The MTF-K crucible mold is intended for thermite welding of cathodic protection and drainage leads (with a diameter of 3–8 mm) to steel main pipelines made of pipes with diameters from 50 to 1400 mm and a wall thickness of at least 3.5 mm.
The sign is installed at the boundaries of the right-of-way in locations where the pipeline crosses highways, railways, and bodies of water, at overhead pipeline crossings over natural and artificial obstacles (on both sides), and at entry and exit points of the pipeline from compressor station, gas distribution station, and gas metering station sites, at a distance of 50 m from the fencing.
