ASME Pressure Vessels

Perfectly crafted vessels that perform under pressure.

HOLLOWAY crafts ASME pressure vessels to code, as with the ASME mixer tank pictured here. ASME pressure vessels by HOLLOWAY can come with open-top design.

ASME Pressure Vessels. Built to Code. Built to Perform.

All ASME Pressure Vessels that leave our facility proudly bear our name. And, antiquated as it may seem, we were brought up with the simple belief that if you’re going to put your name on something, it better be right. Period. It’s this mentality that pushes HOLLOWAY AMERICA to achieve the highest level of quality and design for any product that bears our nameplate. We’ve been hand-crafting ASME Pressure Vessels long enough to understand that our equipment is our very best calling card. 

HOLLOWAY builds ASME Pressure Vessels from 6" diameter up to 144" diameter and test each and every vessel to meet the stainless steel ASME code requirements with flying colors. 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 or an ASME Bioreactor or any other ASME pressure vessel, 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 can be complemented by our in-house H-Electropolish™ service.

Limitless Capabilities for ASME Pressure Vessels

No matter which industry you serve—Chemical, Diary, Pharma, Biotech, Munitions and more—and no matter what your sizing requirements—Lab Scale or Oversized Fermentation units—we have the right team to assemble whatever style and design you have in mind. 

An ASME Mixer Tank. Vertical or Horizontal Units. Quick-Access Open-Top Designs. Square Bodied Units. Even Tulip Design Vessels are in our playbook. There isn’t much we haven’t seen in our decades of building and fabricating some of the finest Pressure Vessel equipment in the industry.
