| Summary: | Заглавие с экрана The manufacturing methods of preparations for piston rings of high-pressure compressors for production of polyethylene is adduced. Preparations are obtained from multialloy lead-tin bronze by a method of centrifugal casting. It is offered to use licensed protective-separating coating and prewarming of a foundry core that allows to lower a scrap rate considerably at their moulding. Commercial tests of rings executed of these preparations have shown, that their durability exceeds russian and insignificantly concedes to foreign analogs.
