Texas Compressed Natural Gas (CNG) Delivery Truck Driver Practice Exam

The minimum rated service pressure for vapor recovery receivers is set at 250 psig. This specification ensures that vapor recovery systems can effectively manage the pressures typically encountered during operation without risking failure or safety hazards. A rating of 250 psig allows the equipment to handle the range of pressures that may arise when gas is being recovered and processed, which is critical for maintaining operational integrity and preventing leaks or failures. This pressure rating is particularly important in environments where vapor recovery systems are utilized to capture and recycle vapors from tanks and other sources, as it directly relates to their ability to perform under various operational conditions without compromise. Setting the minimum rated service pressure at this level aligns with standard industry practices and regulatory requirements designed to promote safety and efficiency in gas handling operations.
