ASTM A182 F5 Flanges are used in pressure systems, Included are flanges, fittings, and similar parts to specified dimensions or to dimensional standards, such as the ASME specifications.

ASTM A182 F5 Flanges is a method of connecting pipes, valves, pumps, and other equipment to form a piping system. It also provides easy access for cleaning, inspection or modification. Flanges are usually welded or screwed. Flanged joints are made by bolting together two flanges with a gasket between them to provide a seal. Chromium-Molybdenum Alloy Steel or Chrome-Moly, CrMo is an alloy steel intended for high temperature and high-pressure services. Chrome-Moly is used in the power generation industry and the petro-chemical industry because of its tensile strength, corrosion resistance and high-temperature strength. Chrome-Moly has a better strength to Weight ratio than steel, which enables designers to use thinner wall pipe or smaller diameter tubing to reduce overall weight.
