Slip-on Flange

A slip-on flange with a six-inch diameter is typically utilized exclusively for pipes. In order to connect slip-on flanges, it is typical to utilize two welding techniques: one within the internal aperture and the other external to it. In these flanges, the central hole is of a larger diameter than that of the pipe, allowing the pipe to pass through the middle of the hole and be connected to the flange with a strip weld. The temperature and pressure tolerance of slip-on flanges are typically lower than that of welding neck flanges. One of the most significant factors is that, in this category of flanges, the absence of the neck part results in an unequal distribution of pressure between the pipe and the flange. Consequently, these flanges exhibit diminished resistance over time.
