Improved Design of Machine for Cold Cutting of Oil Pipes and Gas Pipelines

The article describes the methods and equipment for cold cutting of large diameter pipes and shows their main advantages. It presents the design of a new machine for cold cutting of pipes, with independent electromechanical drives. Study was carried out of this design, based on the mathematical model of the drive machinery. The research has obtained dependencies for calculating necessary drive capacities. Results of the study were used to design a test prototype of the new machine. This new design allows to speed up the process of pipe-cutting, eliminates overload-caused tool breakage, enables a remote control of the machine, and makes the operator's work safer.
