These fittings, clamps, and junctions are also known as pipe fittings. The three most common types of weld fittings are tube clamps, tube connectors, and elbow joints. With pipe butt welding fittings, pipe and tube systems of different diameters can be joined. The number of butt joints required depends on the size of the system. End joints are fused or butt welded to prevent leaks. Tubes
A welding process connects the ends of fittings or pipes. It is possible to branch off a pipe, change the flow direction, attach auxiliary equipment, or reduce the diameter of a pipe with weldable steel pipe fittings. ANSI/ASME B16.9 specifies that forged steel butt weld fittings are manufactured.
Fittings with butt welds have beveled ends A beveled end is required on all butt weld fittings according to ASME B16.25. This would enable a full penetration without further preparation. The most common materials used to make these types of fittings are stainless steel, carbon steel, alloy steel, aluminum, nickel, and high-yield steel.
