Prepping Damaged Equipment

Two Samples Permanently Repaired

After years of internal research and rigorous testing, our innovative solution is ready to redefine industry standards.

Glasslined Technologies Inc. (GTI) has successfully completed an extensive two-phase evaluation of its patented Permanent Glasslined Repair Technology, setting a new benchmark for repairing glass-lined equipment. GTI did not collaborate with the Materials Technology Institute (MTI). All testing and development were conducted in-house at GTI, from initial concept through the successful completion of ASTM B08.12 testing.

This groundbreaking repair method offers a permanent solution, unlike traditional temporary fixes that require on-site intervention. GTI’s approach significantly reduces downtime and cost while maintaining the operational integrity of critical process equipment.

Phase 1: Non-Destructive Evaluation (NDE) Techniques Demonstrate Promising Results

The first phase focused on evaluating repairs using advanced NDE methods. A Level 3 NDE technician from Dow Corning led the testing, which included:

  • Ultrasonic (UT) thickness measurements

  • 6000VDC spark testing

  • Statiflux evaluation

  • Ultra-sensitive fluorescent penetrant testing (PT)

  • Visual inspections (naked eye and USB microscope)

  • Dolly pull-off adhesion testing

  • Compression testing in bolted joint assemblies

These methods ensured a comprehensive assessment of the repaired glass surfaces.

Key Findings:

  • All test areas passed NDE, confirming their structural integrity.

  • Visual inspections revealed seamless blending between original and repaired glass—particularly striking on white glass with blue repairs.

  • Penetrant testing identified some porosity in both the original and repaired glass.

  • Dolly pull-off tests showed adhesive failure, indicating that the bond strength of the repaired glass surpassed that of the adhesive itself.

  • Compression testing showed no damage until the seating stress exceeded 5 ksi, proving the durability of the repair.

Phase 2: Performance Testing in Corrosive and Abrasive Conditions

Phase 2 moved from structural integrity to real-world performance. Test samples were evaluated at Alfred University under ASTM B08.12 standards.

Sample Preparation:
12 sample coupons were supplied by a major OEM for induction testing. Six coupons had small areas repaired using GTI’s proprietary method. After repairs were completed, all coupons were shipped to Alfred for analysis. The remaining six served as control samples.

Test Conditions & Results:

  • Corrosion Resistance:

    • In 20% hydrogen chloride at 100°C for 132 hours, the repaired glass showed 300 microns of corrosion vs. 100 microns in control samples.

    • In 50% sodium hydroxide at 50°C for 1060 hours, the repaired glass outperformed the controls (350 microns vs. 375 microns of corrosion).

  • Thermal Shock Resistance:

    • Samples exposed to 320°F and immediately submerged in ice water showed no signs of spalling, cracking, or damage.

  • Abrasive Loop Testing:

    • In modified G174-22 loop testing, repaired glass exhibited weight loss within the standard deviation of the control group.

    • Microscopic examinations confirmed no structural or visual differences between test and control samples.

Conclusions & Considerations

Repaired glass consistently matched the performance of control samples in all tests. However, several considerations remain:

  • Further testing in specific chemical environments may be required for certain industrial applications.

  • Results are most applicable to flat or concave surfaces; convex surfaces may introduce greater complexity.

  • Materials and processes used in this evaluation reflect a decade of R&D; GTI recognizes that advancements may have occurred since the original testing.

Results & Access
