Liquid Process Piping


Quiz Questions

1. The design analysis includes the design of the process piping systems. The design criterion includes applicable codes and standards, environmental requirements, and other parameters which may constrain the work.
True
False
2. Isometric drawings include layout piping drawings, fabrication or detail drawings, equipment schedules, and pipe support drawings.
True
False
3. ___________________________ also tabulate process design values for different operating modes, typically normal, maximum and minimum.
Process Flow Diagrams
Piping Flow Diagrams
4. Pre-design surveys are recommended for the design of liquid process piping for new treatment processes and are a necessity for renovation or expansion of existing processes.
True
False
5. Piping and Instrumentation diagram ( P&ID) is represented in
Figure 2-1
Figure 2-2
6. ________________ conditions play a major role in the selection of piping systems.
Weather
Soil
7. Occasional loads are those loads that do not vary considerably over time and are constantly acting on the system.
True
False
8. Wind load is a transient, live load (or dynamic load) applied to piping systems exposed to the effects of the wind.
True
False
9. The toughness of a material is dependent upon both strength and ductility.
True
False
10. The sizing for any piping system consists of two basic components fluid flow design and pressure integrity design.
True
False
11. The Chezy-Manning equation is empirically derived and is limited to use with fluids that have a kinematic viscosity of approximately 1.12 x 10-6 m2/s (1.22 x 10-5 ft /s), which corresponds to water at 15.6EC (60EF), and for turbulent flow.
True
False
12. Fatigue resistance is the ability to resist crack initiation and expansion under repeated cyclic loading.
True
False
13. The selection of support types is dependent upon four criteria: the temperature rating of the system, the mechanism by which the pipe attaches to the support, protective saddles that may be included with the support and the attachment of the support to the building or other structures.
True
False
14. ______________________ can occur when two electrochemically-dissimilar metals or alloys are metallically connected and exposed to a corrosive environment.
Galvanic corrosion
Pitting corrosion
15. Like other plastic materials, thermoset piping systems provide both internal and external corrosion resistance.
True
False
