Why Is CNG Cylinder Hydro Testing Very Important?


We are all aware of the rise in petrol and diesel prices in India over recent years. CNG is becoming more popular as people either install CNG kits or convert their cars to run on compressed gas. CNG vehicles can be a great way to save money, but there are important things you need to do when using CNG. We will be discussing CNG Cylinder Hydro Testing in this blog.

CNG Cylinder Hydro Testing

Hydrostatic testing, also known as Hydro testing, 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. Hydro testing is the process of 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.

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 not able to withstand 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, as 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 at the gas stations or other penalties.

Safety is paramount as your CNG cylinder will be subject to thousands of pounds of pressure during refueling. The constant stretching of the cylinder wall results in cracking in the metal and it can no longer bear the pressure and explodes. It is therefore crucial to test your cylinder.  CNG cylinder hydro testing involves the technicians inspecting your cylinder both internally and externally to make sure that it is safe enough to withstand the pressure of refueling. The clients receive a certificate of compliance after completing the test. This allows them to refill their cylinders at any gas station.

Safety Being the Ultimate Goal

Hydro Testing is essential to avoid accidents like explosions in cylinders and the increasing number of CNG vehicles. Hydro Testing is vital for your safety and your life. CNG cylinders are subject to significant pressure when they are refueled. The constant pressure applied to the walls causes cracks in metal that cannot withstand the pressure and explodes. Hydro Testing is required to avoid such dangerous situations.

CNG cylinders are becoming more popular in modern applications because they are safe and reliable for both the vehicle and the environment. CNG can be used to reduce pollution and combat the negative effects of Diesel and Petrol fuels.

This will allow you to learn more about the vehicle and make sure that your CNG cylinder works well. You will be able to enjoy trouble-free driving. Safety is the number one priority when it comes to malfunctioning vehicles. Prevention is better than treatment. You can ensure the safety of your CNG cylinders by conducting a thorough inspection.
