High Performance Materials
Ta/Nb/Zr/Ti heat exchangers from ULVAC use welds developed from vacuum techniques and are subject to a rigorous inspection system. ULVAC can boast of over 40 years of achievements in the manufacture of heat exchangers, and its products are highly rated in the chemical, pharmaceutical, and nuclear industries.
In-house control value: Base material + 40 HV
|Base material||Welded portion||Difference|
In-house control value: O, N = Base material + 100 ppm (Unit: ppm)
The values below are officially recognized in the processes from “dissolution” through “rolling” to “welding” for Ta products of ULVAC. All processes are conducted in our plants.
