Buttweld Fittings, Butt Welding Pipe Fittings
|What is a Buttweld Fitting?|
Butt welding is a commonly used technique in welding that can either be automated or done by hand on steel pieces. Butt welding can also be done with brazing for copper pieces. It is used to attach two pieces of metal together such as pipe, framework in factories, and also flanges. Butt welding is best performed with MIG or TIG welding applications due to their natural ability to connect two pieces of metal together.
A pipe fitting is defined as a part used in a piping system, for changing direction, branching or for change of pipe diameter, and which is mechanically joined to the system.
There are many different types of fittings and they are the same in all sizes and schedules as the pipe.
Fittings are divided into three groups:
1. Buttweld (BW) fittings whose dimensions, dimensional tolerances are defined in the ASME B16.9 standards. Light-weight corrosion resistant fittings are made to MSS SP43. Butt weld fittings would also be referred to as welded pipe fittings
2. Socket Weld (SW) fittings Class 3000, 6000, 9000 are defined in the ASME B16.11 standards.
3. Threaded (THD) fittings Class 2000, 3000, 6000 are defined in the ASME B16.11 standards.
|Advantages of use of Buttweld Fittings|
A piping system using buttweld fittings has many inherent advantages over other forms.
1. Welding a fitting to the pipe means it is permanently leakproof
2. The continuous metal structure formed between pipe and fitting adds strength to the system
3. Smooth inner surface and gradual directional changes reduce pressure losses and turbulence and minimize the action of corrosion and erosion
4. A welded system utilizes a minimum of space
