2018-03-14

Flat Welded Flange For the most aggressive media, the most commonly used is acid resistant asbestos. In high-voltage equipment and pipelines, lens-type or other-shaped metal gaskets made of copper, aluminum, No. 10 steel, and stainless steel are used. The contact width between the high-pressure gasket and the sealing surface is very narrow (line contact), and the sealing surface and the gasket have a high processing finish.
