Reglassing is a complex process that provides efficient, cost-effective repair to old, damaged or worn glass-lined vessels and their accessories, such as agitators, baffles and covers.
Once a vessel or ancillary part is reglassed it is equivalent in quality to a new item. The reglassing procedure involves the following steps:
- Removal of the old glass lining from a vessel or part by grit-blasting
- Repair of the steel substrate by welding (e.g. stud holes from plugs and corrosion-damaged areas are ground out and patch welded, severely corroded sections may be trepanned and a new section welded in)
- Addition or removal of nozzles or other changes (such as replacement of jacket closure rings or addition of diaphragms)
- Application and firing of numerous coats of glass
- Testing before and after glassing
- Application of external protective coatings
