Weldolets
Weldolets are the most common branch connection fittings, designed for butt-welding onto outlet pipes with beveled ends, minimizing stress concentrations and providing integral reinforcement.
Widely used in oil and gas, petrochemical, and power generation industries, Weldolets ensure strong and reliable branch connections in high-pressure piping systems.
Weldolets are butt-weld fittings that facilitate branch connections by welding directly onto the run pipe, with beveled ends ensuring a smooth and strong weld joint. Their design reduces stress concentrations at the connection point and provides integral reinforcement, making them ideal for high-pressure and high-temperature applications. Available in various materials and sizes, Weldolets are versatile for creating branch outlets in piping systems, offering superior strength compared to other branch fittings like threadolets or sockolets.
Weldolets are manufactured to meet stringent industry standards, ensuring compatibility and performance in demanding piping systems.
