How shall steel pipe joints embedded in a building be joined?

Steel pipe joints embedded in a building are typically joined through welding for several reasons related to the integrity and structural requirements of the installation. Welding provides a permanent and robust connection that is essential when the pipes are part of a building’s infrastructure. The weld creates a continuous joint that minimizes the risk of leaks, which is particularly important for carrying fluids or gases under pressure.

Additionally, welded joints are generally stronger than threaded or bolted connections, which is crucial for maintaining the safety and durability of the building's mechanical systems. Since the pipes are embedded within the structure, any potential weakness in the joint could lead to significant issues within the building, such as safety hazards or costly repairs.

While alternatives like screwed, bolted, or soldered joints might be acceptable in certain applications or for smaller pipes, they do not offer the same level of strength and reliability required for embedded steel pipe joints. Therefore, welding is the preferred method to ensure long-lasting performance and structural integrity in these scenarios.
