Buttweld Fittings
Buttweld Fittings
Buttweld fittings are defined in the ASME B16.9. They are welded at their ends to pipe end, with the same thickness as pipes. Buttweld fittings are pipe fittings used to change the pathway of Pipeline.
Buttweld fittings are used for piping systems above 2 inches in diameter, they are available in multiple shapes and dimensions.
Buttweld fittings have the benefits such as allow strong, and leak proof piping connections. It minimizes pressure drops and the turbulence inside the pipeline. It has a long life and it cheaper to purchase and deploy.
