ASME Section X provides requirements for construction of an FRP pressure vessel in conformance with a manufacturer’s design report. It includes production, processing, fabrication, inspection and testing methods required for the vessel. ASME 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. General specifications for the glass and resin materials and minimum physical properties for the composite materials are given.

For vessels fabricated in accordance with these rules, the provisions of ASME Section X shall apply over any other sections of the Code. When metallic components are part of fiber‐reinforced plastic vessels, they shall meet the provisions of ASME Section VIII Division 1.

What are the key changes for ASME BPVC Section X 2023?

  • Clarified service life requirements for Class III vessels, in 8-100.6, to indicate that the service life for glass fiber reinforced vessels is limited to 20 years, but the maximum service life is not limited for carbon fiber reinforced vessels.
  • In 8-700.5.8, other leak test methods for Class III vessels that may be more reasonable and cost effective, but still yields satisfactory results, based on experience to date, are now permitted.
