Re: Liquid gas container inspection
Dear Mr Trong My

AE testing would be a well suited technique. It provides integral monitoring of liquid gas containers with a limited number of sensors, it provides detailed information about the status of the container, it can show you areas of potential problems, and no scanning is required.
We from Vallen-Systeme provide top-quality AE equipment. For more information contact NDT Instruments in Singapore (NDTINST@mbox2.singnet.com.sg)or see our website www.vallen.de

Regards
Jens Forker

Re: Liquid gas container inspection
You need to be a little specific about the type and range of gas cylinders. Are we talking Industrial Type Compressed Gases or Typical Small Domestic LPG Cylinders.

Each will have specific requirements.

For compressed Gas Cylinders you may want to look at the American Compressed Gas Association Guidelines.

What you want to achieve from the inspection and the criticality of application dictates the inspection method.

If you want to do wall measurement in critical cylinders you may want to use an automated screening system using ultrasonic guided waves.

If you wish to monitor hydrostatic tests then the Acoustic Emission Method is well documented Refer To Journal Of Pressure Vessel technology May 1988 Vol 110.
Acoustic Emission Testing & Structural Evaluation Of Seamless Steel Tubes For Compressed Gas Cylinders ASME Vol 108 May 1986 pp 234-240
Materials Evaluation Nov 1987

There is a whole host of references. If you define the scope I am sure there is already standard answers available.
