A double-tapped bushing, commonly shortened to bushing, is a fitting which serves as a reducer. It is a sleeve similar to a close nipple, but is threaded on both its inner and outer circumferences. Like a reducer, a double-tapped bushing has two threads of different sizes.
A coupling whose ends use the same connection method but are of different sizes is called a reducing coupling or reducer. An example is a 3/4" NPT to 1/2" NPT coupling. An example is a 3/4" NPT to 1/2" NPT coupling.
They are used where the diameter of the pipe on the upstream side of the fitting (i.e. where flow is coming from) is larger than the downstream side, and where there is a danger that vapour may accumulate. [1] Unlike a concentric reducer, which resembles a cone, eccentric reducers have an edge that is parallel to the connecting pipe, referred ...
Nipple. In plumbing and piping, a nipple is a fitting, consisting of a short piece of pipe, usually provided with a male pipe thread at each end, for connecting two other fittings.
Bushing (bearing), a type of plain bearing; Bushing (electrical), an insulated device that allows a conductor to pass through a grounded conducting barrier; Bushing (isolator), a mechanical device used to reduce vibrational energy transfer between two parts; Drill bushing, a tool used to guide the placement of a hole when drilling in a workpiece
Simple diagram of a drilling rig and its basic operation. The kelly drive is #19. A kelly drive is a type of well drilling device on an oil or gas drilling rig that employs a section of pipe with a polygonal (three-, four-, six-, or eight-sided) or splined outer surface, which passes through the matching polygonal or splined kelly (mating) bushing and rotary table.
