A butt weld pipe fitting is designed to be welded on site at its end(s) to connect pipe(s) together and allow change in direction or pipe diameter, or branching or ending.
This fitting then becomes part of a system for transporting fluids (oil, gas, steam, chemicals, …) in a safe and efficient manner, over short or long distances.
A lap joint flange is a two component assembly, with a stub end that has a lap joint ring flange placed over it. The stub end is then butt welded to the pipe, and the flange ring can be rotated to align with the mating flange. This type of flange connection is particularly useful for large or hard to adjust flanges.A lap joint flange is a two component assembly, with a stub end that has a lap joint ring flange placed over it. The stub end is then butt welded to the pipe, and the flange ring can be rotated to align with the mating flange. This type of flange connection is particularly useful for large or hard to adjust flanges. The lap joint flange can be used in sizes and pressure classes similar to that of a weld neck flange.
The nature of this joint means that the stub end facing is also the flange facing, which makes it raised faced, and the gasket seating surface.
