ABSTRACT:
A semi-automated plant for threading pipe, including oil and gas well casing and tubing, is disclosed. A particular sequencing of equipment activation and movement is utilized in order to have normal operations of the plant, from loading of unthreaded pipe to the unloading of pipe having threads on each end, and a coupling applied to at least one of the ends, performed without requiring manual handling of the pipe. One particularly important portion of the apparatus in the plant is the lifting device for raising the pipe to the height which is proper for the threading machine, or lathe, and a clamping device for clamping the pipe during the threading operation. By use of the disclosed apparatus, the pipe is accurately raised to the proper height, and pipe over a considerable range of size can be securely clamped during the threading operation.
