Rohren are cylindrical structures commonly used in various applications, including construction, plumbing, and manufacturing. They can be made from different materials such as metal, plastic, or concrete, depending on their intended use. Rohren serve essential functions, such as transporting fluids, providing structural support, or serving as conduits for electrical wiring. In engineering, the design and specifications of Rohren are crucial for ensuring safety and efficiency. Factors like diameter, wall thickness, and material strength are considered to meet specific requirements. Rohren are also integral to systems like HVAC and water supply, where they facilitate the movement of air and water.
