A recently approved Code Case allows a flat-ribbon wound layered pressure vessel technology developed in China to be used for building and stamping pressure vessels within the bounds of the ASME Boiler and Pressure Vessel Code. Section VIII. Division 1. This paper illustrates using the rules of this Code Case when designing such a ribbon wound vessel for a typical process plant size application. Over 7000 flat-ribbon wound pressure vessels have been buih and operated in China with no reported catastrophic incidents. In addition to an enviable safety record, this manufacturing concept has been shown to have economic advantages that offer a new viable option for process plant developers worldwide.
