vacuum tube
The evacuated tubes are made in high quality boronsilicon glass It can endure 0,6Mpa pressure and the hail which is smaller than 25mm The absorption is boosted by a Nitrogen and Aluminum solution sputtered in the space between the two pipes. The rate of absorbingis more than 0,92.The tubes exist different diameters: Φ47, Φ58,Φ70 -800mm, 1200mm, 1500mm, 1600mm,1800mm, 1900mm, 2000mm, 2100mm.The rate of vacuum between the pipes is below 5*10-3Pa which is the best rate currently available for evacuated tubes. The average pressure in the market is 5*10-2P
