Free Draining vs No Pockets

Is a line specified as "free draining" the same as one specified as "no pockets"?

RE: Free Draining vs No Pockets

Free draining would imply (to me) that there be no pockets and additionally no valves or other possible blockage.

RE: Free Draining vs No Pockets

Pockets must be able to be drained, either manually or other. What is the application? Pharma has other conotations or requirements to say chemical.

RE: Free Draining vs No Pockets

Free draining means that the line can totally drain in either  or both directions to empty the line.  No pockets means that there should be no liquid traps.  The resulting piping configuration described by these two notes will often be the same.
