We offer thermal and mechanical designs, based on the parameters you provide. All of our fab work, machining, tube-sheet drilling, PWHT, RT, hydro tests, and painting is performed by our staff at our shop in Bellevue, Ohio USA. Also, we offer PMI testing for when the chemistry of your high alloy tubes and tube-sheets is critical.
We fabricate all of our custom shell and tube heat exchangers to the latest TEMA standards. Unless directed otherwise by our customer we build to Class “R” which is the most heavy duty of the three TEMA classes. TEMA is the Tubular Exchanger Manufactures Association. They are known worldwide for setting the standards of design. At times, they release new editions of their standards. So, we always design using the newest edition they provide.
We have a wide range of experience in working to the ASME code. So, stamping your HX to Sect. VIII, Div. 1, 2, or 3 is no problem. Since we have have a good grasp of the ASME code, we can ensure that your units are not only well designed and durable, but safe for you, your property, and your employees.
Corrosion and erosion result over time from the fluids and gases that move through the exchangers at very high speeds. As a result, the need for repairs will happen. In addition to being a manufacturer of heat exchangers, we are able to repair and re-tube your unit. Then, we can re-certify it with the NBBI, since we hold the National Board “R” Repair stamp. Please contact us today to discuss your repair needs.
They transfer heat between two different mediums. It could be two liquids, two gases, or one gas and one liquid that are transferring heat. Many industries make use of them, especially the processing and refining industries. In many cases custom shell and tube heat exchangers are manufactured to efficiently make use of the heat created by an industrial process that would otherwise be lost. This boosts the efficiency and lessens the waste of the plant because the heat can be recycled! In most cases, a hot fluid flows through the tubes past a cool fluid in the shell (and vice-versa) without touching. Often, the end goal is to create steam, which can then be harnessed as energy.
Didon’s Mechanical is a family of companies, which includes Didion Vessel, Didion Autoclave, and Didion Separator. All are owned and operated by the Didion family in Belleuve, Ohio USA.
