ISO flanges and piping can be used in various applications ranging from atmospheric pressure to high vacuum, often requiring assembly and disassembly.
The diameter of a typical pipe exceeds 50mm (2 inches). If a fluororubber O-ring is used, it can withstand baking at 150 ℃.
The two commonly used forms of ISO flanges are ISO-K and ISO-F. ISO-K and ISO-F vacuum fittings are large-sized vacuum fittings, with nominal diameter sizes including: DN 63, 100, 160, 200, 250, 320, 400, 500, and 630
Manufacturing standards include: DIN 28404 ，ISO 1609。 Can be applied in situations where a vacuum degree of up to 10-8 mbar is required. The flange sealing material is usually Viton Buna、 Silicone、EPDM、 Aluminum wire, etc. Flanges are usually made of 304, 316 stainless steel, etc
ISO-K vacuum joints typically consist of flanges, flange clamps, O-ring seals, and centering rings.
ISO-F vacuum joints are usually composed of flanges, O-rings, and centering rings. Unlike ISO-K, the flanges are sturdy with bolts.
