ASME

Founded in 1880 as the American Society of Mechanical Engineers, ASME is now a professional organisation with 120.000 members in 151 countries, focussed on Technology, Education, Training and Research in Engineering and the technological community.

ASME runs one of the largest technical publishing houses in the world, organises many technical conferences globally and offers professional training courses.

ASME develops internationally recognised codes and standards that improve safety.

Subject areas:

The ASME Codes

The ASME Codes document and give specific requirements for materials, construction, pressure capacity, leak rate, inspection and tests in different areas such as flange fittings (ASME B16.5), valves (ASME B16.20), process piping (ASME B31.3), power piping (ASME B31.1), steel piping (ASME B36.10).

ASME in figures

ASME Flanges / ASME B16.5

ASME B16.5 describes the requirements for flanges, coils, connectors and fittings for use in pressure lines and other systems that connect different devices. Furthermore the ASME B16.5 standard defines the materials to be used to flanges, coils, connectors and fittings, including alloys, carbon steels and stainless steels. ASME B16.5 regulates together with its dimensions and tolerances the dimensional profile for flanges, coils, connectors and fittings. Furthermore it describes the requirements of pressure capacity and leak rate for flanges, coils, connectors and fittings.

ASME B16.20

ASME B16.20 contains requirements for expansion joints and fittings that are used in pressure line and other systems. ASME B16.20 defines the requirements for materials that should be used for expansions joints and fittings, including alloys, carbon steels and stainless steels. Furthermore it defines the dimensional profile, and their sizes and tolerances, of connectors and fittings. Also defined in ASME B16.20 are the requirements of pressure capacity and leak rate for expansion joints and fittings.

ASME B31.3

ASME B31.3 describes the requirements for process piping, particularly in the context of the petrochemical and chemical industries. ASME B31.3 includes the requirements for materials, that should be used for process piping, including carbon steels, stainless steels, alloys and non-ferrous metals.

Furthermore ASME B31.3 defines the construction and manufacturing requirements for process piping, including the choice of suitable structural shape, of suitable welding processes and of the monitoring of welding works. Also it contains the requirements for pressure capacity and leak rate for process piping.

ASME B31.3 describes requirements on inspections and testing for process pipiing, together with the supervision of materials testing, pressure testing and final inspection.

ASME B31.1

ASME B31.1 describes the requirements for piping in power stations, including steam and condensation systems, heat transport and cooling systems, oil and gas piping systems. Additionally ASME B31.1 sets the standard for materials, including carbon steels, stainless steels, alloys and non-ferrous metals, that should be used for piping in power stations.

Alongside the construction and manufacturing requirements for piping in power stations, ASME B31.1 also defines the choice of suitable structural shape, of suitable welding processes and of the monitoring of welding works.

ASME B31.1 also standardises the pressure capacity and leak rate for piping in power stations. It also defines requirements to be adhered to for inspection and testing of piping in power stations, as well as the monitoring of materials testing, pressure testing and final inspection.

ASME B36.10

The standard ASME B36.10 describes requirements for steel pipelines, which are used in the petrochemical and chemical industries.

The ASME B36.10 standardises requirements for materials, which should be used for steel pipelines, including carbon steels, stainless steels and alloys. Additionally it defines the construction and manufacturing criteria for steel pipelines. This includes the choice of suitable structural shape, of suitable welding processes and of the monitoring of welding works. In this context ASME B36.10 also describes the exact requirements on pressure capacity and leak rates for steel pipelines.

ASME B36.10 also sets out the requirements for inspections and testing of steel pipelines. This also covers the monitoring of materials testing, pressure testing and final inspection.

ASME Section VIII

ASME Section VIII is an important part of the American Society of Mechanical Engineers Boiler and Pressure Vessel Code (ASME BPVC). This chapter of section 8 gives rules for the construction of pressure vessels. Key here are especially the requirements for the construction, manufacture, testing and monitoring of pressure vessels. Section VIII also describes the tolerances to be respected in the construction and use of pressure vessels, as well as the requirements on manufacture inspection and monitoring.

Pressure vessels are used for a large number of industrial purposes, including in the energy, oil and gas industries, in the chemical and petrochemical industries, and in other industrial processes.

Please note:ASME Section VIII is is an important reference for everyone who works in the construction, manufacture, testing and monitoring of pressure vessels, in order to ensure a safe and reliable operation.

Products

The ASME Digital Collection is an online platform, provided by the American Society of Mechanical Engineers. It’s a comprehensive collection of technical resources for mechanical engineering, and contains journals, conference proceedings, standards and books. The platform offers engineers, researchers and students a simple access to a broad range of technical content that is relevant for their technical work. The contents are searchable and can be filtered to reach the desired information. With the ASME Digital Collection users can also access older editions of journals and conference proceedings and stay up to date with the newest research and trends. The ASME Digital Collection is a valuable resource for everyone working in mechanical engineering or in engineering more broadly, and who require access to a broad range of technical content to support their research.

The ASME Standards Collection combines all the ASME Codes and Standards, including the renowned ASME Boiler & Pressure Vessel Code.
