Slurry Transportation Piping Systems
B31.11 slurry transportation piping systems
The primary use of this code is for aqueous slurries between plants and terminals. It also covers use within those areas. One of the uses of these systems is in the mining industries in moving ores from the mines to elsewhere.
Paragraph 1100.1.2 states the elements to which it does not apply:
- Auxiliary piping such as for water, air, and similar liquids and gases
- Pressure vessels
- Piping designed for pressures below 103 kPa (15 psig) at any temperature
- Piping designed for pressures above 103 kPa (15 psig), when temperature
is below –30°C (–20°F) or above 120°C (250°F)
-Piping within the battery limits of slurry processing plants and other
nonstorage facilities
- Design and fabrication of proprietary items
A careful reading about each of the codes would find many similarities,
especially for the elements to which the piping codes do not apply.
They do not design for under 105 kPa (15 psig). They are for piping, not
pressure vessels and other elements of a project that are covered by the
ASME BPV Code.
