Specifications that decide fit
- Material of construction: glass-lined for corrosive and high-purity processes, stainless steel or alloys such as Hastelloy for others.
- Design pressure and temperature of both the vessel and the jacket or half-pipe coil.
- Volume, nozzle layout, agitator type and drive, and the type of shaft seal (single or double mechanical seal).
Condition checks
- Glass-lined reactors: a spark (holiday) test and visual inspection show whether the lining is intact; repairs with tantalum plugs are common but should be recorded.
- Stainless and alloy reactors: check welds and surfaces for pitting or stress-corrosion cracking.
- Agitator, gearbox and seal condition, and whether the jacket has been pressure-tested.
Documents to ask for
Ask for the nameplate data, pressure vessel certification (for example PED or ASME), material certificates, the last inspection or pressure test report and, for glass-lined vessels, the most recent spark test result.
Questions buyers ask
How can I tell if a used glass-lined reactor is still good?
A high-voltage spark test detects pinholes and damage in the glass lining. Combined with a visual inspection and the repair history, it is the main indicator of remaining life.
Can I use a used reactor at a higher pressure than on its nameplate?
No. The nameplate design pressure and temperature are the limits for vessel and jacket; rerating requires a formal engineering assessment.
Do used reactors need new certification?
That depends on local pressure-equipment rules. Original certification and inspection records usually make recertification straightforward.
