Study Notes
- Fittings requiring registration include pipe fittings, expansion joints, hose assemblies, measuring devices, and pressure relief devices.
- Registration material (including CRN) must be provided by the supplier for every registered fitting installed or replaced.
- Jurisdictions prohibit the use of non-registered fittings in pressure service.
- Fittings must be clearly marked with manufacturer name, service designation, and material designation for safe and proper use.
- Power Engineers must consult the correct ASME codes (BPVC I for high-pressure plant piping, and B31.1, BPVC IV, and B31.9 for low-pressure plant piping) when designing, repairing, or installing piping systems.
- Boiler piping is divided into three categories: boiler proper piping, boiler external piping, and nonboiler external piping.
- Existing piping systems and new installations must follow the correct code for safe and durable piping systems.
- ASME BPVC I has administrative jurisdiction over boiler external piping, but ASME B31.1 has technical jurisdiction, including rules for steam piping, feedwater piping, blowoff piping, and blowdown piping.
- Proper identification, installation, and testing of fittings and piping systems are essential for safety and performance.
- Improperly identified fittings or piping must never be placed in pressure service.
- Fittings must be made of suitable materials and be of proper strength for the specific application to avoid failure or incompatibility.
