What are the characteristics of a flat weld flange?

A flat welding flange is a type of flange that is connected to a vessel or pipeline through angular welding. Flat welding flanges are widely used for the connection of medium and low-pressure vessels and pipelines. The production process of flat welding flanges includes forging from pure materials, wool forging suitable for flat welding and butt flanges, steel plates for flat welding flanges, and centrifugal casting and cast flanges.

1. The flat welding flange saves space and weight completely. Importantly, it ensures that the joint will not leak and has excellent sealing performance. The diameter will re-seal the cross-section of the face.

Secondly, the法兰垫圈 has been replaced by a sealing ring to ensure a proper match between sealing surfaces. This allows the cover to be compressed with minimal pressure, reducing the required pressure. Consequently, the size and quantity of bolts can be individually refined, leading to the development of a new product with a smaller volume and lighter weight (up to 70% to 80% lighter than traditional flanges). As such, the flat welding flange is a relatively high-quality flange product that reduces both weight and space, playing a crucial role in industrial applications.
