What are the main advantages of a lap-joint flange?

A lap-joint flange is specifically designed to address issues with alignment in piping systems. This type of flange consists of a stub end and a lap joint flange, allowing for a more flexible alignment capability when connecting two segments of a pipe. This is particularly advantageous in systems where pipe ends may not be perfectly aligned due to thermal expansion, vibration, or installation tolerances. The design allows for the flange to be positioned in a way that accommodates misalignments, enabling better overall system performance.

While ease of installation, cost-effectiveness, and rust resistance are relevant factors in flange selection and may apply to some contexts, the primary advantage of a lap-joint flange directly relates to its ability to handle alignment issues effectively. Thus, it stands out as the most significant benefit in applications where achieving precise alignment is challenging.
