, fabricate and ship pipe size heat exchangers in as little as 4-6 weeks using our Rapid Production Process (RPP) program. Even large heat exchanger can be shipped in record time with 24/7 capabilities.


HTRI Thermal Design


Thermal Design and Vibration Analysis Based on Time-Tested Heat Transfer Research Incorporated (HTRI) Heat Exchanger Design Software.

Once process conditions have been identified, the first step in Perry Products’ shell and tube heat exchanger design is to evaluate design alternatives using HTRI software, optimizing the thermal design for the required process conditions.

HTRI heat exchanger design calculations are backed by years of extensive research and data collected on heat transfer equipment.

Using fluid properties, and other design parameters specified by customers and our thermal engineers, fully incremental calculations of localized heat transfer and pressure drop are completed. The resulting optimized heat exchanger design is accompanied by a data sheet and summary calculations such as mean metal temperatures, number of baffles required, number of tubes required, outside diameter of the tubes, the overall tube length, baffle placement, pressure drop, and all other important parameters. HTRI software also performs vibration analysis based on each design’s tube configuration, baffle data, nozzle configuration, flow velocities and fluid properties. Calculations, tables, graphs and drawings provide confirmation of the entire thermal and hydraulic design process.


3D Mechanical Design


Compress, PVElite, RCS and FE Pipe, Perry’s Mechanical Design Software That Complies With ASME Code Requirements.

Mechanical design includes application of thermal design parameters in sophisticated mechanical design programs such as Compress, PVElite, FEPipe and RCS. Mechanical design software is used to optimize the design in terms of material thickness, selection, and overall compliance with ASME, TEMA, API, PIP, NBIC, NACE and other customer specification requirements.

3D Scale Models

Using the results from the mechanical design software, 3D models are generated in Solidworks for verification of nozzle placement, dimensions, support locations, structural mounting requirements and other key design factors. ASME code calculations are generated with the drawing package for customer review and approval. After customer approval, shop drawings are released for fabrication.
