Allegheny Bradford Heat Exchangers

Allegheny Bradford (ABC) custom designs the most efficient, cost effective heat exchangers for your thermal transfer requirements. From the documentation of raw materials in compliance with ASME BPE codes, to the precision CNC machining of tubesheets and bonnets, to final finishing, testing and documentation, ABC exchangers are manufactured to deliver superior performance and trouble-free operation, even in the most demanding ultra-pure processing environments. Specially designed computer software combines fluid dynamics, thermophysical properties, thermodynamics and actual empirical data to ensure your shell and tube heat exchanger design is perfect for your application.

The ABC skilled craftsmen operate state-of-the-art machinery and equipment to custom fabricate the highest quality, sanitary shell and tube heat exchangers available.

Standard manufacturing features included with every heat exchanger:

• 100% success rate for FDA Validation Protocol for over forty (40) years
• 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 2005 compliant U-tube and straight-tube designs
• Stringent QA/QC procedures
• Unsurpassed document control department to ensure receipt of all necessary validation documentation

Standard benefits performed by the ABC expert heat exchanger design team include:

• All multi-pass exchangers, straight-tube or U-tube, include accurate counter-current and co-current flow analysis
• Straight-tube or U-tube designs
• 100% vibrational and acoustic resonance analysis
• 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
