In industrial production and scientific research exploration, the demand for high vacuum environment is urgent, and CF BORED FLANGES plays a core role.
The flange adopts an integrated structure with no moving parts, eliminating the risk of sealing failure caused by loose parts. The sharp blade on its inner side is the key to sealing, and during installation, it squeezes oxygen free copper or other soft metal gaskets, which deform and fill the gap.
The main body is made of austenitic stainless steel such as 304L, 316L, and 316LN, which have high strength, corrosion resistance, low gas release rate, and maintain high vacuum environment stability. Such as 316LN stainless steel, with a Brinell hardness of about 170, after electroslag remelting treatment, the grain size is uniform, the magnetic permeability is low, and it is suitable for frequent disassembly and magnetic sensitive scenarios.
There are multiple types of sealing gaskets, and oxygen free copper gaskets have excellent sealing and temperature resistance, suitable for high vacuum; Silver plated gaskets have lower oxidation resistance and air release rate, making them suitable for high-temperature baking; Baking temperature below 200 ° C, aluminum gasket is economical and practical.
