What is a common method used for joining pipes in a boiler system?

1. Screwing

2. Welding or using threaded fittings

3. Clamping with brackets

4. Using adhesives

The correct answer is: Welding or using threaded fittings

Welding or using threaded fittings is a common method for joining pipes in a boiler system due to several important factors. Firstly, welding provides a strong, permanent bond that is essential in systems that require high pressure and durability, such as those found in boiler applications. The welded joints can withstand significant thermal and mechanical stresses that are often experienced during operation, reducing the risk of leaks or failures. Threaded fittings, on the other hand, offer the advantage of being able to connect pipes easily without needing specialized equipment like welders. This can be particularly useful for maintenance and repairs, as fittings can be unscrewed and replaced without the need for extensive downtime or sophisticated welding processes. Both methods are reliable and widely accepted in the industry, ensuring that the pipe systems can operate safely and efficiently. Other joining methods, like clamping with brackets or using adhesives, do not provide the same level of strength or reliability under the demanding conditions found in boiler systems, making them less suitable for this application.
