Due to the fact that most pipe fittings are used for welding, in order to improve welding quality, the ends are turned into grooves with a certain angle and edges.

This requirement is also quite strict, with regulations on the thickness of the edges, the angle and deviation range.

The surface quality and mechanical properties are basically the same as those of pipes.

For the convenience of welding, the steel grade of the pipe fittings and the connected pipes is the same.
