Relevance
Manufacture and application of pipe made of refractory metals such as tungsten niobium, molybdenum, chrome, tantalum depend on development of high technologies, which increase competitiveness and survivability of industry. Among the most refractory know metal, tungsten is a basis of the most heat-resistant products. Tungsten pipes possess resistance in aggressive environments, concentrated solutions of alkalis, salt, nitric and sulfuric acids. Such pipes possess perfect mechanical qualities: hardness, wearing resistance at heating, and the lowest thermal coefficient of expansion among metals. Tungsten differs with very high module of elasticity and tensile, unique resistance to thermal creep, good heat conductivity.
Durable operational use of tungsten pipes is much higher than in pipes made of other metals. Primarily, it is conditioned by material strength, resistance to loads, chemical inertness.

Tungsten is very rare element of lithosphere. It is very hard and insufficiently malleable in standard conditions. Difficulty of its obtaining in pure state and heavy treatment increase prime cost of final product.
Manufacture
Tungsten pipe is manufactured on close control equipment out of certificated blanks. While manufacturing, there are used modern technologies of chemical treatment and finishing, vacuum tools for thermal treatment. Manufacturing quality control is performed at all steps of manufacture. The main pipe gauge is 0.15−35 mm of diameter and 0.05−10 mm of wall thickness.
Application
Fast development of nuclear power engineering, instrument engineering, chemical, petrochemical, motor-vehicle industries, electronics increases a demand on refractory pipes. A need in molybdenum or tungsten pipes is evaluated in tones. It is impossible to go without refractory metals (list of which heads tungsten) in manufacture of heat resistant blocks and parts that are intended to be operated in aggressive liquid and gaseous atmospheres. Steady growth of need in tungsten pipes is noticed in air-space industry, nuclear-power, mechanical, electrical engineering, defense industry, medicine.
