Boiler Fittings and Registration
- Every valve, piping component, or instrument connected to the pressure side of a boiler becomes pressurized and must meet the required service designation for the boiler to which they are installed.
- Considerations for fitting service include:
- Operating temperature
- Operating pressure
- Material compatibility
- The CSA B51 Boiler, Pressure Vessel, and Pressure Piping Code requires registration of all pressure fittings designed for service at:
- Pressures greater than 103 kPa and temperatures above 65°C
- Pressures greater than 1720 kPa
Registration Process
- The manufacturer of the fitting must have high-quality control standards and proof that the fitting can endure the type of service it was designed for.
- An application for registration is made in the jurisdiction where the fitting will be used.
- Design engineers review the application and evidence, and if the fitting is found suitable, the registering jurisdiction issues a Canadian Registration Number (CRN).
Fittings Requiring Registration
- Pipe fittings (e.g. couplings, tees, elbows, wyes, plugs, unions, pipe caps, reducers, flanges, valves)
- Expansion joints, flexible connections, and hose assemblies
- Strainers, filters, separators, and steam traps
- Measuring devices (e.g. pressure gauges, level gauges, sight glasses, levels, pressure transmitters)
- Pressure relief devices and fusible plugs used for overpressure protection
Importance of Registration
- Installers and end-users are assured of reasonable quality and suitability for pressure service with registered fittings.
- Most jurisdictions prohibit the use of non-registered fittings in pressure service.
Code References
- ASME BPVC I Power Boilers and ASME B31.1 Power Piping Code address design and fabrication requirements for high-pressure plant piping installations.
- ASME BPVC IV Heating Boilers, ASME BPVC VII Recommended Rules for the Care and Operation of Heating Boilers, and ASME B31.9 Building Services Piping Code address design and fabrication requirements for low-pressure plant piping installations.
Piping Categories
- Boiler proper piping
- Boiler external piping
- Nonboiler external piping
ASME BPVC I and ASME B31.1
- Divide high-pressure plant piping into three categories: boiler proper piping, boiler external piping, and nonboiler external piping.
- ASME BPVC I has administrative jurisdiction over boiler external piping, while ASME B31.1 has technical jurisdiction.
ASME BPVC I and ASME B31.1 Code Sections
- Part 122.1: Boiler External Piping
- Part 122.2: Blowoff and Blowdown Piping in Nonboiler External Piping
- Part 122.6: Pressure Relief Piping
- Other important sections of the ASME B31.1 code include:
- Part 122.3: Instrument, Control, and Sampling Piping
- Part 122.5: Pressure-Reducing Valves
- Part 122.11: Steam Trap Piping
- Part 122.13: Pump Discharge Piping
ASME BPVC Boiler Fittings
- Covers materials of construction and installation of many fittings required to ensure the integrity of the boiler proper.
- Includes water columns, water level indicators, pressure gauges, and safety valves.
Power Boilers
- Generate steam or other vapour at a pressure of more than 100 kPa (15 psi).
- Sub-categorized as:
- High-pressure steam boilers
- High-pressure, high-temperature hot water boilers
- Electric boilers
- Miniature boilers
- Organic fluid vaporizers
Heating Boilers
- Generate steam or other vapour at a pressure not exceeding 100 kPa.
- Generate hot water at a pressure not exceeding 1100 kPa or at a temperature not exceeding 120°C.
- ASME BPVC IV rules cover the design and construction of:
- Steam heating boilers
- Hot water heating boilers
- Hot water supply boilers
- Hot water heaters
