Reglassing

When is reglassing needed?

• The addition of more plugs, patches or sleeves becomes uneconomical, or results in a repair of questionable integrity
• Spalling of the glass due to nascent hydrogen attack
• Galvanic corrosion caused by the use of dissimilar metals in the reactor, like dip pipes, valves and/or repair plugs
• Substantial damage caused from the loss of a repair plug
• Build up of extremely corrosive or erosive products from batch type operations and pilot operations
• Contamination of jacket heating and cooling media, causing accelerated corrosion at the bottom closure ring
• Lack of venting, which can allow corrosion-producing air pockets at the top jacket closure ring
• Damage caused from a component being welded to the substrate during replacement
• Accidental damage to the lining of the vessel
• Mechanical damage, e.g. a workman drops a tool or other object he shouldn't have in his pocket
• Poor workmanship on a repair
• Thermal shock or stress beyond the safe limits of the glass
