BUTT WELD FITTIINGS
The simplest way to alter the direction or function in any piping system is by using a pipe fitting/swept fitting. Pipe fittings/Swept fittings can easily change the direction of flow by maintaining the consistent wall thickness and swept radius resulting in efficient Laminar flow.

Classification and Application:
• Welding a fitting to the pipe ensures it to be leak-proof.
• The weld component between the pipe and fitting adds strength to the system.
• Smooth inner surface and gradual directional changes reduce pressure losses and turbulence and minimize the action of corrosion and erosion.
• A welded system utilizes a minimum of space.
• Conforms to ASME B16.9 & ASTM A234 WPB
