Technical features
Tubes of particularly small diameters are called capillary tubes. Because tungsten and tantalum alloys of TV grade have high heat transfer coefficient, such capillary tubes are used in production of parts of heat exchange circuits. Small dimensions of capillary tubes of TV-5, TV-10 and TV-15 tantalum-tungsten alloys under TU 48-4-311-74 provide their use in machines and equipment of chemical production.
Production of .
The technology of their production consists in the following. The initial ingot of tantalum-tungsten alloy is heated to the melting point, after that the metal is rolled or drawn on the drawing mill. The end product is a hollow product with the required diameter.
Sequence of capillary tube production
- - Homogenizing annealing of ingots at temperatures of 1300±50ºC;
- - Copper coating, which increases heat transfer at high usage temperatures;
- - Hot extrusion of material on hydraulic rod-piercing presses;
- - Rolling in a roller mill;
- - Protective coating.
- - Finished tubes are subjected to recrystallization annealing at 950 ... 1050°С, after that they are calibrated to obtain the required wall thickness.
Supplier Evek GmbH offers to buy tantalum-tungsten tube of alloys. TV-15, TV-10, TV-5 at reasonable price in wide assortment. Provide product delivery anywhere in the continent. The price is optimum.
Features and assortment
Alloys of tantalum with tungsten TV-5, TV-10 and TV-15 have high melting point, ultimate tensile strength and high corrosion resistance. They are manufactured using energy metallurgy techniques by mixing tantalum powder with alloy elements and filling them into molds, followed by pressing under increased pressure. The corrosion resistance of tantalum-tungsten alloys is preserved by heating up to 1600 °C.
Capillary tube sizes TU 48-4-311-74
- Outer diameter: 1,0 ~ 150 mm
