Post Weld Heat Treating

Didion's Mechanical has Heat Treating capabilities. Using computer-controlled units, we have the ability to heat treat a variety of vessels sizes with our gas fired furnace. Our system offers a 16 million BTU rating, and can accommodate a part up to 8 ft wide by 11 ft high by 40 ft long. We also make use of electric pads at times if more economical. If you have a requirement too large to fit in our furnace, we have the ability to wrap your vessel with insulation and use our gas burners to provide the controlled heat to the inside for your post weld heat treating.

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 pressure parts to your exacting specifications.

The Didion Mechanical Advantages

As a family business, we give special attention to the quality of each custom design, fabrication, and/or service that leaves our shop, and we respond quickly to your questions and concerns. We also have the drive to meet 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 engineering, fabrication, and/or heat treatment requirements. For more information, please send us an e-mail at or call us at (419)483-2226 .
