Some information about CNG type IV
The global type 4-cylinder market size was valued at USD 279.31 Million in 2021 and is expected to grow at a CAGR of 7.46% during the forecast period. However, India’s type 4-cylinder market is projected to reach USD 23.11 Million by 2030 at a growth rate of 7.73%

Based on cylinder type, the global type 4-cylinder market is classified into CNG, biogas, hydrogen, and LPG. The CNG segment generated USD 131.50 million in revenue in 2021 and is expected to reach USD 240.24 million by 2030 with a CAGR of 7.11% during the forecast period, 2022-2030. The segment’s growth is attributed to Type 4 CNG Cylinders, typically around 70% weight reduced over Type 1 and 2 Steel cylinders and 5% to 35% weight reduced over Type 3 Aluminum liner-based cylinders because of the presence of lightweight HDPE liner. The Type 4 cylinders have higher Class pressure withstanding capacity when compared with Type 3 cylinders.

• Better Safety: Type-IV CNG cylinders are made of composites, not metal, so they are safer. If they leak, gas escapes slowly through layers, giving a warning and stopping sudden explosions.
• Lighter Weight: These cylinders are much lighter than metal ones. This makes the vehicle lighter, which helps it use less fuel and handle better on the road.
• Strong and Tough: Type-IV cylinders have different wall thicknesses that make them very strong and tough. They can handle high pressure and many refueling cycles without breaking easily.
• Good for the Environment: CNG is cleaner than petrol and diesel, cutting down on pollution. These cylinders help store and use CNG safely, making cars greener.
• Special Materials: The cylinders have a polyethylene liner inside, a composite shell outside, and aluminum flanges. These materials make the cylinders last long and resist rust.

Interesting fact: Refueling: How drivers refuel can affect the life of these cylinders. Bad habits like overfilling can reduce the cylinder’s life by up to 78%, so refueling properly is important.
