The 3D design of a tee pipe with valve and flanges combines a T-shaped pipe fitting with a centrally mounted valve and flanged ends on all three branches for secure bolted connections. This configuration allows for controlled flow in multiple directions, enabling isolation or redirection of fluids within a pipeline network. The integrated valve—such as a gate or ball valve—offers precise shutoff or regulation, while the flanged ends ensure easy installation and maintenance. Ideal for complex fluid systems in industries like oil and gas, chemical processing, and water treatment, the design ensures reliability and operational flexibility.
