Just a few of the standard benefits performed by our expert heat exchanger design team include:
- Straight-tube or U-tube designs
- 100% vibrational and acoustic resonance analysis
- All multi-pass exchangers, straight-tube or U-tube, include accurate counter-current and co-current flow analysis
- The U-bend area of U-tube exchangers is not included in the heat transfer calculations or effective area
- Precise expansion and contraction calculations are performed on all straight-tube exchangers to determine expansion joint necessity. (Expansion joints are not needed for U-tube designs)
- Reynolds Numbers are reported with each design to report the efficiency of the design
- Carefully calculated baffle-spacing, baffle-number, baffle-cut and baffle inlet/outlet locations
- Precise tubeside and shellside pressure drop calculations are reported with every design (Based on your allowable pressure drop)
- Precise tubeside and shellside velocity calculations are reported with every design (Utilizing industry accepted minimum values)
- TEMA recommended fouling factors used in every design
- Excess surface area is added to every design
- Ensures exchanger will operate as efficiently tomorrow as it does today
- In the rare event of a ruptured tube, ABC can use a sanitary plug to seal-off the tube
Our highly skilled craftsmen operate state-of-the-art machinery and equipment to custom fabricate the highest quality, sanitary shell and tube heat exchangers available. Just some of our standard manufacturing features included with every heat exchanger:
- Custom designed, state-of-the-art hydraulic tube expansion – no work hardening, scoring, thinning or scarring of the product contact surfaces
- Custom designed, state-of-the-art orbital tube welders for tube-to-tubesheet seal welds
- Proprietary tube-bending apparatus for U-tube designs ensures product contact surface finish adherence in the U-bend area
- All heat exchangers with surface finishes of 0.6-µm to 0.3-µm include electronics-grade seamless tubing
- Sanitary welded tubing is available for surface finishes of greater than 0.75-µm
- 100% ASME BPE 2009 compliant U-tube and straight-tube designs
- Stringent QA/QC procedures
- Unsurpassed document control department to ensure receipt of all necessary validation documentation
- 100% success rate for FDA Validation Protocol for over forty (40) years

Please click here for ABC heat exchanger advantages in Spanish Our state-of-the-art fabrication technology uses high-pressure hydraulic expansion to seal the tube-to-tube sheet joints. This reduces the risk of roller expansion damage, as well as work-hardening effects and excessive thinning of the tubing. In addition, our proprietary integrated double tubesheet virtually eliminates tube-to-tubesheet joint stress. The result is consistent performance, reduced maintenance and extended equipment life. Prior to shipment, every heat exchanger undergoes rigorous testing and comprehensive documentation and turn-over packages.
These procedures that may include:
• Hydrostatic pressure testing
• Dye penetration examination
• X-ray analysis
• Saline testing
• Computer-verified performance
• Profilometer readings of surface finish to ensure mechanical and electropolished surface finishes
to less than 10 microinches Ra
• Fiber optic, borescopic tube inspection and videotaping of product contact surfaces
• ASME Code Stamping with National Board Registration
