Texas CNG(Compressed Natural Gas) Driver Practice

Pressure vessels and other containers must adhere to regulations under which code?

1. ASME Boiler and Pressure Vessel Code

2. DOT FRP1 standard

3. CGA S-1.1 specifications

4. DOT 3AA specifications

The correct answer is: ASME Boiler and Pressure Vessel Code

Pressure vessels and other containers used in the transportation of compressed natural gas must adhere to regulations set forth by the ASME Boiler and Pressure Vessel Code. This code is crucial because it provides the necessary guidelines for the design, fabrication, inspection, and testing of pressure vessels, ensuring their safety and integrity during use. The ASME code encompasses various aspects such as material properties, design calculations, fabrication techniques, and the necessary quality assurance processes. Complying with this code helps prevent accidents and failures in pressurized systems, which is essential in transporting hazardous materials like CNG. While other standards and specifications, such as DOT FRP1, CGA S-1.1, and DOT 3AA, address certain aspects of pressure containment and safety, the comprehensive coverage of pressure vessels under the ASME code is what makes it the primary regulation applicable in this context. Thus, adherence to the ASME Boiler and Pressure Vessel Code is critical for all entities involved in the design and operation of such equipment.
