Glass Inspection & Repair Services for Glass‑Lined Reactors
ZAIN—Your Consultant for Glass-Lined Reactor Solutions
Is your glass-lined reactor operating safely and efficiently? ZAIN provides professional inspection and repair services for glass-lined reactors, tanks, and accessories. Our certified technicians use industry-standard methods—spark testing, thickness measurement, visual inspection, and, if needed, full reglass restoration—to verify liner integrity and extend equipment life. We deliver detailed diagnostics and execute repair or reglass solutions on-site or in our partner facilities, ensuring compliance and operational reliability.
Preventive Maintenance & Condition Monitoring
Scheduled annual inspection programs are recommended to detect early signs of wear. We provide inspection checklists covering agitating nozzles, gaskets, baffle surfaces, electrical seals, and external jacket condition. Implementing preventive checks can help avoid permanent lining damage and extend reactor life by years.
Accessories & Mechanical Seal Assessment
Glass inspection is only one part—our service also covers accessories critical to performance:
- Agitators, baffles, drive seals, and mechanical seals
- Gaskets, drive collars, flush valves, and nozzles inspected for wear or corrosion
- Evergear reducers and gear mechanisms are evaluated to ensure proper torque transmission and alignment (note: many lining failures initiate near moving parts).
On-Site Glass Lining Repair & Reglassing
Small defects such as chips or pinholes can often be repaired on-site using methods like tantalum plugs, PTFE sleeves, or patches. If more extensive damage exists, reglassing (removing existing lining, substrate repair, and refiring new glass) can restore vessel integrity. Reglassed reactors meet or exceed new-vessel standards and retain warranty coverage.
Safety & Compliance Protocols
All inspection and repair work is performed following OSHA confined-space standards, with documented risk assessments and operability testing. Thermal shock, vacuum loading, and pressure limits are observed carefully—especially during startup and spark testing. Our team provides certified safety documentation and inspection logs for cGMP or FDA compliance.
Frequently Asked Questions
Who is ZAIN Industries?
ZAIN Industries is a leading expert in industrial mixing solutions. We specialize in providing consulting services, business development strategies, and comprehensive guides for both static and dynamic mixing equipment.
What does glass lining inspection involve?
We perform visual inspections to identify cracks or chips, spark (holiday) testing to detect micro-defects, and thickness measurements to check for wear or erosion. We compile all results in a maintenance log for long-term tracking and compliance.
How often should inspections be conducted?
We recommend annual inspections as part of your preventive maintenance program. Some high-use or corrosive-process systems may require check-ins every 6 months to avoid unexpected failures.
What repair methods do you offer?
Minor defects can often be fixed with on-site patch plugs, sleeves, or PTFE repairs. For severe wear or damage, we offer full reglassing services that restore vessels to like-new quality while often reducing cost compared to full replacement.
Can seals and agitator components be checked during inspection?
Yes. Our inspections cover agitator shafts, drive seals, baffles, nozzle connections, and gaskets. We'll identify worn or corroded elements and recommend replacements or adjustments to avoid further liner damage .
Is your inspection service compliant with safety regulations?
All services comply with OSHA confined-space entry, lockout/tagout, and process safety protocols. We document every step to support regulatory requirements such as FDA or cGMP audits.
What is the timeline for inspection and repair?
Standard on-site inspections with minor on-site repairs can be completed within a day or two. If reglassing is needed, total turnaround is typically several weeks, significantly faster than sourcing new equipment .
Can a vessel be refurbished rather than replaced?
Yes—if the steel substrate is in sound condition, reglassing is often the most cost-effective solution. It restores full functionality at around 60‑70% of the cost of new equipment and preserves existing infrastructure .
When is a reactor not a candidate for repair?
If the steel shell has advanced corrosion, structural damage, or if capacity needs changes, replacement may be preferable. Our inspection report includes a technical recommendation to guide decision-making.
