Glass Lined Equipment Service Highlights
InKorr has recently completed on-site service on a glass-lined decomposition reactor for one of our clients in the chemical process industry. Glass-lined equipment are commonly utilised in chemical and pharmaceutical plants as reactors, agitated mixers, storage tanks, and columns to handle highly corrosive fluids. The integrity of the glass lining in these vessels should be inspected and tested regularly as any undetected cracks, deformation, or pinholes can lead to heavy corrosion to the outer steel shell.


InKorr’s service technicians were mobilised on-site to inspect and test two units – one reactor in-situ and a spare unit in the storage yard. The glass lining for each unit was visually examined and any imperfections were noted down and reported.
Following the visual inspection, spark testing was performed on the vessel body and components including the agitator, manhole cover, nozzles, mechanical seal. etc. Spark testing is an effective method of identifying cracks and pinholes in the glass lining that often cannot be seen by the naked eye. The external metallic shell is charged and a current is detected wherever there is any damage on the surface of the glass lining.
During inspection and spark testing, a crack was found on a previously repaired section in the vessel. The old PTFE gasket and Tantalum plate were removed and the glass surface was carefully cleaned and prepared for a new repair. The new gasket and plate were moulded to securely fit against the concave surface of the glass and to completely cover the existing damaged area.

Following the on-site service, InKorr also supplied an identical spare of the mechanical seal flange. Through InKorr’s partnership with 3V Tech Glasscoat in Italy, we are able to offer re-glassing services and supply of replacements / spare parts for glass-lined components that cannot be repaired.
