ASTM International (American Society for Testing and Materials International) is an international standards organization that develops and publishes voluntary consensus technical standards for a wide range of materials, products, systems, and services.

Some 12,575 ASTM voluntary consensus standards operate globally.

The organization's headquarters is in West Conshohocken, Pennsylvania, about northwest of Philadelphia.

The American Society of Mechanical Engineers (ASME) is a professional association that, in its own words, "promotes the art, science, and practice of multidisciplinary engineering and allied sciences around the globe" via "continuing education, training and professional development, codes and standards, research, conferences and publications, government relations, and other forms of outreach." ASME is thus an engineering society, a standards organization, a research and development organization, a lobbying organization, a provider of training and education, and a nonprofit organization.

Founded as an engineering society focused on mechanical engineering in North America, ASME is today multidisciplinary and global.

Within industry, piping is a system of pipes used to convey fluids (liquids and gases) from one location to another.

The engineering discipline of piping design studies the efficient transport of fluid.

A pipe is a tubular section or hollow cylinder, usually but not necessarily of circular cross-section, used mainly to convey substances which can flow — liquids and gases (fluids), slurries, powders and masses of small solids.

It can also be used for structural applications; hollow pipe is far stiffer per unit weight than solid members.

A valve is a device that regulates, directs or controls the flow of a fluid (gases, liquids, fluidized solids, or slurries) by opening, closing, or partially obstructing various passageways.

Valves are technically fittings, but are usually discussed as a separate category.

In an open valve, fluid flows in a direction from higher pressure to lower pressure.

The word is derived from the Latin valva, the moving part of a door, in turn from volvere, to turn, roll.
