CNG cylinder hydro testing is a critical safety procedure that ensures the structural integrity and safe operation of cylinders used in CNG vehicles. The accuracy of this testing depends heavily on the quality of equipment and calibration standards used during the process. At Jilu Auto Gas, we use advanced, calibrated, and government-compliant equipment to ensure precise, reliable, and safe testing results for every CNG cylinder.
Our facility is equipped with professional hydro testing systems, calibrated gauges, inspection tools, and handling equipment that meet safety and regulatory requirements.
High-Precision Hydro Testing Pump and Pressure Gauges
At Jilu Auto Gas, we use an advanced air hydro pump system designed for precise pressurization of CNG cylinders. This system is fitted with two high-quality 150 mm diameter pressure gauges that provide accurate pressure readings during hydro testing.
These gauges offer an accuracy level of ±0.1%, ensuring precise monitoring of pressure changes during testing. Our volumetric measuring equipment follows approved standards and is capable of detecting very small permanent volume changes in the cylinder, up to 1/20,000th of its total water capacity. This level of accuracy ensures reliable identification of cylinder strength and safety.
Calibrated Hydraulic Pressure Gauges
To ensure reliable pressure measurement, Jilu Auto Gas uses hydraulic pressure gauges with a capacity range of 0 to 700 kg/cm². These gauges are regularly calibrated against master pressure gauges with a range of 0 to 400 kg/cm² and an accuracy of ±0.5%.
This calibration process ensures that all pressure readings are precise and meet government safety requirements. Accurate pressure measurement is essential to determine whether a cylinder can safely withstand operational pressure.
Internal Cylinder Inspection Using Low Voltage Lamps
At Jilu Auto Gas, internal inspection of cylinders is performed using extra low voltage inspection lamps. These lamps allow our technicians to safely examine the inside of the cylinder without risk.
This inspection helps identify:
- Internal corrosion
- Cracks or structural defects
- Surface damage
Early detection of these issues helps prevent potential safety risks.
Professional Measurement Tools and Inspection Equipment
Our facility uses straight edge templates, gauges, and specialized hand tools to measure and inspect the cylinder’s external and internal condition.
These tools help our technicians detect:
- Surface irregularities
- Structural deformities
- Physical damage
This ensures that only cylinders in safe condition are approved.
Accurate Cylinder Weighing Using Calibrated Weighing Machines
At Jilu Auto Gas, we use a high-capacity platform weighing scale capable of measuring cylinders accurately with an accuracy level of 1.0%.
Additionally, we use certified standard test weights approved and stamped by the Weights and Measures Department to ensure proper calibration of our weighing machines.
This allows us to detect any loss of material from the cylinder, which could indicate corrosion or structural weakness.
Professional Cylinder Handling Equipment
Safe handling of cylinders is an important part of the testing process. At Jilu Auto Gas, we use specialized cylinder handling equipment, including:
- Cylinder holding vise
- Valve opening spanner sets
- Professional cylinder handling tools
These tools ensure safe and secure handling of cylinders without causing damage during testing.
Cylinder Draining and Drying Equipment
After hydro testing, proper drying of the cylinder is essential. At Jilu Auto Gas, we use professional cylinder draining and drying systems.
Our process includes internal purging using dry and hot gases such as nitrous oxide and oxygen to ensure complete removal of moisture from inside the cylinder.
This prevents internal corrosion and ensures the cylinder remains in safe working condition.
Cylinder Marking and Stamping Equipment
At Jilu Auto Gas, we use professional marking and stamping equipment to mark cylinders after successful testing.
This includes:
- Number marking systems
- Company monogram stamping
- Official test identification marks
Each cylinder is marked with:
- Cylinder identification
- Testing approval
- Next test due date
This ensures traceability and compliance with safety regulations.
