Piping Specifi cations
For piping, the basic considerations are: the design temperature, the pressure
retained by the pipe, the fl uid in the pipe, the load resulting from thermal
expansion or contraction, impact or shock loads imparted such as water hammer,
external loads, wind loads and vibration from equipment.
Adhere to the following for piping installation (see Figure 7):
1. Ensure the arrangement of the piping and its appurtenances takes into
consideration the location of other structures and equipment adjacent to
the piping, which may result in freezing interference and/or damage as a
result of expansion, contraction, vibration, or other movements.
2. Consider the appropriate location and orientation of valves necessary
for safe operation and isolation of the piping. Valves are used in piping
systems to stop and start the fl ow of fl uids, to regulate fl ow, to prevent the
back fl ow, and to relieve excessive pressure build up in the piping.
3. Ensure all piping and piping components are suitable for the design
temperatures, pressure and fl uid used in the system.
4. Ensure all components exposed to thermal fl uid fl ow, including pipe,
valves, and screens, are not copper, copper alloys, bronze, brass,
aluminum, or cast iron. Cast iron is porous to thermal fl uids, and copper
and aluminum act as catalysts in the degradation of some thermal fl uids.
Carbon or stainless steel, or ductile iron, are recommended.
5. Ensure all pipework is constructed from seamless mild steel pipe,
conforming to ASME SA 106B or SA 53B, Schedule 40, Schedule 80, or
equal, based on design temperature and pressure of the system.
6. If an isolating valve is completely closed, the pressure in the system will
rise to the deadhead pressure of the pump. Suitably sized pipe will enable
the system to withstand the total head generated by the circulating
pump, should this occur. In applications where it is desirable to design
to pressures lower than 100 psig, an alternative safeguard is to install
appropriately sized safety valves.
7. Where secondary circulating pumps are installed, ensure the system is
