The name Wolframium e was due to the fact that tungsten, accompanying tin ores, interfered with the smelting of tin, converting it to slag foam (the so-called wolf foam). The metal has a light gray color.
I use high-tech processes for the production of raw materials that increase not only the quality and cost of the material, but also the development of the industry as a whole.
The advantage of a tungsten pipe is manifested in the refractoriness of tungsten, its heat resistance and heat resistance. Pipes are resistant to many aggressive environments, including solutions of alkali, sulfuric, hydrochloric and nitric acids. Tungsten products have many distinctive qualities: wear resistance and protection against fatigue during heating and cooling and the lowest coefficient of expansion among metals of this class. Tungsten has a wide range of tension and compression, good resistance to thermal creep and high thermal conductivity. The complex technological process for producing tungsten leads to an increase in the total cost of tungsten products. Moreover, the weight of finished products is very high.
They produce tungsten pipes from billets using high-tech equipment. Using vacuum heat treatment and modern chemical processing technologies. The quality of the material produced is monitored at all stages.
