End Bell is used in concrete vault wall to provide a smooth, safe entrance to the conduit outside. They protect wiring which is being pulled through the vault wall. An End bell is a socket that ideally suits to connect one end of the pipe to the one end of the other pipe.

End bell pipe fittings are easier to install than conventional butt welding pipe fittings and can be welded four to seven times faster than the standard butt welding fittings. The wrought cold formed belled end pipe fitting eliminates the problems of misalignment and wall thickness mismatch that are inherent to butt welded joints.

Testing has proven that belled end pipe fittings are equal in burst and superior in fatigue. Manufactured from pipe with starting wall thicknesses that is very close to the actual pipe wall nominal thickness, the belled end pipe fitting when joined to pipe, creates a flex continuum.

When a belled end pipe fitting fillet joint is installed in applications involving pipe flexing and vibrations, a longer life cycle can be expected. These can be manufactured from full finished, annealed and pickled minimum wall welded and seamless pipe. The latest cold forming techniques are used to produce belled end pipe fittings of superior quality and reliability.
