The term free point is used to describe the delineating point between the stuck pipe and the free pipe in a pipe string.

Free-point tools are designed to measure torque and stretch in tubing, casings, and drill pipes and to provide accurate free pipe indication.

Each drill pipe comprises a long tubular section with a specified outside diameter (e.g. 3 1/2 inch, 4 inch, 5 inch, 5 1/2 inch, 5 7/8 inch, 6 5/8 inch).

A sewer pipe is normally at neutral air pressure compared to the surrounding atmosphere.When a column of waste water flows through a pipe, it compresses air ahead of it in the system, creating a positive pressure that must be released so it does not push back on the waste stream and downstream traps, slow drainage, and induce potential clogs.
Otorrhea (ear discharge) is the most common complication of tympanostomy tube placement, affecting between 25–75% of children receiving this procedure. [2] [6] [9] [10] Saline washouts and antibiotic drops at the time of surgery are effective measures to reduce rates of otorrhea, which is why antibiotic ear drops are not routinely prescribed.
