How can you perform spark test in glass line reacter?

To perform a spark test in a glass-lined reactor, first ensure the reactor is clean and dry. Then, use a high-voltage spark tester to apply a voltage between the glass lining and the metal shell; this checks for insulation integrity. Monitor for any signs of arcing or breakdown, which would indicate defects in the glass lining. If the test passes without any issues, the reactor is deemed safe for operation.
