Blind flange is put at the end of pipe or at the junction that would possibly be a future expansion into that direction.
Piping is easier to drill or weld at the construction stage. Once it was in use, drilling or welding will need prolong cleaning especially when the fluid transferred is combustible. For the mean of future extension, either the blind or valve would be used to seal the end.

∙ 10y agoA blind flange is a thick flange with bolt holes and no hole in the middle so it stops flow through the end of the pipe.
A blank flange is a thin plate slipped between pipe flanges in a pipeline so it stops flow through the pipe.

What are the types of flanges?
RING TYPE JOINT FLANGE The ring type joint flange metal is used for leak proof process. It is a part of steel. Sometimes the pressure becomes high at that time the ring type joint flange is using. A metal ring is compressed like a seal helps to high-pressure leak proof. THREADED RING FLANGE In threaded ring flange welding is not needed. It is threaded or screwed into another. It is used in low pressure and it can connect only with other threaded material. LAP JOINT RING FLANGE Lap joint includes a stub end or taft. The lap joint is very easy to assemble and align because it is used in low pressure only. A hub is included in a lap joint ring flange but some will not provide to reduce the cost. BLIND RING FLANGE Blind ring flanges are not connectors they are like stoppers. Blind ring flanges are blank because they are used in the end or fitting for periodical inspection only. SOCKET WELD RING FLANGE In socket weld ring flanges the bore of pipe and the flanges both are same, it helps to provide the good flow. The receiver pipe also bored because the socket weld flange and the receiver pipe should tighten. WELD NECK RING FLANGE In weld neck ring flange the boring area and the flanges must be matched to avoid problems inside the pipe. In critical applications the weld neck is durable. SLIP-ON RING FLANGE The slip-on ring flanges don't have neck, it only has a molding area to fit with the pipe. In fabricated applications, the slip-on ring flange is very easy to use. for more check jfindustries
What is a spectacle blind flange?
"A spectacle blind - also known as a figure-8 blind - is generally a piece of metal that is cut to fit between two pipe flanges and usually sandwiched between two gaskets. A spectacle blind is often made from two metal discs that are attached to each other by a small section of steel. The shape is similar to a pair of glasses or "spectacles" - hence the name spectacle blind. One end of the blind will have an opening to allow flow through the pipe during operation and the other end is solid to block flow during maintenance. They are generally installed as a permanent device to separate process piping systems."[1]The whole idea of a spectacle blind is so that one can 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 valved off and pressure relieved prior to loosening flange bolts and swinging the blind.References1.

What is the difference between 6A-6B and 6A-6BX flanges?
6A-6B flanges are ring type joint which is not developed for face to face make up, where the bolting forces act on gasket. 6A-6BX flanges are also ring type joint but it is developed with raised face hence the bolting forces act on this raised face and not on the gasket if it is properly placed. And also the raised prevent the flange damage from excessive bolting torque.

Different Types of Flanges Used in Piping Applications?
Flanges are piping equipment that is used to connect different pipes and valves. Flanges are attached to the end of a pipe, where another pipe is to be attached. Flanges are used to create a piping system, where they are used to change direction or connect two different valves or pipes.The Flange types are classified on the basis of application and grade of metal used for the production of Flange Face. Each type of flanges has a different purpose than the other. Here are various types of flanges,Types of Flanges: -1. Threaded Flanges: - The Threaded flanges have threads under their bore. They are also known as Screwed Flanges. The Thread is used to fix the pipes, which also have threading on their end. They are the easiest to fit Flanges but are not suitable for high-temperature applications. They are also not suggested for high-pressure applications.2. Slip-on Flanges: - Slip-on Flanges are made with holes that match the outer diameter of a pipe. The pipe is passed through the hole and fillet welded from both sides. Low pressure and low-temperature applications are suitable for this kind of flange joint. Slip-on flanges are generally forged and come with a hub. Large sizes are used to connect big bore pipes with storage tanks.3. Socket-Weld Flanges: -Usually used only for Low pressure and temperature applications, Socket-Weld Flanges have a female socket. A pipe is fitted through the female socket in the Flange.4. Lap-Joint Flanges: -Lap-joint flanges are made in two components, which include a stub-end and a loose backing flange. Lap-joint Flange is used for applications that require frequent dismantling. They are designed to not wear from frequent modifications.5. Blind-Flanges: - These Flanges are used as a termination point to a piping system. Blind-Flanges have a blank surface with a bolt point to fit a pipe.6. Spectacle blind flanges: Spectacle Blinds, generally referred to as SB, are Flanges that are applied to systems that require regular separation from their installation. Spectacle blinds are made from two discs, that are attached to each other. One of the discs in SB Flanges is a ring and the other is a solid plate.7. Long weld neck flanges: Long Neck Welding Flanges are made with a circular fitting and a bulging rim around the circumference. They are similar to standard Welding Neck flanges but with a particularly long neck. They are generally not used for pipes but in processing plants.8. Orifice Flange: Orifice Flanges are used to measure the flow rate of liquids or gases in the pipeline. They are used with orifice meters and are suitable for all intensive weld neck flanges with extra machining.9. The Flat-Face flange: Flat Face Flanges frequently are used where casting is used to make mating flange or flanged fitting. Similar to a bolting circle face, they have a gasket surface in the same plane.10. Ring Type Joint: The ring Type Joint flange, generally known as RTJ, is made by putting some grooves cut on their faces. They seal when the Bolts are tightened. These bolts compress the gasket into the grooves. These Flanges are typically used for high pressure and high-temperature services.11. Raised Face: The Raised Face Flanges are high-pressure flanges that have a raised face due to gasket surfaces are raised above the bolting circle face. They are widely used in process plant applications because of their increased pressure containment capability.12. Tongue & Groove: The Touch and groove Flanges consist of two flanges, where one face consists a ring machined onto the flange and the other contains a depression matching the ring on the other. These are commonly found on pump covers and Valve Bonnets.

What is a flange spreader?
A flange spreader is a device that uses a ratchet, leverage and fulcrum points to spread a bolt together connection. Usually welded pipe to flange, then a seal or gasket, and then another flange, and then welded or threaded pipe carries on. A flange spreader is used to spread the flanges apart to change a gasket or put in a spec blind to blank either side of the connection.
