Definition of Piping
Pipe is a pressure tight cylinder used to convey a fluid or to transmit a fluid
pressure, ordinarily designated pipe in applicable material specifications
...
Piping is an assembly of piping components used to convey, distribute, mix,
separate, discharge, meter, control or snub fluid flows
...
Piping components are mechanical elements suitable for joining or assembly
into pressure-tight fluid containing piping systems
...
Piping is typically round
...
2 Piping Nomenclature, Components
Graphic of piping system illustrating
• header
• Branch connection
• Valve
• Flange
• Expansion joint
• Expansion loop
• Pipe support
• Reducer
• Elbow
Pipe system essentials:
Take off
• Branch run
Stub in
• Branch fitting connection made to
header by direct attachment of
branch
Branch reinforcement
• Material added in the vicinity of a
branch opening to restore the
mechanical integrity of the pipe
NPS
• Nominal pipe size
Pipe support
• Support elements which serve to
maintain the structural integrity of the
piping system, these are typically
non-linear elements
Spring support
• Support provided by an element
composed of a spring assembly,
these are linear support elements
Snubber
• Support provided by an element
composed of a non-linear, damping
element
Category D
• Within reference of B31
...
3, a service
classification
Expansible fluid
• Any vapour or gaseous substance,
any liquid under such pressure and
temperature such that when pressure
is reduced to atmospheric, will
change to a gas
Hydro test
• Test pressure = 1
...
3 Regulatory Acts, Codes & Standards
Codes
Codes are rules for the design of prescribed systems which are given the force
of law through provincial, state and federal legislation
...
Boilers and Pressure Vessels Regulation
• Prescribes requirements for registration of pressure vessels, boilers, pressure
piping and fittings
Design, Construction and Installation of Boilers and Pressure Vessels Regulations
• Cites the codes and “bodies of rules” that form part of the regulations
• CSA B51 Boiler, Pressure Vessel and Pressure Piping Code
• CSA B52 Mechanical Refrigeration Code
• CAN/CSA Z184 Gas Pipeline Systems
• ASME Boiler & Pressure Vessel Code
• ASME B31 Pressure Piping Codes
