Weldolet

A Weldolet is a type of pipe fitting used for branch connections on pipes.

It is designed to fit over the run pipe and be welded onto it, with a branch pipe connected to the other end. This creates a strong and permanent connection between the pipes, making it an efficient and durable solution for piping systems.

A Weldolet is the most common type of branch connection, typically welded onto the outlet pipe. The ends are beveled to facilitate the welding process, classifying the Weldolet as a butt-weld fitting. Weldolets are crafted to reduce stress concentrations and offer integral reinforcement.

Branch connection fittings encompass more than just tees and laterals; they also include Weldolets. Weldolets are welded branch connections designed to match or surpass the schedule of the pipe used. Each is labeled with an outlet size and the pipe sizes it can be welded to. For instance, if marked as 5-3×3/4", it has an outlet size of 3/4" and fits pipe sizes 3", 3 1/2", 4", 5", with a maximum gap of 1/32" for the largest size. Regardless of your pipe size, there is an Olet available for the job. Olets with a size of 4 inches or smaller are designed to fit various pipe sizes, while those with a size of 5 inches and larger are designed for specific pipe sizes. A flat base is available for connecting to pipe caps and vessel heads.

A Weldolet creates a 90° branch connection and is available in full size or reducing options for a straight section of pipe. The designation of a Weldolet is based on the run length and the branch length. For instance, a 6-inch Weldolet on a 10-inch pipe would be labeled as a 10x6 Weldolet. Weldolets are engineered to minimize stress concentrations and provide integral reinforcement without the need for additional weld reinforcement.

Weldolet is olet pipe fittings that can supply an outlet from a larger pipe to a smaller pipe in piping & tubing systems. The Weldolet Forged Pipe Fittings are the most common type of olet branch connection fittings which is ideal for high pressure and high-temperature applications. ASME B16.11 Weldolet can easily be installed on run pipe and welded with buttweld techniques.

Weldolet Buttweld Pipe Fittings expedite installation and demand less space. We produce these branch connection pipe fittings, known as olets, in various material grades such as Stainless Steel, Carbon Steel, Alloy Steel, Nickel Alloy, and more. Weldolet pipe fittings find significant utility in lengthy connection pipe fittings within various industries.
