Quality Testing Process
Raw Material Testing
Every batch of polymer compound is tested for purity, hardness, and melt index before extrusion.
Air Pressure Testing
Burst pressure and working pressure tested at multiple temperature points per international standards.
Dimensional Accuracy
OD, ID, and wall thickness verified with laser micrometers across the full coil length.
Long-term Durability
Accelerated ageing, ozone exposure, and flex-fatigue tests for product life validation.
