Easy installation and good alignment:

When the pipe is inserted into the socket, a preliminary alignment is achieved automatically, which simplifies the alignment process during installation. This is especially suitable for on-site installation or in locations with limited space.

Relatively small welding workload:

Compared to butt welding, which requires full penetration welds, the fillet welding for socket weld flanges involves a smaller workload. This means slightly lower skill requirements for the welder and easier control of welding-induced deformation.

High structural strength:

Once the welding is complete, the connection point exhibits high resistance to bending and vibration, and the joint strength can even exceed that of the pipe itself.

Suitable for small-diameter pipelines:

For smaller-sized piping systems (typically with a nominal diameter below DN50), socket weld flanges are a more economical and practical option than butt weld flanges.
