BOILER AND PRESSURE VESSEL CODE SECTION / DIVISION ASME Section 01 This Section provides requirements for all methods of construction of power, electric, and miniature boilers; high temperature water boilers, heat recovery steam generators, and certain fired pressure vessels to be used in stationary service; and power boilers used in locomotive, portable, and traction service. ASME Section 02 This section is divided into four parts covering the materials for the construction of piping and pressure vessels. • • • • Part A (Ferrous material), Part B (Non-ferrous material), Part C (Welding rods and electrodes) Part D (Material properties). Note: - Part D is used to get allowable stress value to calculate pressure vessel wall thickness at different design temperature. ASME Section 03 This section provides requirements for new construction of nuclear power system considering mechanical and thermal stresses due to cyclic operation. Deterioration, which may occur in service as result of radiation effects, corrosion, or instability of the material, is typically not addressed. Subsection NCA – General requirements for Division-01 / 02. Division-01 • • • • • • • • Subsection NB – Class-01 Components Subsection NC – Class-02 Components Subsection ND – Class-03 Components Subsection NE – Class-MC Components Subsection NF – Support Subsection NG – Core Support Structures Subsection NH – Class-01 Components Elevated Temperature Services Appendices Division-02 - Code of Concrete Containments Division-03 - Containments for Transportation and Storage Spent Nuclear Fuel and High Level Radioactive Material and Waste. • • • Subsection WA – General Requirement for Division-03 Subsection WB – Class TP (Type-B) Containment Subsection WC – Class SC Storage Containments Division-04 – Reserved for Fusion Reactors (Not Active) Division-05 – Construction Rules for High Temperature Reactors (Not Active) • • • • • • Subsection HA – General Requirements Subsection HB – Class-A Metallic Pressure Boundary Components Subsection HC – Class-B Metallic Pressure Boundary Components Subsection HF – Class A & B Metallic Supports Subsection HG – Class-A Metallic Core Support Structure Subsection HH – Class-A Non-Metallic Core Support Structure ASME Section 04 Part HG rules are restricted to steam-heating boilers for operation at pressures not exceeding 15 psi (Saturation temperature 250°F) (103 kPa) and to hot-water-heating and hot-water-supply boilers at pressures not exceeding 160 psi (1100 kPa) and/or temperatures not exceeding 250°F (121°C). ASME Section 05 This section is a reference code that deals with Non-destructive Examination (NDE) requirements, like Personal Qualification, Procedures, Equipment, Calibration and Demonstration of Non-destructive Examination (NDE) procedure. ASME Section 06 This section covers the rules for the care and operation of steam-heating boilers, hot-water-heating boilers, and hot-water-supply boilers. ASME Section 07 This section shows, Recommended Guide-Lines for the Care of Power Boilers, falls within the purview of the BPV Committee on Power Boilers (BPV I). The purpose of these Recommended Guidelines, as stated in the “Organization of Section 7” is; The purpose is to promote safety in the use of power boilers. ASME Section 08 This section benefits users, manufacturers, constructors, designers, and others, by providing highly detailed requirements for fired or unfired pressure vessel design, fabrication, assembly, erection, inspection, testing and certification. • • • Division-01: - Deals with regulations about the design, fabrication, inspection, testing, and certification of pressure vessels of pressure vessels that operate under internal or external pressures surpassing 15 pounds per square inch gauge (psig). These vessels could be either fired or unfired. Division-02: - The allowable stress is determined by considering various factors such as material properties, design conditions and safety margins. Unlike Division 1, which provides fixed allowable stress values, Division 2 allows for a more detailed and customized assessment of these factors. Division-03: - This Division provides requirements applicable to the design, fabrication, inspection, testing, and certification of pressure vessels operating at either internal or external pressures generally above 10,000 psi. Such vessels may be fired or unfired. ASME Section 09 This section specially addresses the qualification standard for welding and brazing procedures, as well as the qualification of welders and brazers. ASME Section 10 Fiber Re-enforced plastic pressure vessels (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). ASME Section 11 This section provides, standards for the examination, in-service testing and inspection, and repair and replacement of Nuclear Power Plant components, pressure vessels and piping. ASME Section 12 This section provides, rules that constitute requirements for construction and continued service of pressure vessels for the transportation of dangerous goods via highway, rail, air or water. ASME Section 13 This section contains rules that provide the requirements for the overpressure protection of pressurized equipment such as boilers, pressure vessels, and piping systems. Overpressure protection methods include: Releasing excess pressure by use of pressure relief devices. Note:• • 02 Code Cases are available for BPVC as well. ASME Boiler and Pressure Vessel Code, is made of 13 sections and contains over 15 divisions and subsections.
