Latrolet — 45° Lateral Branch Outlet
The Latrolet is a forged integrally reinforced branch outlet fitting designed for 45-degree lateral branch connections on pipe runs. Unlike the Weldolet (which exits the run pipe at 90 degrees), the Latrolet is contoured on its base to seat on the run pipe at 45 degrees, directing the branch outlet at a 45-degree angle to the run pipe axis. The forged body provides the full reinforcement required at the branch opening in the run pipe wall, eliminating the need for a separate reinforcing pad, saddle or additional weld metal.
The 45-degree lateral exit angle reduces the turbulence and pressure drop at the branch connection compared to a 90-degree tee or standard outlet, making the Latrolet particularly suited to slurry, high-velocity gas and two-phase flow lines where the abrupt directional change of a perpendicular branch would cause excessive erosion or pressure loss at the connection point. The branch end is available as butt-weld (BW), socket weld (SW) or female NPT threaded to suit the branch pipe connection type.
