What are the Benefits of Butt Weld Fittings?

The benefit of using a butt weld fitting is that it doesn’t leak. Because the butt weld is welded directly to the pipe and not simply bolted together, it is not only much stronger than a typical fitting, but it allows for better flow through the system with less resistance to friction. Welded fittings also allow for better layout designs through key features such as being more compact and greater in strength.

Butt Weld Fitting Industrial Applications:

The forged steel fittings and high-pressure fittings are used to conduct pressure tests on assemblies in the oil and gas and a variety of other industries. Buttweld fittings are used for air, water, oil, and natural gas applications. Some of the common industries that use buttweld fittings include:

  • Oil & Gas
  • Petrochemical
  • Alternative Energy
  • Subsea Drilling
  • Construction
  • Mechanical
