Quality Control

Metallographic Analysis: Ensuring 100% copper purity and optimal brazing penetration.

Salt Spray Testing: Validating anti-corrosion performance for harsh climates.

Tensile Strength Testing: Guaranteeing structural integrity under extreme mechanical stress.

Pressure & Leakage Testing: 100% pressure holding tests to ensure zero refrigerant leakage.

Cleanliness Inspection: Preventing internal blockages by ensuring residue-free inner pipe surfaces.

Helium Mass Spectrometer: High-precision micro-leak detection ensuring zero refrigerant loss.

2D Optical Measurement: Strict dimensional inspection for pipe diameters and flaring angles.

Microscopic Inspection: Evaluating surface finish and micro-structures of brazed joints.
