Chemical Engineering Interview Question:

Are there any general rules that should be considered when designing a slurry piping system?

Submitted by: Administrator

The following are items to consider when designing a piping system that will transport slurries:

1) Whenever possible, piping should be designed to be self-draining

2) Manual draining should be installed to drain sections of the piping when self-draining is not possible

3) Blow-out or rod-out connections should be provided to clear lines in places where plugging is likely or could occur

4) Access flanges should be provided at T-connections

5) Manifolds should have flanged rather than capped connections to allow for easy access

6) Clean-out connections should be provided on BOTH sides of main line valves so that flushing can take place in either direction

7) Break flanges should be provided every 20 feet of horizontal pipe or after every two changes in direction
