Product Description
DIN 2573 Slip On Flange is a widely used type of plate flange designed according to the German DIN standard. It features a low-pressure rating (typically PN6 or PN10), and is suitable for non-critical, low-pressure applications such as water, gas, or air pipelines.
Manufactured from carbon steel or mild steel, this flange is slipped over the pipe and then fillet welded on both sides, ensuring a secure and leak-proof connection. It’s ideal for pipeline systems that require frequent inspection or maintenance, due to its ease of installation and removal.
