A Weldolet is a butt-weld branch connection fitting used to create a 90° branch from a main, or "run", pipe.
They are designed to provide integral reinforcement and minimize stress oncentrations, making them ideal for high-pressure and high-temperature applications.
Key Features and Specifications
- Connection Method: A Weldolet connects to both the run pipe and the branch pipe using butt welds. The ends are typically beveled to facilitate this process.
- Integral Reinforcement: The fitting's unique contoured shape provides self-reinforcement, eliminating the need for bulky and less efficient reinforcing pads.
- Size Versatility: Available in both full-size (branch size matches run pipe size) and reducing-size variants (branch size is smaller than run pipe size).
- Pressure Rating: Pressure ratings are determined by the schedule of the pipe they are matched to (e.g., Schedule 40, Schedule 80, Schedule 160, XXS), ensuring the branch connection can handle the same pressure as the main pipe.
- Standards: Manufactured according to industry standards and codes, including ASME B16.9, MSS SP-97, and ASTM A234.
