feature

Tungsten — the most refractory of metals, is the basis of most high-temperature products. Tungsten pipes have excellent performance: wear resistance, toughness, high temperature resistance, minimum thermal expansion coefficient. All known hardness material with admixture of oxygen and carbon. Tungsten inert in an oxygen atmosphere to 400 °C, hydrogen to 600 °C, ammonia to 700 °C, carbon monoxide to 800 °C, in concentrated solutions of acids, alkalis, Aqua Regia, boiling mercury, It reacts with a mixture of nitric and plasmavol acids, a mixture of hydrogen peroxide and ammonia at t° red heat, with chlorine and hydrogen sulfide at 250 °C, boiling sulfur hot Aqua Regia, nitric acid, melts of salts of alkaline earth metals, bromine, fluorine, iodine.

production

The most popular tungsten tube cross-section 0,2 — 40 mm with a wall thickness of 0.06 — 10 mm. They are manufactured from certified billet obtained by powder metallurgy. Processing is carried out in a vacuum using special equipment. Chemical treatment is made using the latest technology. Quality controlled at all stages of production.

application

Without tungsten refractory tubes it is impossible to imagine nuclear energy, military-industrial complex, modern metallurgy, electrical engineering. Active progress of robotics, petrochemical, process industry also needs refractory tubes. They are designed for operation in aggressive liquid and gaseous environments in conditions of extreme static and dynamic loads under the highest temperatures.
