Basic Introduction to ASME B16.5 Flanges

What are ASME B16.5 flanges

ASME B16.5 is the standard specification for pipe flanges and flanged fittings from NPS 1/2 (1/2″) through NPS 24 (24″) covering materials, pressure-temperature ratings, dimensions, tolerances, marking & packaging, and testing methods. ASME B16.5 flanges are designated into seven pressure ratings including Class 150, 300, 400, 600, 900 and 1500 in sizes NPS 1/2 (1/2″) through NPS 24 (24″) and Class 2500 in sizes NPS 1/2 (1/2″) through NPS (12″). The pipe flanges can also be categorized according to its type as: welding neck (WN), slip on (SO), socket welding (SW), threaded (TH), blind (BL), long weld neck (LWN), and lapped joint (LJ). NPS, followed by a dimensionless number, is the designation for nominal flange size. It is related to the reference nominal diameter, DN, which is used in international standards. Their relationship is shown in following table:

Material selection for ASME B16.5 flanges

The pipe flanges can be made from either cast or forged materials. Especially, plate material are only allowed for some certain unhubbed flanges such as blind, slip on plate or reducing plate flanges due to the consideration of plate-lamination flaws. HBMetals manufactures pipe flanges from a comprehensive range of materials covering carbon steel, alloy steel, stainless steel and special alloys:

ASTM A105 flanges

1. ASTM A105 forged carbon steel flanges.

ASTM A105 is the standard specification for carbon steel forgings for piping applications including flanges, fittings and valve parts, etc. According to ASME B16.5(Pipe Flange), this material is categorized into Group 1.1 which has the same pressure-temperature ratings as ASTM A216 Grade WCB, A515 Grade 70, A350 Grade LF2, A516 Grade 70, A350 Grade LF6 Class 1, A537 Class 1 and A350 Grade LF3. ASTM A105 flanges refer to forged carbon steel flanges for ambient and high temperature service in pressure systems.They can be manufactured to dimensional standards of ASME B16.5, ASME B16.47, MSS SP 44, API 605, BS 4504, EN1092-1 and L-005, etc. HBMetals keeps a large amount of flanges available in stock covering flange types of welding neck, slip on, socket welding, threaded, blind, slip on plate, long weld neck, orifice and lap joint, etc.

Pressure-Temperature Ratings For Inconel 600 Flanges

Inconel 600 flanges are forged flanges made from Inconel 600 forgings in accordance with ASTM B564. Inconel 600 is a nickel-chromium-iron alloy which has a nominal designation 72Ni-15Cr-8Fe as well as UNS N06600. These flanges(also called “Alloy 600 flanges”) are widely used in oil & gas projects and chemical processing industry due to its excellent resistance to oxidation at high temperatures and resistance to cracking corrosion and caustic corrosion. ASME B16.5 stipulates the pressure-temperature ratings for Inconel 600 flanges which should be furnished in the heat-treatment condition of anneal.
