Olet

Olets, also known as Branch Fittings, are forged fittings used to create connections from a run pipe to an outlet pipe at either 45 or 90 degrees. The appropriate run size of the Olet is selected based on the NPS of the header pipe. Then, using the ID of the Olet as a template, a port in the header pipe is cut and the Olet is welded in place. Based on the requirements of the branch, there are several different styles of Olet.

Weldolets are the most commonly used branch fitting. They have a beveled end at which they’re welded to the branch pipe at a 90° angle. The shape of the Weldolet ensures little stress concentration on the branched pipe, providing an integral reinforcement. Sizes are based on pipe schedules.

Socolets are nearly identical to Weldolets, the main difference being that the branch pipe is inserted into the socket and welded in place. They’re classed as pressure fittings, available from 3000# to 9000#.

Threadolets attach to the branch pipe at a 90° angle via thread. Available in classes 3000# and 6000#, Threadolets are used for smaller pipe sizes and low-pressure applications.

Latrolets attach to the branch pipe, typically at a 45°angle, but are also available at 60°. They are available with butt weld connections, or with socket weld or threaded connections in classes 3000# or 6000#.

Nipolet are essentially Olets with 90° Swage Nipple branches. The outlets are either beveled, grooved, square cut or threaded, and are available in pipe sizes between ½” and 6”, in all pipe schedules. Typical length of the fitting is 3.5”.

Elbolets are designed to be welded to an elbow header. Threaded and butt weld Elbolets are available in pipe sizes between ½” and 6”, in all pipe schedules. Socket weld Elbolets are offered in in classes 3000# or 6000#.
