The machining and manufacturing precision of the threaded opening of the pipeline directly influences the installation precision of the pipeline and the sealing degree of the pipeline, and even influences the handover operation of the whole set of tool; the processing and manufacturing speed of the pipeline threaded port directly influences the construction period.

The threading method of the traditional pipeline threaded opening comprises the following steps: for a pipeline with a larger caliber, placing the pipeline on the ground, using a batten to pad the pipeline, using a pipe wrench to fix the threading end part of the pipeline, and then installing a threading device for processing; for the pipeline with a smaller caliber, the threading end part of the pipeline is manually lifted and fixed by a pipe wrench, then a threading device is installed for processing, and after the processing is finished, the pipe wrench is loosened and the threading device is removed.

The disadvantages of the above method are:

1) the floor is inconvenient to construct and operate, the qualification rate is influenced, and the phenomenon of rework is easy to generate;

2) the pipeline is fixed by pipe tongs, and the labor cost is wasted because of the assistance of personnel with large strength;

3) the pipe tongs are fixed, the pipe tongs need to be purchased, the specification is more, and the tool cost is higher;

4) the pipe wrench is used for fixing manually, the fixing is not firm, the screw thread is not uniform and poor in forming due to the fact that displacement is easy to generate during threading, material waste and rework phenomena are easy to generate, and pipelines can be scrapped when the phenomenon is serious.

5) The threading method needs high personnel matching degree, easily generates injury accidents caused by improper personnel matching and has potential safety hazards in operation.
