Cleaning pipes from salt deposits is a complex environmental problem. On the basis of experimental and industrial tests it has been established that electrohyde-ro-pulse technology provides effective removal of salt deposits from the inner surface of pipes and significantly reduces radiation emission from pipes.
Cleaning of tubing from salt deposits, which often have an increased radioactive background, is a complex environmental problem. On the basis of the experimental studies it was found that the most effective is the scheme of electrohydropulse cleaning with a discharge on the pipe wall.
The main share of accidents on oil pipelines, leading to serious negative environmental consequences, is associated with corrosion destruction of pipes. The most difficult task is corrosion protection of the welded joint of the pipes. The use of electric pulse technologies for fixing the elements of anticorrosive protection in butt-end areas of inner surface of pipes allows to increase the corrosion resistance of a pipeline and to decrease the expenses for its installation. The results of the conducted research allowed developing technological processes of fixing aluminum alloy protectors in pipes by means of magnetic-pulse welding, magnetic-pulse and electrohydropulse pressing of thin-walled stainless steel bushings into near-end sections of pipes, as well as creating the necessary equipment for implementing these processes.
