What is the benefit of using composite cylinders as per standards?

Using composite cylinders presents significant advantages, particularly regarding the reduced risk of corrosion. This is primarily because composite materials, which typically consist of a polymer matrix reinforced with fibers such as carbon or glass, do not rust like traditional steel or aluminum cylinders when exposed to various environmental conditions.

Corrosion can lead to structural integrity issues over time, making cylinders unsafe for storage and transport of compressed natural gas. The non-corrosive nature of composite materials enhances safety by maintaining the integrity of the cylinder for a longer period, as they resist deterioration caused by exposure to moisture, chemicals, and harsh weather conditions. This durability not only extends the usable life of the cylinder but also minimizes the need for frequent inspections and replacements, contributing to overall safety and reliability in CNG applications.

While other options might present valid considerations related to composite cylinders, such as their potential for a longer lifespan, those benefits are closely tied to the corrosion resistance aspect, which directly addresses longevity and safety concerns.
