A NEW PROCESS FOR REPAIRING OF MONO-BODY CYLINDER OF HYDRAULIC PILLAR

Analyzed in the article are the elements responsible for scrapping of the mono-body of cylinder of mine-used hydraulic pillar. The author also describes the process for repairing hydraulic pillar cylinder bodies scrapped with corrosion and the effectiveness thereof. The said process involves the use of lined corrosion-resistant metal tube. At last, it is proposed to spread the application of dual-metalic materials in hydraulic pillar-making industries.
