In 1974 ASME published Section X of the Boiler and Pressure Vessel Code to ensure safe Fiber Reinforced Plastic pressure vessels. This code required that a test vessel be made exactly as the intended vessel, the test vessel was over pressured to destruction to demonstrate the safety of the design and fabrication of the vessel. The production could proceed. Many small vessels for air, pure water, etc. were fabricated. However, if a single tank was desired for atmospheric pressure, this code was not applicable nor economical.
SECTION X – FIBER-REINFORCED PLASTIC PRESSURE VESSELS
Provides requirements for the construction of a fiber-reinforced plastic pressure vessel (FRP) in conformance with a manufacturer’s design report. It includes production, processing, fabrication, inspection, and testing methods required for the vessel. Section X includes three Classes of vessel design: Class I and Class III – qualification through the destructive test of a prototype; and Class II – mandatory design rules and acceptance testing by nondestructive methods. These vessels are not permitted to store, handle or process lethal fluids. Vessel fabrication is limited to the following processes: bag molding, centrifugal casting and filament-winding, and contact molding. Rules pertaining to the use of the single ASME certification mark with the RP designator are also included.
