                     Glass Lined Reactor 
Failure: Causes & 
Prevention Tips
Glass-lined reactors provide excellent chemical resistance but are 
prone to costly failures. Understanding causes and prevention is key 
to avoiding downtime and ensuring safety.
Material Degradation: The Silent Killer
Chemical Attack Thermal Stress Manufacturing Defects
Aggressive compounds erode the Repeated temperature shifts Weak spots in the lining accelerate 
glass surface over time. generate tiny cracks that worsen. degradation under stress.
Mechanical Stress Threats
Agitator Contact Uneven Torque
Blade striking vessel wall Inadequate flange torque 
causes damage and failure leads to uneven pressure 
risks. and stress.
Poor Cleaning Practices
Residues and improper inspection weaken structural integrity.
Operational Techniques 
Impacting Reactor Life
Temperature Control Pressure Management
Follow manufacturer Regularly de-pressurize 
guidelines for heating and reactors to avoid mechanical 
cooling rates. stress.
Chemical Handling
Observe compatibility and batch changeover protocols carefully.
Temperature Control Best Practices
Avoid Thermal Shocks
Uniform Heating
Never apply cold water directly to hot 
Limit Rate of Change
Ensure temperature changes are glass surfaces.
Increase or decrease temperature by consistent throughout the vessel.

Routine Inspection and 
Maintenance
Visual Inspection
Detect cracks and wear early to prevent extensive 
damage.
Pressure Testing
Verify vessel integrity periodically under controlled 
conditions.
Preventive Repairs
Address minor defects before they escalate into failures.
