Difference Between Socket Weld and Butt Weld

 

Difference between Socket Weld and Butt Weld

Pipe flanges, fittings, and valves can be connected in a variety of ways, including socket weld, butt weld, threaded, and so on. Socket welding and butt welding are two of the most common. However, you may be unsure which one is best for your infrastructure projects because they both appear to use their own set of advantages and disadvantages. As a result, we've taken on the task of making a comparison between them.

 

Socket Weld

They are made in line with ASME B16.11 standards. A pipe would be put into a recessed region of the fitting, or socketed to have a plain spigot end, in the construction of this type of connection. Socket Welding pipe fittings are utilized for combustible, hazardous, or expensive materials in which no leakage is allowed, as well as steam between 300 and 600 psi. SW pipe fittings are a type of high-pressure fitting that comes in multiple pressure rating systems: 3000, 6000, and 9000.

 

Butt Weld

They are made in line with ASME B16.9 standards. Each foot of the valve is sharpened to meet the depth and bevel of the pipe during the butt welding procedure. The two ends are then butted jointly and combined to the channel. The width would just be the same as for the pipes in this situation. Titanium pipes, duplex steels, and nickel-based alloys are all essentially butt welded.

 

Difference between Socket Weld and Butt Weld

  1. Welding grooves and seams of various types

Socket welding created a fillet weld during the welding process. Butt welding is superior to socket welding when considering factors such as weld strength, force conditions, and so on.

  1. Various applications

Because socket weld fittings are only half as strong as butt weld fittings. Socket welding is mostly used for piping with tiny diameters (Small Bore Piping), often piping with a nominal diameter of NPS 2 or less.

  1. Types of detection

In general, butt welding and testing standards are more stringent than socket welding and testing requirements.

To ensure that there are no leaks, the butt welding must be 100% tested, and radiographic inspection is required, but for socket welding, electromagnetic particle detection or infiltration detection is sufficient.

  1. Various costs

Socket weld fittings are more expensive than Butt welding fittings of comparable size. Butt welding fittings, on the other hand, require an additional expense because they are more difficult to manufacture and line up properly. This would take more time and would necessitate the use of qualified welders.

 

Conclusion

To summarise, socket welding has a higher pressure level and even a higher cost than butt welding. Butt welding is an alternative when welding technology is necessary and fully meets the construction standards. If the pipeline medium does not require welding, socket welding is advised since it is simple to detect.
