Tips on using this forum..

(1) Explain your problem, don't simply post "This isn't working". What were you doing when you faced the problem? What have you tried to resolve - did you look for a solution using "Search" ? Has it happened just once or several times?

(2) It's also good to get feedback when a solution is found, return to the original post to explain how it was resolved so that more people can also use the results.

direct quote from a Client's Piping Specification

"The inside diameter of the pipe should be less than the outside diameter to prevent the hole being on the outside",

Don't get me started on their definition and identification of a "long pipe"

Hello Peter,

It's actually the opposite! The inside diameter of the pipe should be larger than the outside diameter to ensure the hole or opening is on the inside. This is because the inside diameter refers to the diameter of the inner opening of the pipe, while the outside diameter is the diameter across the widest part of the pipe, including its walls. Having the inside diameter larger ensures that any opening or hole is contained within the pipe, not on its outer surface.

Hope it would help ypu.
