Improving the Method of Replacing the Defective Sections of Main Oil and Gas Pipelines Using Laser Scanning Data

Autor: Ildar Shammazov, Enver Dzhemilev, Dmitry Sidorkin

Publikováno v: Applied Sciences, Vol 13, Iss 1, p 48 (2022)

During the operation of main pipelines, many defects occur in the body of the pipe and on its surface. The main method for eliminating such defects is cutting out the defective section and welding a new one in its place. The cutting process is compli

Research into methods of pipe end demagnetization under main pipeline repair

Autor: P.N. Dobrodeyev

Publikováno v: Electrical engineering & Electromechanics, Iss 3, Pp 50-54 (2014)

Efficiency of pipe end demagnetization methods is experimentally investigated to avoid arc magnetism at repair welding jobs on main pipelines. It is found that multi-polar biased static and dynamic demagnetization provides an acceptable level of magn
