Piping – Manitoba

Last updated May 3 2014 LRB

Information has been gathered from the following sources: Inspection and Technical Services Manitoba website, accessed May 3 2014 C.C.S.M. c. S210 The Steam and Pressure Plants Act July 6 2001, Responsibilities Manitoba Steam and Pressure Plants Act and Regulation Manitoba Power Engineers Act and Regulation, C.C.S.M. c. P95 The Power Engineers Act June 14, 2012, Flow Chart for Installation of Piping Systems,

From these sources it is not possible to create a consistent flowchart to determine whether a piping system needs registration or not. We recommend contacting the government of Manitoba to determine if your piping system needs registration, or if registration is not required but all other Manitoba requirements must be followed, or if your system is exempt from all requirements.

The Steam and Pressure Plants Act

C.C.S.M. c. S210 July 6, 2001, current as of May 1 2014

Definitions:

“plant” means a steam plant or a pressure plant;

“pressure plant” means an installation designed or used for utilizing or confining, under pressure, any liquid or gaseous substances other than steam, and includes the compressor thereof and all appurtenances connected therewith, but does not include (a) those that have a capacity of less than 1 1/2 cubic feet, and (b) those that are operated subject to a pressure less than 15 pounds to the square inch;

“refrigeration plant” means a pressure plant in which refrigerants are vaporized, compressed, and liquefied, in their refrigerating cycle, and includes the complete installation of machinery in connection therewith;

“steam plant” means an installation designed or used for generating, utilizing, confining, or storing, under pressure, steam or hot water, including the boiler thereof and all appurtenances and appliances connected therewith, but does not include (a) those that develop less than three horse power, (b) those that are used for heating a building designed and constructed as a private residence intended to house not more than one family, and (c) those that are used for heating a building used solely for residential purposes and containing not more than two separate apartments or suites;

This act does not provide a definition of piping.

The Power Engineers Act

C.C.S.M. c. P95 June 14, 2012

Definitions:

“plant” means a steam plant, pressure plant or refrigeration plant, or any combination thereof, and all appurtenances and appliances connected therewith;

“pressure plant” means an installation designed or used for utilizing or confining, under pressure, any liquid or gaseous substance other than steam, including the compressor thereof and all appurtenances connected therewith;

“refrigeration plant” means a pressure plant in which refrigerants are vaporized, compressed and liquefied in their refrigerating cycle, including the complete installation of machinery and all appurtenances connected therewith;

“steam plant” means an installation designed or used for generating, utilizing, confining or storing, under pressure, steam or liquid, including the boiler thereof and all appurtenances and appliances connected therewith.

“What Designs Must Be Registered?” The two CSA standards, B51 and B52, contain administrative requirements for registering drawings, specifications and Data Reports with the jurisdictional authority. Manitoba has fully adopted the design registration requirements described by these codes for the following processes: … Registration of design for pressure piping of a volume 17 cubic feet and larger…

“General Requirements for Design and Fabrication of Pressure Piping Systems” All pressure piping systems for use in Manitoba shall be designed and constructed in accordance with the applicable ANSI/ASME Piping Codes and the Manitoba Labour and Immigration, Steam and Pressure Plants Act.

Flow Chart for Installation of Piping Systems

This Flow Chart is found on the Inspection and Technical Services Manitoba website:

Please note that although systems under 17 cuft are exempt from registration, they still have to be fully compliant with all other Manitoba requirements, including Authorized Inspector sign-off on Manitoba forms and the use of registered fittings. The Steam and Pressure Plants act suggests that some pressure piping systems under 15 psi might be exempt from all requirements, but that is not covered in this flowchart. Please contact the Manitoba Government for more details about the requirements of your piping system.
