Process Flow

Step-by-Step Inspection Flow

1
Visual Inspection

The cylinder is carefully examined for dents, corrosion, cracks, or any physical damage that may compromise safety.

2
Hydrostatic Testing

Using the water jacket method, the cylinder is filled with water and pressurized to test for leaks and measure volumetric expansion, ensuring structural integrity.

Ultrasonic Thickness Measurement

Advanced ultrasonic equipment is used to measure the wall thickness of the cylinder, detecting any thinning that could weaken the cylinder over time.

3
Valve Inspection & Leak Test

Valves are thoroughly checked and tested for airtight seals. Moisture and contaminants are removed, and the cylinder is inspected for any gas leaks before certification.

4
