ASME Flanges Standard

What is a ASME Flanges Standard

The stamp of ASME certification denotes high performance capabilities for engineered components around the world. Tested and certified according to the research and standards of the American Society of Mechanical Engineers, these mechanical assemblies, systems, and structures bear the weight of the toughest jobs and highest expectations.

What is ASME ?

- In addition to providing services as a professional association supporting engineering practice and allied sciences, the American Society of Mechanical Engineers maintains ASME codes and standards for equipment.

- Since its founding in 1880, ASME has grown as a multipurpose organization: it is at once an engineering society, a standard-governing organization, a research and development authority, a lobbying organization, a source of training and education, and an active nonprofit. ASME and its standards are both multidisciplinary and global, with members in 158 countries.

- In addition to standards governing flanges and fittings, ASME’s 600+ codes and guidelines cover: Fasteners, Elevators, Plumbing fixtures, Pipelines, Power systems, Boilers and pressure vessels

- It’s ASME’s goal to not only institute useful standards and regulations for the sake of consistency, but to provide industry best practices that result in operational, safety, and overall cost benefits for users at all levels.

ASME B16.47 Flanges Standard

- One of the most useful standards governing ASME Certified flanges, ASME B16.47 - 2011, applies explicitly to large diameter steel flanges of NPS 26 through NPS 60 metric/inch. It covers standards, evaluations, requirements, and recommendations for characteristics including: Pressure-temperature ratings, Dimensions, Materials, Tolerances, Marking, Testing, Bolting, Gaskets

- These flanges may be crafted of cast, plate, or forged materials in ratings Classes 75, 150, 300, 400, 600, and 900.

- The remainder of the ASME B16 series of standards is also useful for flange applications, as are the B31 piping codes and the B&PVC, or Boiler and Pressure Vessel Code.

ASME Certified Flange Types

With a range of designs, different ASME Certified flanges offer specialized support in covering, closing, and connecting industrial pipe systems. The six most common designs include:

ASME Slip-on Flanges

Which slide on over a pipe with a close fit

ASME Weld Neck Flanges

Which are machined to fit a pipe’s inside diameter and fastened by welding

ASME Blind Flanges

Which seal the ends of pipes and vessel openings

ASME Lap Joint Flanges

Which pair with stub end fittings for easy assembly and disassembly

ASME Threaded Flanges

Which fit threaded pipes for a non-welded finish

ASME Socket-Weld Flanges

Which fit pipes socket-style with a top weld for maximum inner flow
