Abstract: A pipe grooving device includes an assembly adapted to receive an end of the pipe. The assembly includes a cup which surrounds a pipe end stop. The cup and the pipe end stop may be mounted on a fixed pinion about which a carriage rotates. The carriage carries geared cams which engage the pinion and rotate synchronously when the carriage rotates relatively the pinion. The cams engage a pipe element received by the cup and form a circumferential groove in the pipe element. The cup and the pipe end stop move independently of one another axially along a pinion shaft to actuate rotation of the carriage. The cup accommodates dimensional pipe diameter tolerances and mitigates pipe flare and maintains pipe roundness during the grooving process.

Abstract: Bellows are devices used to compensate linear, thermal, or angular movement/expansion. In oil and gas industry bellows are used in gas lift valves as a slidable seal between two gases. Gas lift valves are used in process of oil artificial lift from wells. Bellows having very thin walls are not well suited for pressures higher than approximately 200 PSI. To withstand much higher pressures bellows are being crimped, process that compresses the bellow to shorter length which increases bellow mechanical toughness. This patent application refers to bellow crimping method that uses initially balanced internal and external pressure to crimp bellow to desired length and maintain perfect bellow elements-convolution ? geometry using custom designed crimping device.
