Flat flange

Features of plate flat welding flange: the connection between flat welding flange and pipeline is to insert the pipe into the inner hole of flange to an appropriate position, and then lap weld. It is applicable to the pipeline system with low pressure level and no serious pressure fluctuation, vibration and shock. 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.
