ASTM A105 Flanges

ASTM A105 flanges are forged carbon steel flanges for ambient- and higher-temperature service in pressure systems. These flanges may be manufactured in accordance with a variety of standard specifications covering ASME B16.5, ASME B16.47, ASME B16.48, ASME B16.36, MSS SP 44, API 605, and API 6A, etc. Flanges made to ASTM A105 material are limited a maximum weight of 4540 …

Material Groups of ASME B16.5 Flanges

General Introduction Flanges conforming to ASME B16.5 shall be made from forgings, castings, or plates in a variety of metal grades. These various metal grades can be further categorized into many material groups as listed in tables below according to same pressure-temperature ratings. Besides, these materials shall be applied with the following restrictions: (1) Plate and flat bar materials may …

ASME B18.2.1 Length Tolerances for Bolts

According to ASME B18.2.1, bolt length shall be the distance measured parallel to the axis of the bolt from the bearing surface of the head to the extreme end of the bolt, including the point if the bolt is pointed. The length tolerances for bolts are listed in below tables. Length Tolerances for Nominal Sizes 1/4″ to 3/4″ *All values …

NPS vs DN

NPS is the abbreviation for nominal pipe size while DN is short for nominal diameter. The two designations have simple correlation between each other. *The correlation between NPS and DN. For NPS ≥ 4, the related DN = 25 multiplied by the NPS number.
