Product Introduction
Flat welding flange refers to a flange connected with vessels or pipes by fillet weld. It belongs to any type of flange. According to the integrity of the connection between the flange ring and the straight cylinder section, the design shall be checked according to the integral or loose flange. Flat welding flange can be classified into two types: with neck and without neck.
Compared with the neck butt welding flange, the flat welding flange has simple structure and less material, but its rigidity and sealing are not as good as the neck butt welding flange. Flat welding flanges are widely used for the connection of medium and low pressure vessels and pipelines.
Plate type flat welded steel pipe flange and neck flat welded steel pipe flange
The slip-on flange is applicable to the pipeline system with low pressure rating and low pressure fluctuation, vibration and vibration. The advantage of flat welding flange is that it is easy to align when welding and assembling, and the price is relatively cheap, so it has been widely used.
Flat welding flange is not allowed to be directly welded with tee, elbow and other pipe fittings, and straight pipe section is required.
