What is Hydro Testing of CNG Cylinder Cylinders?
Hydrostatic Testing, also known as Hydrostatic Testing or CNG Leak Test, is a non-destructive 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
- Inspections: Internal and External
- Fixation of the Cylinder to the Vehicle/Cascade
- Provide a Testing Certificate for the Cylinder
Why is CNG Hydro Testing important
Hydro Testing is essential to prevent mishaps like cylinder explosions. Hydro Testing is essential for your safety and that of your family. CNG cylinders are subject to a lot of pressure during refueling. Constant pressure on the cylinder walls causes a crack in metal that is no longer able to handle the pressure and eventually explodes. Hydro Testing is required to avoid these dangerous situations.
CNG vehicles must have their CNG Hydro-tested every three years, per Indian Standards 8451:200 & Gas Cylinder Rules (2004). A certificate of compliance is issued to the customer after the test. This certificate must be attached to the proper place. This certificate is required to refuel the cylinder at any authorized gas station. Failure to adhere to these requirements can result in refusal to fill gas stations or other penalties.
Where can I get my cylinders tested and certified? What’s the approximate cost of a cylinder?
Hydro Testing can be done using PEST and Government Approved CNG Testing Pumps. Find out which Hydro Testing Pumps are approved. Although the approximate cost of Hydro Testing can vary from location to location, it is usually between Rs.1200 and Rs.3000.
CNG is a cleaner, more sustainable and greener fuel that you can switch to. This will help us all contribute toward a bright future. You can ride to a greener future by getting your vehicle Hydro-tested with approved pumps.
Conclusion
You cannot delay it as negligence could increase the danger.
To eliminate fire hazards, it is recommended that your CNG cylinder hydro testing be done each year. The Testing also helps to ensure that CNG is being used correctly and maintains a steady flow. This test is very affordable and does not cost a lot of money.
