Others

Slip on flange are usually cheaper than Weld-Neck flange (welding neck flange), which is why many customers prefer to choose them. It is one of the commonly used flanges for low pressure, medium temperature piping system.

On the other hand, since the flange bore is larger than the pipe diameter, it usually requires more welding work than the other flanges. So the durability is not as long as the welding neck flange, all of these factors should be considered before choose a right flange.
