Range of tubes from tantalum of domestic production

Two varieties of tantalum tubes are produced by enterprises:

  • Capillary tubes of small diameters, used in chemical engineering equipment:
  • Thick-walled seamless tubes of HFI grade, which are produced by pressing with subsequent rolling of the semi-finished product in a cold state:
Grade Base Tungsten, not less Other elements, not more, %
TV-5 Tantalum W - 4-6% Nb - 1, Ti, Fe, Si, C, N, O - 0,01 each, Mo - 0,1, H - 0,001
TV-10 W - 9-11%
TV-15 W - 13,5-16,5%
Pipe, mm (diameter/thickness) Basic element, % Impurities, not more, %
10-20/1,7; 20-30/1,8 Ta - 99,8

Nb - 0,1, Fe - 0,005, Ti, H - 0,001 each, Si - 0,003, W+Mo, O - 0,015, Co - 0,0001, Ca- 0.002, Na, Mg, Mn - 0.0003, Ni, Zr, Sn - 0.0005, Al - 0.0008,Cu, Cr - 0.0006,

Calculation technique

It is known that the density of tantalum is, depending on the chemical purity of the metal, from 16.6 to 16.7 g/cm3. In order to know the weight, we apply the following formula ρ-π-(R21 - R22)-l, where

  1. ρ - specific gravity = 16.65 g/cm3
  2. π = 3,1415926
  3. R1 - outside diameter;
  4. R2 - inner diameter;
  5. l - product length.

For a meter-long tube of 1 mm thickness and 20 mm diameter, we get the result. 993.8 grams.
