ASTM A105/A105N

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 kg.

ASTM A105 and A105N steel flanges are not same, they have same raw materials, same steel grades, but different heat treatment requirement. N means Normalization heat treatment, and A105 flange haves no heat treatment requirement. In summary, the ASTM A105 flange and ASTM A105N flange have a same chemical composition, but the A105N have a better mechanical property and usually used in critical situation.

Flange Type:Blind Flange

Blind flanges manufactured in accordance with ASME B16.5 can be provided in Class 150 through Class 2500. It is basically a circular disc that does not have a hub or bored center. Bolts holes are drilled and aligned symmetrically along the circumferential edge of the solid disc. Generally the blind flange may be furnished with raised face (RF), ring join face (RJ), or flat face (FF). The blind flange serves a function similar to that of a plug or cap and is used to blank off the end of piping, valves and pressure vessel openings. It may be fabricated from cast, forgings, specific plates, or flat bars.

Face Type: Raised Face (RF)

The Raised Face flange is the most common type used in process plant applications, and is easily to identify. It is referred to as a raised face because the gasket surfaces are raised above the bolting circle face. This face type allows the use of a wide combination of gasket designs, including flat ring sheet types and metallic composites such as spiral wound and double jacketed types.

The purpose of a RF flange is to concentrate more pressure on a smaller gasket area and thereby increase the pressure containment capability of the joint. Diameter and height are in ASME B16.5 defined, by pressure class and diameter. Pressure rating of the flange determines the height of the raised face.
