The 3D design of a long pipe with valve showcases an extended pipeline integrated with a control valve, ideal for regulating fluid flow over a significant distance. The model features a straight pipe segment connected to a centrally placed valve—such as a gate, ball, or butterfly type—allowing precise flow control within the system. Flanged or welded connections ensure durability and leak-free operation, while the design accommodates industrial standards for pressure and temperature resistance. This configuration is commonly used in water supply, oil and gas, and chemical processing applications.
