TU 48-4-311-74. Tantalum-tungsten alloy tubes. TV-15, TV-10, TV-5
Are you interested in TU 48−4-311−74? We offer to purchase from the specialized warehouses of the supplier Evek GmbH a tube of tantalum-tungsten from alloys. TV-15, TV-10, TV-5 with delivery to any city. Full compliance with modern quality standards. Supplier Evek GmbH offers to buy rare earth metals, the price is optimal in this segment of metal.
Pipes of especially small diameters are called capillary tubes. Since the alloys of tungsten and tantalum of the brand TV are characterized by an increased value of the heat transfer coefficient, such capillary tubes are used in the manufacture of parts of heat exchange circuits. Small dimensions of capillary tubes from tantalum-tungsten alloys TV-5, TV-10 and TV-15 according to TU 48−4-311−74 cause their use in machines and equipment of chemical industries.
The technology for obtaining them is as follows. The initial ingot of the tantalum alloy with tungsten is heated to the melting point, followed by rolling the metal or drawing it on a drawing mill. The final product is hollow articles of the required diameter.
Sequence of manufacturing capillary tubes
- • Homogenizing annealing of ingots at temperatures of 1300 ± 50ºC;
- • Copper coating, which increases heat transfer at high temperatures of use;
- • Hot extrusion of material on rod-piercing hydraulic presses;
- • Running on a roller mill;
- • Application of a protective coating.
- • Finished tubes are subjected to recrystallization annealing at 950… 1050 ° C, after which they are calibrated to obtain the required wall thickness.
Supplier Evek GmbH offers to buy a tube of tantalum-tungsten from alloys. TV-15, TV-10, TV-5 at an affordable price in a wide range. We will ensure the delivery of products to any point of the continent. The price is optimal.
Features and assortment
Alloys of tantalum with tungsten TV-5, TV-10 and TV-15 are characterized by high melting temperature, tensile strength and increased corrosion resistance. They are produced using energy metallurgy technologies by mixing tantalum powder with alloy elements and filling them in molds, followed by pressing at elevated pressure. Corrosion resistance of tantalum-tungsten alloys is preserved by heating to 1600 ° C.
Dimensions of capillary tubes according to TU 48−4-311−74
- Outer Diameter: 1.0 ~ 150mm
- Wall thickness: 0.2 ~ 5.0 mm
- Length: 200 ~ 6000 mm
Tantalum-tungsten alloys are carefully processed to prevent damage during storage and transportation, and to preserve the quality of our products in their original state.
