welding procedure of the flange connection
Dec 01, 2017

The flange connects the two pipes, equipment and fittings. First, each is fixed on a flange plate. Add the flange pad between two flange plates and fasten them with the  screw bolts. So that the connection can be completed.
In the process of connecting, some equipment and pipe fittings are equipped with flange plates. Flange connection is an important connection way of piping installation. Flange connection is very convenient in the use process, which can bear greater pressure.

According to the connect kinds, the flange connection can be divided into the screw flange, blind flange, slip on flange, socket welding flange, welding neck flange, downward welding loose flange, groove flange, major diameter hubbed flange, figure 8 blind and so on.

The welding procedure of the flange connection:
The vertebral body and the large flange are assembled together according to the drawing requirements, and the large flange is divided into 8 equal parts. Because the flange is thicker, the groove is larger, so using the piecewise symmetry and multilayer welding.
