The Allegheny Bradford Corporation offices will be closed the week of December 26-December 30, 2022.

They will re-open at 8 a.m. on Monday, January 2, 2023.

After 16 years as the Regional Manager for the mid-west and western United States, Dori Carlson has been named Customer Support Manager for Allegheny Bradford Corporation.

In her new role, Dori will be pivotal in providing superior after-sale support for our customers. She will oversee sale of maintenance parts, general customer inquiries, complaints, troubleshooting, and warranty claims. She will also work closely with Allegheny Bradford’s leadership to help prevent commonly reported issues.

Craig Lynn has assumed duties for Dori’s region and will work closely with Dori to ensure a smooth transition.

What is needed for a heat exchanger to meet the challenges of ultra-high purity applications?

A lot, actually. Engineers have continually fine-tuned heat exchangers over the past several decades to better serve the bioprocessing industry as specified by BPE codes, CGMP regulations, and other standards. Here are 16 basic elements of sanitary heat exchanger design and manufacture:

  1. Shell-and-tube design – Eliminates drainage impediments found in plate-and-frame designs.
  2. Double tubesheets – Greatly decreases the possibility of cross-contamination between shell and tube media.
  3. HydroSwage® sealing of tubes into tubesheets – Prevents excessive tube-wall thinning and spiral stress created by mechanical tube rolling.
  4. Tube-end seal welds – Prevent accumulation of foreign materials in crevices between the tubes and tubesheet.
  5. 2° overall slope toward outlet; no low points or impediments – Provides enhanced drainability.
  6. Fully radiused pass pockets – Allow pass-pocket drainability despite the two-degree slope of the heat exchanger.
  7. Drain channels between pass pockets – Allow upper pass-pockets to drain to the heat-exchanger drain point.
  8. Leak detection slots – FDA-required visual indicator of a breach in a tube-to-tubesheet seal.
  9. 316L stainless steel or higher alloy (AL6XN, Hastelloy®, etc.) – Provides corrosion resistance.
  10. <20 micro-inch Ra product-contact-surface finish – Reduces potential for biofilm buildup.
  11. Electro-polishing – Provides a deeper passive (corrosion-resistant) layer than simple passivation.
  12. Welds polished flush and blended – Reduces areas of potential contaminant buildup.
  13. Seamless tubing – Eliminates potential for inclusions in welded-tube welds.
  14. Special tube-bending dies – Prevent surface disruption of U-tube interiors.
  15. Material not sourced from China, India, Eastern Europe, etc. – Ensures quality steel.
  16. No processing of carbon steel in the same shop as stainless steel – Prevents risk of embedding carbon steel into stainless steel during manufacturing operations, which can create a nucleus for corrosion.

On Friday, July 31st, Allegheny Bradford Corporation closed the sale of its Top Line division to Steel & O’Brien Manufacturing of Arcade, New York. Dan McCune, President and CEO of Allegheny Bradford states, “This is a win/win opportunity for both businesses, allowing Steel & O’Brien to expand its presence in the flow control technologies industry while Allegheny Bradford focuses all its energy and resources on the opportunities developing in the Bio-Pharmaceutical industry.” He adds, “Allegheny Bradford is uniquely positioned to take advantage of the developing US policy of on-shoring America’s medical supply chain.”

Over the next couple of months, the Top Line operations will be integrated into the Steel & O’Brien operations, which will create much needed manufacturing floor space for Allegheny Bradford. This sale, along with the changing business environment and the Allegheny Bradford’s ongoing process improvement programs, gives the Corporation the ability to excel in coming years.

Allegheny Bradford Corporation is a fabricator of sanitary, code stamped pressure vessels and systems worldwide.

First, I just want to say that our hearts go out to everyone impacted by this global pandemic. We extend our heartfelt wishes to anyone who is sick for their full recovery. As much as this pandemic tries to bring morale down, we are inspired every day by selfless healthcare workers and first responders.

Gov. Tom Wolf closed all non-life-sustaining businesses in Pennsylvania due to COVID-19.  We are exempt and we will continue to ship high-quality equipment, components, and provide services in support of our customer’s efforts to supply the nation with life-sustaining food and medicine.

Our Safe Workplace Plan

We want to maintain a safe workplace and adopt practices to protect the health of our employees, customers, visitors, and others.  We have asked all of our employees to cooperate in taking steps to reduce the transmission of communicable diseases in the workplace.

> Employees are encouraged to follow CDC and WHO guidelines like staying home when they are sick, washing their hands frequently, and using sanitizers in high touch areas.
> We are deep cleaning the buildings every Friday evening as employees go home.  We support natural disinfecting by keeping the buildings closed from Friday evening until Monday morning.

> We are taking preventative actions like workplace social distancing through the limiting of third party facility access, limiting inter-facility employee contact, and many employees are working from home.
> Employees are encouraged to use telephone and video conferencing instead of face-to-face meetings as much as possible.

Service and Support

While this is an ever-evolving situation, currently we anticipate no interruptions to our customer service, support, and shipments as part of the critical infrastructure industry.  As the situation changes, we will keep you informed.  Thank you for trusting us with your business.  We will work together in these challenging circumstances to best serve your customers.
