According to the ASME Code, what is the minimum pressure for a hydrostatic test of a compressed air bottle?

The minimum pressure for a hydrostatic test of a compressed air bottle, according to the ASME Code, being set at 150% of the maximum operating pressure ensures an adequate safety margin during testing. This approach confirms that the bottle can withstand pressures beyond its normal operating conditions without failure. Hydrostatic testing is crucial as it subjects the bottle to conditions that simulate extreme stress to identify any weaknesses or defects in the material or construction.

Testing at 150% of the maximum operating pressure provides an essential verification step to enhance safety in operation. It ensures that even if there are minor imperfections or fatigue in the material, the bottle can operate safely under its designated parameters. This standard helps in maintaining the integrity of pressure vessels and reduces the risk of catastrophic failure during actual use, ensuring safety for personnel and equipment alike.
