What are Flat Welding Flanges?

Flat Welding Flange has two types, Slip-on Flange & Plate Flange.

How to lap welding the flat welding flange?

Pipe need to insert into the flange ID to an appropriate position and then lap welding.

Advantage: It is easy for welding, and the total cost is competitive, so it is widely used.

According to the internal pressure calculation, the strength of the flat welding flange is about two-thirds of the corresponding butt welding flange, and the fatigue life is about one-third of the butt welding flange. Therefore, the flat welding flange is only suitable for pipeline systems with relatively low-pressure levels and low-pressure fluctuations, vibrations and spreading.
