Flanged joints are typically used for joining which type of pipes?

Flanged joints are specifically designed for applications involving large-diameter pipes, especially in industrial settings. This type of joint allows for easy assembly and disassembly, which is essential in settings where maintenance and repair are common. The flanges create a tight seal when bolted together, facilitating the safe transport of high-pressure fluids or gases.

In industrial applications, where pipes can be quite substantial in size, flanged joints provide the necessary structural integrity and support. This contrasts with other types of joints that may not be suitable for the sheer size and pressure conditions often encountered in large industrial pipe systems. Moreover, flanged joints accommodate the need for alignment and allow for expansion and contraction of the piping systems, which is critical in environments where temperature fluctuations occur.

The other types of pipes—plastic pipes for drainage, conductive electrical pipes, and small-diameter household pipes—are typically joined using different methods such as solvent welding, threaded connections, or compression fittings, which are more appropriate for their size and usage scenarios.
