This mesmerizing footage captures the millimeter-precision technique—the 2-meter pry bar flexing the outer shell's fiberglass layers like an accordion, expanding the diameter by exactly 8cm for precisely 90 seconds—just long enough for the inner liner to slide home. Witness how the workers use the pipe's own spring tension to achieve perfect realignment.
The Nesting Process:
Expansion Mapping: Identifying optimal flex points
Temporary Distension: 8cm diameter increase
Liner Insertion: 45-second installation window
Why This Method Triumphs:
✔ Preserves 100% insulation R-value
✔ Eliminates need for destructive cuts
✔ Enables perfect vapor barrier continuity
Artisan's Secrets:
⚠ Heat pry tools to 60°C for material memory
⚠ Apply food-grade wax to insertion guides
⚠ Hum at 330Hz to detect stress harmonics
Final Thought:
This isn't just assembly—it's the ballet of industrial symbiosis, where every temporary deformation creates permanent thermal perfection.
