Cylinder hydro testing is an important part of all vehicle maintenance. It’s a check-up on the cylinder that takes place according to the specified time. It should not be delayed as it could increase the risk of vehicle damage and even death. According to the Delhi transport authority, it is necessary.
The Delhi transport authority approved these service centers. They provide services such as CNG Cylinder hydro-testing, CNG cylinder Testing in Delhi, and the fitting kit for the cylinder. The vehicle department must test every cylinder. This helps to maintain the cylinder’s good condition.
Service centers keep track of all details about the cylinder, including durability, corrosion, structural flaws, and leaks. This information is used to determine the condition of your cylinder. To ensure that the cylinder is in good shape, the supervisor inspects it internally and externally.
The CNG Cylinder Hydro Test in Delhi is a different type of check-up. It uses a different procedure. This procedure involves filling the cylinder with liquid to verify structural flow, leakage, and other problems. It is safe and available at reasonable prices.
However, ensure that you take the cylinder to the service center. This will allow them to verify that the cylinder is working smoothly and has not caused any problems.
What is Hydro Testing of CNG Cylinder Cylinders?
Hydrostatic Testing is a nondestructive method to inspect cylinders for corrosion, structural flaws, and leaks. The following procedure checks the integrity of the cylinder’s structure. This process checks the cylinder’s pressure handling strength. Hydrotesting is filling a cylinder with water and applying heavy pressure to it using a high-pressure pump. Leakage will be detected if the cylinder has a low capacity. These cylinders should be thrown away immediately and not used.

What are the steps taken during Testing?
Hydro Testing includes the following steps:
- De-pressuring and Degassing the Cylinder
- Valve opening and internal inspection
- Cleaning and drying the cylinder internally
- Ultrasonic Thickness Test of the Cylinder Wall
- Hydrostatic Stretch Testing of the Cylinder
- Cleaning the cylinder from both the inside and outside.
- The Cylinder’s Tare Weight should be checked
- External / Internal Inspection
- Fixation of the Cylinder to the Vehicle/Cascade
- Provide a Testing Certificate for the Cylinder
Why is it Important?
CNG cylinders can withstand high pressure because they are constructed and designed in such a manner. CNG cylinders can be used safely as they have been manufactured according to specific requirements. They are also tested following international standards and specifications. These cylinders are equipped with a safety burst disc that releases pressure in the event of high-pressure/high temperatures at filing or any other time. CNG cylinders can be made from a special steel alloy and are seamless in design. They are compact enough to fit in small vehicles due to their size. To ensure 100% safety, CNG cylinders must be retested according to Indian Standard 8451, Gas Cylinder rules & CCOE guidelines.
Hydrostatic Testing can inspect cylinders for corrosion, structural flaws, and leaks. It’s used to verify a cylinder’s structural integrity. The testing process involves enclosing a filled cylinder inside a water-filled test jacket. The cylinder expands when pressure is applied to it internally. The total and permanent volumetric expansions are measured by measuring how much water is displaced from the cylinder under pressure and after it has been released. A visual inspection is done on the cylinder’s exterior and interior.
