ASME B16. 5 standard covers Steel Pipe Flanges and Flanged Fittings from NPS 1/2 through NPS 24 Metric/Inch in pressure class 150 to class 2500. It covers pressure-temperature ratings, materials, dimensions, tolerances, marking, testing, and methods of designating openings for pipe flanges and flanged fittings.
What is the difference between ASME and ANSI flanges?
ANSI Flanges are manufactured based on standards developed by organizations and ASME Flanges are based on codes and standards for mechanical devices. The ANSI Flanges are designed based on approx. 9500 standards whereas ASME Flanges manufactured on 600 codes and standards for different mechanical devices.
What does ASME B16 20 mean?
As specified by the ASME (American Society of Mechanical Engineers), standard B16. 20 refers to “Metallic Gaskets for Pipe Flanges—Ring Joint, Spiral-Wound, and Jacketed.” In the organization’s own words, ASME B16. 20: “offers comprehensive solutions applying to materials, dimensions, tolerances and marking.

How do you determine flange pressure rating?
ANSI FLANGE PRESSURE RATING EXPLAINED Pressure rating is defined as the maximum allowed pressure that a flange can withstand at increasing temperatures. According to the ANSI/ASME B16. 5 specification, there are seven flange pressure ratings: 150, 300, 400, 600, 900, 1500, and 2500.
What is the difference between ASME B16 5 and ANSI B16 5?
The term “B16. 5” or “B16 5” is used interchangeability and refers to same standard. However, the standard ASME B16 5 (ANSI B16 5) only covers size up to 24 inches. For bigger sizes, ASME B16.
What is the difference between ASME and ISO?
The main differences between the ISO and ASME Drawing Standard in Fusion 360 are as follows: ISO uses A series paper sizes. ASME uses ANSI standard paper sizes.
What is the full form of ASME?
Founded in 1880 as the American Society of Mechanical Engineers, ASME is a not-for-profit professional organization that enables collaboration, knowledge sharing and skill development across all engineering disciplines, while promoting the vital role of the engineer in society.
What is CGI gasket?
The CGI spiral wound is the new standard spiral wound gasket per ASME B16. 20 and is required unless otherwise specified by the user. The CGI is a CG style spiral wound fitted with an internal ring which gives an additional compression limiting stop and prevents inward buckling ring.
What B16 10?

What does ASME B16 9 mean?
The ASME/ANSI B16. 9 specification covers the dimensions and the tolerances of carbon and alloy butt weld fittings. 9 to cover stainless steel and nickel alloy pipe fittings.
What B16 25?
ANSI/ASME B16. 25 is the standard covers the preparation of butt welding ends of piping components to be joined into a piping system by welding. The standard includes the butt welding ends information of General scope, Welding Bevel designs, Preparation of inside diameter of welding ends and the tolerances involved.
What B16 11?
ASME B16. 11 is the standard for the forged steel fittings, including socket weld and threaded type. Material including carbon steel, alloy steel and stainless steel. Also described as Class 2000, 3000, 6000 threaded end fittings and Class 3000, 6000, and 9000 for socket weld end fittings.
What is ASME Class 150 pressure rating?
As temperature increases, the pressure rating of the flange decreases. For example, a Class 150 flange is rated to approximately 270 PSIG at ambient conditions, 180 PSIG at approximately 400°F, 150 PSIG at approximately 600°F, and 75 PSIG at approximately 800°F.
What is the difference between PN16 and class 150 flange?
Steel pipe flanges are classified as per ASME B16. 5 standard. The term “lb”, “class” and “#” are used interchangeably to designate the pressure rating of the flange. The fact is that 150 lb has no relation to 150 psi and so does the 300 or 600 lb does not correlate to 300 or 600 psi pressure rating.
How much pressure can a 600 flange hold?
Flange with 600# rating meets the requirement. You can see that Class 600# can withstand 1205 Psig pressure at 500 °F.
What is difference between ASTM and ASME?
ASTM represents quality for materials to be used in products which are described in ASME. ASTM International is one of the largest voluntary standards developing organizations in the world. ASME standards represents the dimensions and tolerances with respect to each material class.
What is the latest ASME standard?

Is ASTM the same as ANSI?
The OSHA incorporates standards produced by an independent nonprofit organization called ASTM International, or simply ASTM. The OSHA used to include standards produced by the American National Standards Institute, or ANSI, but these were replaced by the ASTM for protective footwear standards in 2005.
What is the ISO standard for GD&T?
ISO 1101 is a 145-page document that contains the GPS drawing symbols and rules for their use. ISO 2768 covers general geometrical tolerance standards for linear and angular dimensions and features that have no tolerance listed on the drawing. ISO 2768 was created in two parts.
What is ISO standard?
ISO 128 is an international standard (ISO), about the general principles of presentation in technical drawings, specifically the graphical representation of objects on technical drawings.
What are ISO standards?
ISO (International Organization for Standardization) is an independent, non-governmental, international organization that develops standards to ensure the quality, safety, and efficiency of products, services, and systems.
What is ASME code welding?
The ASME code requires that welders are certified to specific weld procedures used to fabricate the ASME code vessel. Welder certifications must be documented and maintained. A weld map must be generated that shows which welder performed each weld on an ASME code vessel.
Who founded ASME?
ASME has over 110,000 members in more than 150 countries worldwide. ASME was founded in 1880 by Alexander Lyman Holley, Henry Rossiter Worthington, John Edison Sweet and Matthias N. Forney in response to numerous steam boiler pressure vessel failures.
How many ASME standards are there?
ASME’s standards portfolio includes over 500 standards and associated products. These products cover a breadth of topics, including pressure technology, nuclear plants, elevators / escalators, construction, engineering design, standardization, and performance testing.
