Various Types of Flanges :
Blind Flanges A blind flange has no bore. It is used in applications to close the ends of piping systems, and this type of flange also allows easy access to the line once it has been sealed.Blind flanges may be machined in order to accommodate a pipe of normal size which has been reduced. The reduction can take the form of either a thread or a weld.
Weld Neck Flanges. This type of flange is drilled to a point where the wall thickness is machined to match the dimensions of the pipe. The lighter the pipe is the larger the bore must be, and visa versa. These flanges can be used for high pressure, cold or hot temperature applications.
Slip-On Flanges. A slip-on flange is one that is bored to a slightly larger size than the pipes outer diameter. The pipe then slips into the flange and is then welded inside and out in order to prevent leaks.
Orifice Flanges. The function of these Flanges is to meter the flow of either gas or liquids in the pipe. Jack screws are needed to spread the flange apart in order to change an orifice plate that is situated between two flanges.
Socket Weld Flanges are similar to slip-on flanges. The difference is that a counter bore in required which is slightly bigger than the outer diameter of the pipe which allows the pipe to be inserted
