Weld Neck Flange
A Weld Neck Flange is drilled with the wall thickness of the Flange having equal dimensions to the matching pipe. The lighter the pipe is the larger the bore is in the Weld Neck Flange. And conversely the heavier the pipe is the smaller the bore is in the Weld Neck Flange. Weld Neck Flanges are usually used in high pressure systems and are suitable for cold or hot temperatures.
Blind Flange
A Blind Flange is a Flange which has no bore hole and consequently it is used to close the end of a piping system. The Blind Flange is sometimes machined to accept a pipe of the nominal size to which reduction is being made. The Blind Flange reduction can be either threaded or welded. A Blind Flange also allows easy access to a line once it has been sealed.
Socket Weld Flange
A Socket Weld Flange is similar to a Slip On Flange, however Socket Weld Flanges have an internal recess on the inside diameter to allow for a smoother flow of the process fluid.
This creates a smooth bore with the proper welding and grinding. However a Socket Weld Flange can be more expensive than a Slip On Flange due to the more intricate machining. Socket Weld Flanges were initially developed for use on smaller sizes of pipe at higher pressure ratings.
Spectacle Blind Flange
A Spectacle Blind Flange allows you to be absolutely sure that an item of equipment is properly and securely blanked off with no possibility of any flow or leakage through a valve during maintenance.
The flow can be diverted to other items of equipment but not just bypassed around the blank as this would compromise the safety function of the Spectacle Blind. The flow has to valve off and pressure relieved prior to loosening Flange bolts and swinging the blind.
