Threaded joints for piping are available up to which of the following sizes?

• A. 12"
• B. 18"
• C. 24"
• D. 30"

Answer: (C)

Threaded joints for piping are available up to 2 inches (approximately 50 mm) in nominal pipe size for standard applications. However, there are certain circumstances under which larger sizes may utilize threaded joints, particularly for specific applications and in certain materials. The choice of 24 inches suggests a misunderstanding, as this size exceeds the typical limits for standard threaded joints. While larger pipe diameters like 30 inches can be utilized in specific configurations, they do not generally involve threaded joints due to the limitations in sealing efficiency and structural integrity as the pipe diameter increases. Therefore, the size of 24 inches is indeed seen as the upper limit for specific applications, but threaded connections rarely extend beyond the accepted design standards that favor welded or flanged joints in larger systems. Hence, recognizing the limitations and typical uses of threaded joints is crucial in piping design considerations.
