Bell end fittings offer a convenient alternative to buttweld fittings by simplifying and speeding up the installation process while still ensuring a robust connection. These fittings reduce installation time since they eliminate the need for extensive preparation, such as beveling connections before welding. They also accommodate minor misalignments in the piping system without compromising joint integrity. With less welding required, bell end fittings help lower labor costs and expedite the installation process.
