Subs PKNM
Group of companies developed technology of hardening thread subs by ion vacuum nitriding. The company has used its own method, based on nanotechnology.
Technology "PKNM" allows you to improve the mechanical properties of the equipment, cement the thread, as well as to increase the operational life of subs. When nitriding subs, products undergo thermochemical treatment, during which the metal surface is saturated with nitrogen gas in a special vacuum environment when applying a constant voltage pulse polarity.
, manufactured by "PKNM" used in the course of drilling, maintenance and exploration of the connection between the individual parts of a drill string.
The first samples nitrided subs in six months will be tested in the "RN-Drilling" (Nefteyuganskiy Branch).
"PKNM" — the only company in Russia that use Nanotechnology Thread for hardening subs.
"Many drilling companies are increasingly faced with the need to work in difficult geological and climatic conditions, — said the director of TD" PKNM " Vladimir Zharennikov. — The use of traditional equipment may not be effective because it is subject to extreme wear in such drilling conditions. Nitrided subs differ extended service life due to the use of nanotechnology in the production: in the first phase of testing their subs resource increases to 700 make-ups. "
The group of companies "PKNM" produces products for the oil companies, chemical, nuclear and aviation industries since 1993. A major focus of today is the production of equipment for oil drilling and neftedobychi.V including consumers’ PKNM "oil, drilling and service companies from Russia, Kazakhstan, Uzbekistan, Tajikistan, Azerbaijan, Lithuania and Bulgaria. Partners are NK "Rosneft" Drilling Company "Eurasia" and "Lukoil". In 2009, "PKNM" has applied for funding for innovative developments in JSC "RUSNANO".
