Stainless Steel Bioreactors

At HOLLOWAY AMERICA, we engineer stainless steel bioreactors to exacting specifications because we understand the critical nature of Pharmaceutical and Biotech industries.

In fact, we excel at meeting those standards.

We’re passionate about crafting completely customized processes that meet your most unique or challenging specifications. We also use high-quality finishes that exceed industry norms. Each vessel we craft is inspected and tested to ensure all requirements are met or surpassed. When you size your vessels and design your bioprocessing suites, you can rely on our reputation and dedication to ensure your processes are carried out with utter precision.

We craft ASME vessels from 6" diameter up to 144" diameter and test each and every vessel to meet stainless steel ASME code requirements. We are capable of construction using almost any 300 Series Stainless Steel material as well as most High Nickel Alloys.

Whether your process demands an ASME mixer tank, bioreactor, or any of our other ASME stainless steel pressure vessels, our available surface finish regimen covers a broad range. From Mill plate to Standard Grit finish offerings, all the way to low mechanical 5Ra to 10Ra range, all our surface finishes can be complemented by our in-house H-Electropolish™ service.

When ordering our stainless steel bioreactors or batch reactors, here are just a few things you can expect:

• Vessel sizes from one liter to 30,000 liters 
• ASME-certified welders and BPE certified materials 
• International standards available upon request include PED/CE/CRN/MOM/NR-13/D1 (China)
• In-house finish requirements from 30Ra to 5Ra, with and without H-Electropolish™
• Custom-drilled sprayballs with Riboflavin proof testing and certifications
• Material options from 316L stainless steel, Duplex, AL-6XN®*, HASTELLOY®*, and many other high-alloys
• FAT (Factory Acceptance Testing) room, and complete documentation packages in hard copy and digital copies as standard

HOLLOWAY AMERICA holds both ASME “U” and National Board “R” stamps. Below are a few of the stainless steel ASME codes and standards we meet:

• ASME Section VIII, Division I “U”

• CRN (Canadian Registration Number)
• NR-13
• MOM (Ministry of Manpower)  

All welders at HOLLOWAY AMERICA are certified to ASME Section IX.

To ensure the ASME pressure vessels we engineer perform to perfection and are built to last, we use only excellent stainless materials:

• T–316L (standard)
• T–304L
• T–317L
• C–22
• C-276/HASTELLOY®*
• AL-6XN®*
• Other materials available by request
