Wolfram is a refractory metal, which makes it the basis of heat-resistant and heat-resistant products.
Wolfram pipes are resistant to aggressive media (sulfuric, hydrochloric, nitric acids and others).
Wolfram pipes have excellent mechanical qualities, wear resistance, hardness, have the least expansion with temperature fluctuations, because wolfram has a high modulus of tension and compression and is extremely resistant to temperature creep.
In addition, wolfram pipes have good thermal conductivity.
Tungsten tubes are widely used at high temperatures due to the peculiarities of tungsten, since its melting point reaches 3410 and its density is above 18.2g / cm3. Our company can provide various tungsten tubes characterized by high accuracy, surface cleanliness, direct dimensions and high temperature distortion.
