【国外标准】 Standard Specification for Non-Reinforced Extruded Tee Connections for Piping Applications

This specification covers the pipe materials and dimensions for producing non-reinforced extruded tee connections manufactured by mechanical forming processes. The term “extruded tee connection” applies to butt-weld or socket-weld connections. The non-reinforced extruded pipe tee connection is an alternative to the tee fittings, nozzle, and other welded connections. The non-reinforced extruded pipe tee connection has been widely used for systems in the marine, process piping, food, pharmaceutical, and similar industries. Different materials that have acceptable forming qualities to produce extruded tee connections shall consist of copper, copper-nickel alloy, titanium, steel, and stainless steel. The extruded tee connection shall be free from burrs and cracks, which would affect the suitability for the intended service.1.1 This specification covers the pipe materials and dimensions for producing non-reinforced extruded tee connections manufactured by mechanical forming processes. The term “extruded tee connection” applies to butt-weld or socket-weld connections. This specification refers to the forming process that leads to welding or brazing.1.2 The non-reinforced extruded pipe tee connection is an alternative to the tee fittings, nozzle, and other welded connections.1.3 The non-reinforced extruded pipe tee connection has been widely used for systems in the marine, process piping, food, pharmaceutical, and similar industries.1.4 The extruded tee connection will be welded in accordance with Specification F722. Brazing of tee connections will be in accordance with ASME B31.5.1.5 The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to inch-pound units that are provided for information only and are not considered standard.1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
