works are performed without dismantling the flanges and the equipment as a whole (carried out “on site”);
the service life of the apparatus is prolonged due to the restoration of the sealing surface of the flanges;
no need to perform labor-intensive work and subsequent inspection of the welded joint in case of disassembling the flanges for subsequent groove;
minimum working space is required in the area of the treated surface;
reduced overall repair time;
allows you to avoid the occurrence of product passes through the flange connection, and as a result, subsequent unplanned shutdowns of production.
