Standard Specification for Gray Iron Castings for Valves, Flanges, and Pipe Fittings
N A126
Annotation
This specification covers three classes of gray iron for castings intended for use as valve pressure retaining parts, pipe fittings, and flanges.
The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
NOTE 1—The text of this standard references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard.
Автоматический перевод:
Стандартная спецификация для отливок серого чугуна для клапанов, гребней и работ водопроводчика
Эта спецификация покрывает три класса серого чугуна для кастингов, предназначенных для использования в качестве стопорных деталей давления клапана, работ водопроводчика и фланцев.
Значения, утвержденные в модулях дюйма-фунта, должны рассматриваться как стандарт. Значения, данные в круглых скобках, являются математическими преобразованиями в единицы СИ, которые обеспечивают только для информации и не считают стандартными.
