Section 1

Konstruktion Dampfkessel
Section I of the ASME Boiler and Pressure Vessel Code provides rules for the construction of power boilers, electric boilers, miniature boilers, and high-temperature water boilers used in stationary, locomotive, portable, and traction service. Superheaters, economizers, and other pressure parts connected to the boiler without intervening valves are part of the boiler, and shall be manufactured per the requirements of the Code. Included in the scope of this Code are those pressure vessels in which an organic fluid is vaporized by heat from the combustion of fuel.
Requirements for specific valves, gauges, and fittings, (such as safety valves, water level gauges, feedwater valves, etc.) are included in this Code. The Code boundary extends up to and including the valves separating the boiler and superheater from steam pipes to other equipment, water supply pipes, drain pipes, and pipes to the surrounding atmosphere.

Heizkessel
Section IV of the ASME Boiler and Pressure Vessel Code provides rules for the construction of steam heating, hot water heating, hot water supply boilers, and potable water heaters. The boilers are direct fired or electrically heated. Section IV steam boilers are limited to 15 psi (1 bar), and the hot water heating and hot water supply boilers are limited to 160 psi and/or temperatures not exceeding 250° F.

Section VIII
Div.1

Konstruktion Druckbehälter
Section VIII, Division 1 of the ASME Boiler and Pressure Vessel Code provides rules for the construction of pressure vessels having an internal or external pressure that exceeds 15 psi, and the largest cross sectional dimension exceeds 6 inches.
Included within the scope of this Code are: unfired steam boilers, evaporators or heat exchangers, vessels in which steam is generated from process steam heat, direct fired vessels not within the scope of other parts of the Code, and gas fired jacketed steam kettles.
Excluded from the scope of this Code are: pressure vessels within the scope of other Sections, fired process tubular heaters, pressure containers that are integral parts of rotating or reciprocating mechanical devices, piping systems, piping components, vessels for containing water under pressure (not exceeding 300 psi or 210° F), and water supply storage tank (heated by indirect means and heat input limited to 200,000 Btu/hr, water temperature limited to 210° F, and water capacity does not exceed 120 gallons).

Alternative Regeln für Druckbehälter
Section VIII, Division 2 provides rules for the construction of stationary pressure vessels and vessels installed in oceangoing ships, barges, etc. This division provides rules for the construction of pressure vessels having an internal or external pressure that exceeds 15 psi, and the largest cross sectional dimension exceeds six inches. Vessels that may be manufactured per Section VIII, Division 1 may also be manufactured to the requirements of this Division unless specifically prohibited.
Excluded from the scope of this Code are: pressure vessels within the scope of other Sections, fired process tubular heaters, pressure containers that are integral parts of rotating or reciprocating mechanical devices, piping systems, piping components, vessels having a capacity of 120 gallons or less for containing water under pressure, and water supply storage tank (heated by indirect means with heat input limited to 200,000 Btu/hr, water temperature limited to 210ÙF, and water capacity limited to 120 gallons).

Hochdruckbehälter
Section VIII, Division 3 of the ASME Boiler and Pressure Vessel Code provides rules for the construction of stationary pressure vessels that are normally designed for pressures above 10.000 psi. In addition, vessels may be moved from location to location when not pressurized.
Direct fired vessels not within the Scope of Section I may be manufactured to this Division.
Excluded from the scope of this Code are: pressure vessels within the scope of other Sections, fired process tubular heaters, pressure containers that are integral parts of rotating or reciprocating mechanical devices, and piping systems.

Section X

Druckbehälter aus faserverstärktem Kunststoff
Section X of the ASME Boiler and Pressure Vessel Code provides rules for the fabrication of fiber-reinforced thermosetting plastic pressure vessels. This Section defines two classes of design: Class I and Class II. Class I vessels are qualified by the destructive testing of a prototype vessel. Class II vessels are qualified by mandatory design rules and nondestructive testing.
Class I vessels are limited to 150 psi when fabricated by bag-molded, centrifugally cast, or contact molded methods. For filament-wound Class I vessels, the maximum permissible pressure is 1500 psi and for filament-wound vessels with polar boss openings, the maximum permissible pressure is 3000 psi.
Class II vessels are designed by one of two methods: Method A - Design Rules or Method B- Discontinuity Analysis.
The design temperatures are limited to the lower of 250° F or 35° F below the maximum use temperature of the resin. The minimum design temperature is -65° F.
Section X vessels shall not be used for lethal service.
