Butt Weld (Buttweld) Fitting

A butt weld fitting is a pipe fitting that can be welded to change the direction of flow, branch off, reduce pipe size, or connect ancillary equipment

 


Shape


Butt weld fittings are available as elbows, tees, caps, reducers and outlet fittings (olets). These fittings are the most common type of welded fittings and are specified by nominal pipe size and pipe table. Butt-weld fittings use seamless or welded pipe as a starting material and are formed (through multiple operations) into shapes such as elbows, tees, and reducers.


90 Elbow: A fitting that changes direction in a piping system is called an elbow. The direction change is in degrees, such as 45 or 90. For long radius 90 degree elbows the centerline of the elbow is 1.5 x NPS from the end of the elbow. The centerline of a 3R elbow is located 3 x NPS from the end of the elbow.
45 elbow: the long radius 45 degree elbow changes direction by 45 degrees.
Tee: Butt Weld Pipe Tees allow for a 90 degree branch from a running pipe. This allows auxiliary equipment to be connected to the pipeline. The tee is welded on both sides of the pipe; leave the branch to open the branch.
Reducer: Concentric reducer is also called welded concentric coupling. It allows large pipes to be joined to smaller pipes by welding. Concentric reducers allow a welded connection between two pipes that have the same centerline.
Welded stub ends: stub ends are used with lap flanges for welding to pipe.


Advantages of Butt Welding Fittings


Solder connections provide a more stable connection
Continuous metal structure adds strength to the piping system
Butt weld fittings with matching pipe gauges provide seamless flow within the pipe. Full penetration welds and properly installed 90° elbows, reducers, concentric reducers, etc. provide gradual transitions through welded fittings
Various turning radius options using short radius (SR), long radius (LR) or 3R elbows
Save money compared to their expensive threaded or socket weld counterparts


application


Butt Weld (BW) fittings are used to connect with pipes to deliver natural or propane gas, water, steam and air to residential, building and manufacturing applications.


Manufacturing of Butt Welding Fittings


Butt weld fittings are made through a thermoforming process that involves bending and forming. The starting material for butt weld fittings is a tube that is cut to length, heated, and dyed into a specific shape. Heat treatment is also performed to relieve residual stress and obtain the desired mechanical properties. Read below for more details on the fabrication of butt weld fittings.
For pipe fittings manufacturers, the forming process of welded pipes is basically the same as that of seamless pipes. The forming process of butt-welded pipes does not include the welding process; the other is the welding process required for the pipe fittings to be completed by the pipe fittings manufacturer. Welding flange is a kind of flange pipe fittings. It is widely used and promoted in different fields and industries. The scope of application in use is different, and the environment that needs to be used is also different. It needs to be used according to certain conditions. Butt-welding elbows are completed by welding two steel plates. Generally, large-diameter elbows are made of this process. Generally, those with diameters above 600 are basically butt-welding elbows.
Different pipe fitting product standards have different regulations on heat treatment. Not all deformed fittings are heat treated. Wall thickness 2-55, transportation mode car, train, ship. The packaging method is bundled, and the cracks are painted. Scale weight and theoretical weight. The purpose of heat treatment is to eliminate work hardening, residual stress, metal deformation defects, etc. caused by the forming process, so that the metal structure and performance of the pipe after forming will change, and the state before deformation processing will be restored or its performance will be improved.
