Which type of joint should be used to connect pipes in high-temperature applications?

In high-temperature applications, welded joints are particularly suitable due to their ability to create a continuous and strong connection between pipes. This type of joint involves fusing the materials of the pipe ends together, which results in a bond that can withstand the stress and thermal expansion associated with high temperatures.

Welded joints provide several advantages in such situations: they have a higher resistance to the forces exerted by thermal expansion, pressure, and mechanical stress. Additionally, welded joints eliminate potential leak paths, which is crucial in applications where fluid containment is critical, such as in power plants or industrial processes involving steam and other high-temperature fluids.

Other joint types, such as screw joints, flanged joints, and slip joints, may not provide the same level of durability or sealing capacity required in high-temperature environments. These alternatives can be more prone to leaks and may not hold up as well under thermal stress, making welded joints the preferred choice for reliable and long-lasting connections in those instances.
