How are low pressure steam pipes commonly joined together?

Low pressure steam pipes are commonly joined together using screwed fittings. This method is favored due to its practicality and ease of installation. Screwed fittings allow for quick connections and disconnections, which can be essential for maintenance and servicing of the system.

In low pressure applications, the use of threaded pipes and fittings is also suitable due to the relatively low mechanical stress involved. The threads create a secure connection that can effectively handle the pressures typically found in low pressure steam systems.

While other methods, such as bolted flanges or welding, are used in various piping applications, they are typically more common in high-pressure or larger diameter pipes where the demands on the joints are greater. Reducing bushings serve a different purpose; they are used to connect pipes of different diameters rather than for the primary joining of low-pressure steam pipes.
