Which flange type is best suited for applications requiring frequent maintenance?

The slip-on flange is highly suitable for applications that require frequent maintenance due to its design and installation characteristics. It is designed to slip over the pipe and is welded in place, which allows for ease of installation and replacement. This feature simplifies the process of disassembly and reassembly, making it ideal for situations where regular access to the pipe connection is needed, such as maintenance and inspections.

Additionally, the slip-on flange is generally less expensive and easier to align than other flange types, which contributes to its practicality in maintenance-intensive environments. In contrast, flanges like the weld neck flange require more elaborate fittings and might be more cumbersome to remove because they are welded directly to the pipe, making them less convenient for repeated access.
