A Weldolet is a butt-weld branch connection. It is designed to provide integral reinforcement and minimize stress. They are made to match or exceed the schedule of the pipe.
wildly welding main pipe the are fillet weld or butweld
To be fully welded out plus a fillet of @ 6mm to reduce the stress concentration factor at the bottom toe.
Weldolets and socolets are used in piping systems to create branch connections efficiently. Weldolets are typically welded to the main pipe, providing a strong and durable joint for higher pressure applications, while socolets are designed for socket weld connections, making them easier to install in tight spaces. Both fittings help minimize stress concentrations and ensure a smooth flow of fluids, enhancing the overall integrity of the piping system. Their use is critical in maintaining safety and reliability in various industrial applications.
There are size on size weldolets. The hold on the run pipe will necessarily be undersize (either hot tap or torch ) because it's not possible to cut the same size hole in the run without damaging the base material.
Yes, a weldolet is a type of butt weld fitting used in piping systems. It is designed to provide a branch connection to a main pipe, allowing for a seamless flow of fluids. Weldolets are typically welded to the main pipe using a butt weld, ensuring a strong and secure joint. They are commonly used in various industries for their ability to minimize stress concentrations and maintain the integrity of the piping system.
Weldolet is a trademarked name by Bonney Forge for internally reinforced forged branch outlet fittings. Pipet is a trademarked name by WFI for internally reinforced forged branch outlet fittings. Both comply with MSS SP-97 Internally Reinforced Forged Branch Outlet Fittings - Socket Welding, Threaded and Buttwelding Ends. Referenced in ASME B31.3-2020 304.3.1 a) (1). They are the same
Weldolet and Sockolet are basically self reinforced fittings. Weldolet is used for Butt weld branch connection where standard tee is not available due to size restrictions and the piping is of critical / high pressure service. Sockolet is used for socket welding branch connection, which require reinforcing pad.
