The Didion Family

A hard-working family from rural Ohio.

The People Behind the Name

Didion Vessel, Autoclave, and Separator are a family of pressure products manufactured by Didion Vessel, LLC. This LLC is owned and operated by our family in Bellevue, Ohio. Throughout the years, our company has evolved to focus on areas of our expertise that bring the most benefit to our customers and our company.

Don and Jill Didion began the company in 1977 to provide for their growing family, which amounted to five boys. In time, a local soybean processing plant contracted Don as a plumber, and they asked him do do some welding. So, with his widely known “can-do attitude”, he said yes, and that was our start in welding and millwright work. In 1989 we obtained our ASME stamps, and that began our history in code welding. For many years, we also traveled to a wide array of states and overseas for mechanical and millwright work. In recent years, though, our work has focused almost entirely on in-house weldments. Our company was formerly known as Didion’s Mechanical. Now, we go by the name Didion Vessel, which more accurately describes our focus of work.
