A Blind Flange is a solid disk used to block off a pipeline or to create a stop. The blind flange is machined in the same manner as a regular flange with the mounting holes around the perimeter and the gasket sealing rings machined into the mating surface. The difference is that a blind flange has no opening to allow fluid to pass through. The blind flange can be inserted between two open flanges and used to block off the flow of liquid through a pipeline. Without the blind flange it would be difficult to perform maintenance or repairs on a pipeline. The flow would need to be shut off at the nearest valve, which could be miles away from the repair area. Valves are also very expensive and are prone to sticking. The blind flange is a much more cost efficient way of sealing a pipe.

The Weld Neck Flange is normally referred to as the "high hub" flange. It is designed to transfer stresses to the pipe, thereby reducing high stress concentrations at the base of the flange. The Weld Neck flange is the best-designed butt-welded flange of those currently available because of its inherent structural value. It is expensive because of the design. These are mainly used on heat coupling of pipes when there is possibility of expansion of the section while bending stress on the coupling.

The Threaded Flange is similar to the slip-on flange, but the bore is threaded. Its chief merit is that it can be assembled without welding, explaining its use in low pressure services at ordinary atmospheric temperatures and in highly explosive areas where welding create a hazard. These flanges are used in special requirements to work under high temperature and pressure, making sure no welding joint is made at the assembly.
