A flat welding flange is a commonly used flange fitting in pipeline connections, typically consisting of two flanges and several bolts, washers, and other components. The main materials for this product are carbon steel, stainless steel, alloy steel, etc., which can be selected according to different working environments and requirements. Flat welding flanges are usually used for pipeline connections, with the two flanges welded together flat face to flat face to form a tight connection, ensuring the safe operation of the pipeline system.

Common Types:
1. Standard flat welding flange: a flat welding flange manufactured according to international standards (such as ANSI, DIN, JIS, etc.), commonly used to connect pipes and equipment according to the corresponding standards.
2. Long neck flat welding flange: a flange with a longer neck, suitable for some special pipeline connections.
3. Short neck flat welding flange: a flange with a shorter neck, suitable for general pipeline connections.
4. Machined flat welding flange: a flange with a machined surface, with a flatter surface and better sealing performance.
5. Small diameter flat welding flange: suitable for small diameter pipeline connections.
6. Large diameter flat welding flange: suitable for large diameter pipeline connections.
