Russian Pipe Metallurgical Company TMK has improved the technology for the production of large-diameter pipes at the site of the Chelyabinsk Pipe Rolling Plant. The initiative was implemented as part of a program to improve operational efficiency, its economic effect will be more than 3 million rubles annually.In electric pipe welding shop No 6, located at ChTPZ, the design of a small welding mill was modernized in order to more efficiently use the auxiliary material - ceramic flux, which is used in pipe welding. During the welding process, some of the flux remains unused and is collected by suction nozzles for reuse. Previously, the flux was not collected from the entire surface of the pipe due to the nature of the equipment. By enlarging the guide rods and installing an additional pair of support rollers, the nozzles run along the entire length of the product, which allows you to collect all the unused ceramic flux for further recycling.
