ASME Boiler and Pressure Vessel Code

ASME's Boiler and Pressure Vessel Code controls the design, inspection, and repair of pressure vessels. The ASME B&PV Code has adopted the use of many ASTM NDT standards and practices. The ASTM documents are re-identified with a "S" preceding the "E" in the B&PV Code. For example, E-94 would become SE-94. NDT personnel are primarily concerned with the followings sections of the B&PV Code.

• Boiler and Pressure Vessel Code, Section V-Nondestructive Examination
  This Section contains requirements and methods for nondestructive examination which are referenced and required by other code Sections. It also includes manufacturer's examination responsibilities, duties of authorized inspectors and requirements for qualification of personnel, inspection and examination. Examination methods are intended to detect surface and internal discontinuities in materials, welds, and fabricated parts and components.
• Boiler and Pressure Vessel Code, Section VIII- Rules For Construction of Pressure Vessels Division 1
  This Division of Section VIII provides requirements applicable to the design, fabrication, inspection, testing, and certification of pressure vessels operating at either internal or external pressures exceeding 15 psig. Such pressure vessels may be fired or unfired.
• Boiler and Pressure Vessel Code, Section VIII-Rules For Construction Of Pressure Vessels Division 2-Alternative Rules
  This Division of Section VIII provides requirements applicable to the design, fabrication, inspection, testing, and certification of pressure vessels operating at either internal or external pressures exceeding 15 psig. Such vessels may be fired or unfired.
• Boiler and Pressure Vessel Code, Section X-Fiber-Reinforced Plastic Pressure Vessels
  This Section 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.
• Boiler and Pressure Vessel Code, Section XI - Rules For Inservice Inspection Of Nuclear Power Plant Components
  This Section contains Division 1 and 3, in one volume and provides rules for the examination, inservice testing and inspection, and repair and replacement of components and systems in light water cooled and liquid metal cooled nuclear power plants.
• B16.34 Valves Flanged Threaded And Welding End
  This standard applies to new valve construction and covers pressure-temperature ratings, dimensions, tolerances, materials, nondestructive examination requirements, testing, and marking for cast, forged, and fabricated flanged, threaded, and welding end, and wafer or flangeless valves of steel, nickel-base alloys, and other alloys.
