CNG Cascade

Product Description

Cylinder Type and Quantity:

Specifies the type of CNG cylinders used (e.g., Type I, Type IV) and the number of cylinders in the cascade. For example, a cascade might consist of 40 cylinders, each with a 75-liter water capacity.

Water Capacity:

The total water capacity of the cascade, often expressed in liters (e.g., 3000 WL, 4500 WL), indicates the amount of CNG the cascade can hold.

Working Pressure:

The pressure at which the CNG is stored and used, typically 250 bar for many applications.

Test Pressure:

The pressure to which the cascade is tested to ensure its integrity, usually higher than the working pressure (e.g., 400 bar).

Material and Construction:

Details about the materials used for cylinders, piping, valves, and the supporting frame. Often includes specifications for stainless steel (e.g., SS316L) and other materials.

Safety Features:

Includes specifications for pressure relief valves, pressure gauges, temperature gauges, and bleed valves to ensure safe operation.

Mounting and Configuration:

Specifies how the cascade is mounted (e.g., on a truck, as a stationary unit) and the configuration of the cylinders (e.g., single bank, multiple banks).

Performance Standards:

Includes compliance with relevant standards like IS: 7825 (Part 2):2017, Gas Cylinder rules 2016, and PNGRB guidelines.

Corrosion Protection:

Specifies the type of paint and treatment to protect the cascade from corrosion, including fade-free life and resistance to UV damage.

Accessibility:

Details about access to filling and decanting ports, as well as access to cylinder valves.

Testing and Certification:

Includes requirements for cylinder testing and certification, often by a regulatory body like PESO (Petroleum and Explosives Safety Organisation).
