Title: Cast-stone sectors for lining bends in pipework

The authors disclose an efficient method for lining the bends of pipelines used to deliver coal dust to the burners of coal-fired power plants or to transport coal slurries in mining and preparation enterprises. The method consists of melting a wear-resistant silicate compound and casting it in the form of rings whose increased width on the outboard side accounts for the angle of the bend when the rings are installed consecutively inside the pipe. Enhanced service life estimations and cost benefit analyses are given for pipe bends thus lined in both of the above applications.
