ISO-CF-Flange Components

For the requirements of high and ultra high vacuum as well as of high temperature, CF-flanges are the solution as they seal by metal seals. In order to achieve leakproofness, flanges comprise knife edges who penetrate the copper seal, forming an annular groove.

These flanges are available in stainless steel grades 304L, 316L or 316LN. Sizes from DN16 to DN250. Pressure range is from atmosphere to 10-12hPa. The material 316LN is of lowest magnetically permeability and keeps the knife edge under annealing at 1050oC. Degassing is possible up to 450oC when screws and sealings are designed for this temperature.
