The biggest difference in structure between slide-in flanges and butt-welded flanges is that they are connected to the flange in different ways. Advantages: Flat-welded flanges with necks are also flat-welded flanges, because there is a short neck, which increases the strength of the flange and improves the bearing capacity of the flange. So it can be used on higher pressure pipelines.
Disadvantages: Compared with the plate-type flat welding flange, the cost is higher, and it is easier to bump during transportation due to its shape characteristics.

The connection method of the neck and the flat welding flange is generally to use the flange corner connection, the flange to the flange connection flange connection flange connection pipe butt connection.
