ASME - What does it stand for and what do they cover?

American Society of Mechanical Engineers

-Nonprofit for engineering disciplines including pipe trades

• Founded 1880

-2 most common sections:

-ASME B31 (aka piping code)

-ASME Boiler and Pressure Vessel code. Terminates at the first weld, flange, or threaded joint off the boiler.

ANSI - What does it stand for and what do they cover?

American National Standards Institute

• Founded 1918

• Ensures US standards are applied to international standards.

• Minimum design requirements are accepted as a standard for all piping outside jurisdiction of other codes.

• Piping trades commonly use these:

  • B31.1 Power Piping

  • B31.2 Fuel Gas Piping

  • B31.3 Process Piping - Chemical Plant and Petroleum Piping

  • B31.4 Liquid Petroleum and Transportation Piping

  • B31.5 Refrigeration Piping

  • B31.8 Gas Transmission and Distribution Piping

  • B31.9 Building Service Piping

  • B31.11 Slurry Piping

ASTM - What does it stand for and what do they cover?

American Society for Testing and Materials

• Founded 1898

• Standards for characteristics and performance of materials, products, suppliers, and services.

• 66 volumes divided in 16 sections.

• All accepted piping must be tested with ASTM spec number and grade.

  • ASME accepted pressure retaining materials identified with “S” preceding the “A” which is by ASTM.

    • Ex: A-36 is ASTM, SA-36 is ASME endorsed.

ABSA - What does it stand for and what do they cover?

Alberta Boilers Safety Association

• accepts the national board of boilers and pressure vessel inspectors

• standard of qualifications and exams for inspectors who enforce the code in Alberta

• One uniform code and stamp on all registered pressure vessels

• Pressure piping registration system:

• PP - pressure piping

  • set of numbers - owner of facility

  • letters - inspection district

  • second set of numbers - specific plant of facility

  • letter - type of plant

CSA - What does it stand for and what do they cover?

Canadian Standards Association

• Founded 1919

• Products/materials, building systems for designers, builders, mfg, suppliers, distributors.

• Applications, Design, Energy section, mechanical/industrial section

• CRN - Boilers and pressure vessels installed in Canada require a CRN

• When first registered, CRN is issued in the province where it was first registered with a decimal point to represent the province. Ex: if the desitgn is 823, it would be 832.2 if Nova Scotia.

NRC - What does it stand for and what do they cover?

National Research Council Canada

• brings canadian products, tech, innovations to market.

NPC - What does it stand for and what do they cover?

National Plumbing Code of Canada

• install and design of new plumbing installs
