Large Diameter Machining

To provide efficient production of our quality pressure vessels, Didion's Mechanical uses in-house machining processes with cutting, lathe, mill and drill capabilities. Didion's can machine large diameter flanges up to 108" OD.

We hold the American Society of Mechanical Engineers (ASME) U, U2, U3, PP, & S stamps, and have the capabilities and resources to design and manufacture custom flanges to your exacting specifications

The Didion’s Mechanical Advantage

As a family business, we give special attention to the quality of each custom fabrication that leaves our shop, and we respond quickly to your questions and concerns. We also have the drive what seems at times to be impossible completion dates.

Our in-house engineering, drafting, fabrication, machining, radiography, and heat treatment facilities help us to keep tight control over the quality and delivery of each custom fabrication, which is often lost with the use of subcontractors. With little dependence on third party vendors, we are able to honor your deadlines.

The Didion’s Mechanical team is standing by to assist you with your machining requirements. For more information, please send us an e-mail at or call us at (419)483-2226 .
