Which type of joint is commonly used for connecting metal pipes?

• A. Soldered joints
• B. Welded joints
• C. Compression joints
• D. Flanged joints

Answer: (B)

Welded joints are commonly used for connecting metal pipes due to their ability to create a strong and permanent connection. This method involves melting the edges of the pipes and adding filler material to form a bond as the molten metal cools and solidifies. Welding is particularly advantageous for high-pressure applications as it maintains the structural integrity and pressure rating of the pipe. This technique is essential in industries requiring durable and leak-proof connections, such as oil and gas, chemical processing, and plumbing. While soldered joints are often used for copper pipes and compression joints for easy assembly in various plumbing applications, they do not provide the same level of strength and permanence as welded joints. Flanged joints, while useful for ease of disassembly and maintenance, rely on bolts and gaskets and may not be suitable for all locations or circumstances where a permanent and secure connection is paramount. Therefore, welded joints are the most appropriate choice for connecting metal pipes in scenarios demanding robustness and resistance to leakages.
