Introduction:
Shree Ram Sealing Engineers is a trusted name in India’s industrial leak sealing and cold welding repair services. With years of experience in serving chemical plants, refineries, and manufacturing units, the company specializes in providing on-site solutions that minimize downtime and ensure safe operations.
Recently, Shree Ram Sealing Engineers successfully completed a critical glassline repair putty case study at Bayer Vapi, one of Gujarat’s leading chemical processing facilities. The project involved repairing a leaking glass-lined reactor using advanced cold welding techniques—without any hot work or plant shutdown.
Bayer Vapi is a prominent chemical manufacturing unit located in Vapi, Gujarat. The facility produces a wide range of specialty chemicals and pharmaceutical intermediates. Like most chemical plants, Bayer Vapi relies heavily on glass-lined reactors and vessels to handle highly corrosive acids and reactive chemicals.
Glass-lined reactors are essential in the chemical processing industry because they offer excellent corrosion resistance. The glass coating protects the underlying steel from acidic and caustic chemicals. However, any damage to this glass lining—whether from thermal shock, mechanical impact, or chemical attack—can lead to serious leakage and production losses.
During routine operations, the maintenance team at Bayer Vapi noticed a leak in one of their critical glass-lined reactors. The reactor was handling strong acidic chemicals, and the leakage posed both safety and operational risks.
Traditional repair methods like welding or dismantling the reactor were not feasible due to the following reasons:
- Hot work (welding) was strictly prohibited in the chemical zone
- Dismantling the reactor would require complete plant shutdown
- Long downtime would result in significant production loss
- Exposure to corrosive chemicals made manual repair difficult
The client needed a fast, safe, and reliable solution that could restore the reactor without stopping production or compromising safety standards.
The repair project came with several technical and operational challenges:
No Hot Work Allowed
Safety regulations at Bayer Vapi did not permit any welding or flame-based repair work inside the chemical processing area. This ruled out conventional repair methods.
Reactor Could Not Be Dismantled
The glass-lined reactor was integrated into a continuous production line. Removing or replacing it would have caused weeks of downtime and massive production losses.
Need for Fast Repair
The client required a solution that could be implemented quickly—preferably within a few hours—to avoid disrupting operations.
High Chemical Resistance Required
Any repair material used had to withstand continuous exposure to strong acids and corrosive chemicals without degrading or losing its bonding strength.
Understanding the urgency and complexity of the situation, Shree Ram Sealing Engineers deployed a team of experienced engineers to the Bayer Vapi facility for on-site inspection and repair.
After analyzing the leak location, reactor condition, and operating environment, the team recommended Glassline Repair Putty—a proven cold welding solution designed specifically for glass-lined reactor repair.
Step-by-Step Repair Process:
- Surface Preparation: The damaged area on the glass-lined reactor was carefully cleaned and degreased to ensure proper bonding.
- Application of Glassline Repair Putty: The putty was applied directly to the leak point using specialized tools. No heat or welding was required.
- Curing Time: The putty was allowed to cure as per manufacturer guidelines. The curing process created a strong, chemical-resistant seal.
- Quality Check: After curing, the repaired area was thoroughly inspected and tested for leak resistance and bonding strength.
- Reactor Restarted: The reactor was put back into operation within hours, with full confidence in the repair quality.
The entire repair was completed on-site without any plant shutdown or safety hazards.
Glassline Repair Putty has become the preferred choice for chemical reactor corrosion repair across India. Here’s why:
High Corrosion Resistance
The putty is formulated to resist strong acids, alkalis, and solvents commonly used in chemical processing.
Suitable for Acidic Chemicals
It offers exceptional bonding and durability even in harsh acidic environments.
Strong Bonding on Glass-Lined Surfaces
Unlike standard epoxy or putty, Glassline Repair Putty is designed specifically for glass-coated substrates.
Long Service Life
Once cured, the repair can last for years, reducing the need for frequent maintenance.
No Shutdown or Hot Work Required
The cold welding method eliminates fire hazards and allows repairs to be done in live chemical zones.
The glass-lined reactor repair at Bayer Vapi was completed successfully within the planned timeframe. The results were highly satisfactory:
- Leakage Completely Sealed: The leak was permanently stopped, and the reactor resumed normal operations.
- Reactor Restored to Full Capacity: No compromise in performance or chemical resistance.
- Improved Corrosion Protection: The repaired area showed excellent resistance to acidic chemicals.
- Minimal Downtime: The repair took only a few hours compared to weeks required for traditional methods.
- Significant Cost Savings: Avoided reactor replacement costs and production losses.
Client Satisfaction: Bayer Vapi appreciated the professional service and effective solution.
- No welding or heat-based repair
- On-site repair without dismantling
- Faster turnaround time
- Cost-effective solution
- Safe for chemical industry use
- Long-lasting and durable repair
- Zero production downtime
- Compliance with safety norms
