Tungsten tube

Advantages of tungsten tubes

The use of knowledge-intensive technologies and alternative raw materials increases not only the competitiveness of the industry, but also its survival in general. This applies directly to the production and use of TTM tubes made of refractory metals. They are based on alloys of molybdenum, tungsten, tantalum, niobium, and chromium. Tungsten, as the most refractory of them, is used for the most heat-resistant products. Tungsten pipes are resistant to aggressive environments of concentrated acids and alkalis. Such tubes have excellent wear resistance, hardness even at high temperature and minimum thermal expansion coefficient, very high compressive and tensile modulus, highest resistance to thermal creep, good thermal conductivity. The durability of such pipes is due primarily to the strength of the material, and chemical inertness.

Disadvantages

Tungsten is a rare element in the earth's crust. Difficulties of its mining and processing by virtue of its unique properties - affect the cost. At standard temperature, it is not a hard and sufficiently ductile metal. In addition, tungsten tubes are very heavy.

Production

Certified billets are processed on high-precision special equipment. Vacuum heat treatment technologies, chemical means of finishing of finished pipes are used. The quality is controlled at all stages. Standard assortment of pipes: Ø 0,15 - 35 mm, wall thickness 0,05 - 10 mm.

Usage

Rapid development of instrumentation, robotics, electronics, automotive, chemical and petrochemical industries stimulate the demand for pipes made of refractory metals. Thus the demand for tungsten and molybdenum pipes from companies alone is more than a ton a year. The list of refractory metals headed by tungsten is indispensable for heat-resistant parts and units that are used in aggressive gas and liquid media. The need for tungsten tubes in nuclear power, aerospace, mechanical engineering, defense industry, electrical engineering, and pharmaceuticals is growing rapidly.
