Seiler Vakuumtechnik GmbH is a manufacturer of Helium leak detection systems and special - purpose equipment.

Pressurized leak detection method for storage tank was developed for the characteristics of space storage tank with a complicated structure and strictly controlled leak rate.

Using the helium mass-spectrometer leak detector to detect the leak of seams between the tube and face-flange and measure the total leakage rate are introduced in this paper.
