27)Type 1 the traditional steel cylinder

Type 1 CNG cylinders, also known as traditional steel cylinders, are one of the common types of CNG cylinders used in vehicles. Here are some key characteristics of Type 1 CNG cylinders:

Construction: Type 1 cylinders are typically made of high-strength steel. They consist of a steel liner or tube wrapped with layers of resin-impregnated continuous filament windings, usually made of fiberglass or other composite materials. The steel liner provides structural strength, while the composite layers offer additional reinforcement.

Pressure Rating: Type 1 cylinders are designed to withstand high-pressure conditions, typically ranging from 200 bar (2,900 psi) to 250 bar (3,600 psi) or higher, depending on the specific application and regulatory requirements.

Weight: Type 1 cylinders tend to be heavier compared to some other types of CNG cylinders due to the use of steel. The weight can vary depending on the cylinder’s size and capacity.

External Protection: Type 1 cylinders usually have an external protective coating or paint to provide corrosion resistance and enhance durability.

Inspection and Testing: Type 1 cylinders undergo rigorous testing and certification procedures to ensure compliance with safety standards. These include hydrostatic testing, ultrasonic thickness testing, and visual inspections to assess the integrity and condition of the cylinder.

Common Use: Type 1 cylinders have been widely used in CNG vehicles, especially in older or traditional vehicle models. They are known for their durability and reliability.

Compatibility: Type 1 cylinders are compatible with various CNG vehicles and can be used in different types of applications such as cars, buses, trucks, and other commercial vehicles.

Safety Considerations: Proper installation, handling, and maintenance are crucial for ensuring the safe use of Type 1 cylinders. It’s important to follow manufacturer guidelines, local regulations, and best practices for cylinder installation, inspection, and maintenance.

While Type 1 cylinders have been used extensively in the past, newer types of CNG cylinders, such as Type 2, Type 3, and Type 4, have gained popularity due to their lighter weight and improved capacity. However, Type 1 cylinders are still in use and continue to provide a reliable and cost-effective option for CNG storage in vehicles.
