What is one advantage of a lap-joint flange?

1. Easy to replace

2. Helps fit up where alignment is a problem

3. Cheaper than standard flanges

4. Requires fewer bolts

The correct answer is: Helps fit up where alignment is a problem

A lap-joint flange is specifically designed to accommodate pipes that cannot be precisely aligned. This type of flange allows for some flexibility in fitting up sections of piping where traditional flanges may not align perfectly due to variances in installation, deformation, or other factors. By using a lap-joint flange, a fitting can be made that simplifies the assembly of pipes, making it easier to connect sections without requiring perfect alignment. This flexibility is especially beneficial in environments where adjustments and fittings need to be made due to space constraints or when joining equipment that may not be perfectly located concerning the pipe's layout. While numerous other advantages exist for lap-joint flanges, such as their potential cost-effectiveness or ease of replacement, the core benefit pertinent to this question lies in their ability to address alignment issues effectively. This makes them invaluable in ensuring efficient and functional piping systems.
