Forgings made from ASTM A105 or ASME SA-105 materials, either forged flange or forged fittings, can be applied to the ASME Boiler and Pressure Vessel Codes (BPVC). The ASTM A105/ ASME SA-105 carbon steel forgings are designated with an UNS number K03504. It has a P-number of 1 and Group number of 2. It has an accurate equivalent ASME SA-181 …

What’s the flange facing finish? The facing finish or face finish of a pipe flange manufactured in accordance with ASME B16.5 refers to the smoothness or roughness of the facing surface. In a bolted flange joint, the flange face is in direct contact with the gasket. As the bolting is tightened, the softer gasket material flows into the minor machining …

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 …

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 …

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 …
