Didion Separator

Didion Vessel, Autoclave, and Separator are all branches of Didion’s Mechanical, which 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. Now, many know us by the names of our branches which more accurately describe our focus of work.
