Difference between flat welding flange and butt welding flange:
1.Welding method
In the name we can clearly see the difference between the two: flat
welding and butt welding. Specifically, the pipe diameter and wall
thickness of the joint end of the flat welding flange are the same
as the pipe to be welded, and they are welded together in a flat
way. The butt welding flange is a recess with a slightly larger
diameter than the outer diameter of the pipe. The pipe is inserted
in the socket and then welded.
2.On materials
Compared with Ningbo butt-welded flanges, flat-welded flanges are
simpler in structure, use less material, and have less rigidity and
tightness than butt-welded flanges. Generally, it is mainly used in
the connection of medium and low pressure vessels and pipelines.
3. Processing
The butt welding flange adopts a punching die to punch into a
half-ring elbow or a casting mold to directly cast into a half-ring
elbow, and then two half-ring elbows are welded in groups. The flat
welding flange uses a gasket, which is a ring made of a material
that can produce plastic deformation and has a certain strength.
