车用CNG全复合材料气瓶具有重量轻、抗腐蚀性能强、制造成本低等显著优点,因此在我国四川、重庆、北京等地,该气瓶曾广泛应用于出租车、公交车上。但由于其自身质量、使用管理不够规范等原因,造成该类气瓶在国内发生过几起重大的安全事故,使得该类气瓶在一些省市被禁用。北京市公交车用CNG全复合材料气瓶由于管理严格、安装位置有利等原因,目前使用安全状况相对良好,大批CNG全复合材料气瓶仍应用于城市交通中。
CNG composite car cylinders with gas cylinders have the advantages of light weight, strong corrosion resistance and low manufacturing cost. Therefore, in China’s Sichuan, Chongqing and Beijing, the cylinders have been widely used in taxis and buses. However, due to its own quality, the use of management is not standardized and other reasons, resulting in such gas cylinders in the country have had several major accidents, making this type of cylinder was banned in some provinces and cities. Due to strict management and favorable installation location, the CNG composite gas cylinders for buses in Beijing are relatively safe to use at present. A large number of CNG composite gas cylinders are still used in urban traffic.
