SS 904L Flange is a primarily used to attach two components together in a joint thereby making it a complete component. SS 904L Flange provides higher strength to the join and helps to maintain their fixed position. 904L SS Flange also improves the stress capacity of joint, thereby enhancing the joint. TP 904L Flange is exclusively used for its useful characteristic of easy  process of installation and even more easy process  of dismantling without causing any harm to the original component itself, and hence easy to handle.

Two flanges are used with a pre-loaded gasket between them, which is bolted together strongly to create a flanged joint. SS904L Flanges apply the necessary mechanical force to keep the joint stable and also provides with a smooth connection to the flanged joint. SS 904L Flanges are welded or threaded as per there requirement. Stainless Steel 904L Flanges add protection and strength to the joint. Use of flanges helps in ease for disassembly and promotes ease of repair work and maintenance work.
SS 904L Flanges are available is a wide variety of styles, different pressure classes and pipe schedule. To ensure the pipe bore matches the bore of Weld Neck flange and Socket Weld Flange, it requires specifying the pipe schedule.

Types of SS 904L Flanges

COMMON FLANGES:-

SS 904L Weld Neck Flange or Welding Neck Flange
Also known as ANSI Flange, ASME B 16.5 Flange, High Hug Flange and Tapered Hub Flange. The Weld Neck Flange is usually machined from forging and is designed typically for butt weld connection to the pipe or any component which requires a flanged joint. A weld neck flange consists of circular fittings with a protruding rim with series of drilled holes around its circumference. These drilled holes serve in joining the flange with another flange with help of bolts. Welded Neck helps in providing excellent service under various temperature, pressure and stress applications. The pipe schedule for bore must be specified in Weld Neck Flange. Due to its welding neck, it’s a popular choice in various applications like pressure vessels, making man holes etc.

SS 904L Slip On Flange
These Flanges Slip over the pipes. Their inside diameter is slightly bigger then outside diameter of pipe. They are attached to the pipe by using fillet weld on the top and they bottom of the flange. They are mostly available in raise or flat face. The standard slip on flange raised face height is 1/4″ for 400 and above, whereas the standard slip on flange raised face is 1/16″ for below 400. A slip on flange is exclusively designed to slip over the end of pipe, which allows for easy positioning before welding. Slip On Flange Welding is done on both sides,  inside and outside of the pipe. The pipe is generally inserted all the way, inside the slip on flange, leaving only the gap equivalent to wall thickness of pipe. These flanges are also knows as ANSI Flange or ASME B16.5 Flange.

SS 904L Threaded Flange
Also known as Screwed Flange or Screwed On Flange. Threaded Flanges are used where welding is not an option. Threaded Flange consist of tapered internal thread i which the pipe is screwed into. Threaded pipe Flanges are only suitable for low pressure (upto 4: nominal) which do not contain any thermal cycles which could possibly cause the thread to loosen up or damage to threads.

SS 904L Lap Joint Flange
Also known as Van Stone Flange. Lap Joint Flange consists of a two components, one is stub end and another is flange itself. The stub is slipped or inserted over the pipe and welded to pipe, which helps in better alignment of position in conditions where non-alignment is an issue to be addressed. Bolt hole alignment issue is therefore eliminated in Lap Join Flanges. In Lap Joint Flange, the flange is not in direct contact with the pipe but the stub end comes in direct contact with pipe. Stub end comes in two types (Type A and Type B). Lap Joint Flange is very similar to Slip On Flange, except that lap joint flanges as round edges on the back side and has flat face. Lap joint Flanges comes only with flat face. Lap joint flange is used mostly in application requiring frequent dismantling.

SS 904L Blind Flange
In order to close an open end of the pipe or nozzle, Blind Flange is used effectively. Blind Flange does not contain any bore or hole within it. It is a solid flange used to close the end of pipe, fittings, valves, nozzles, equipments etc. Blind flange is available in both raised face and flat face. Blind Pipe Flange is mostly applicable in pressure testing equipments.

SS 904L Socket Weld Flange
Socket Weld Flanges are generally used on high pressure pipes of smaller size. Socket Weld Pipe Flanges consist of socket end with a protruding rim with series of drilled holes around its circumference. Pipe is inserted into the socket end by inserting the pipe into it. The Socket end is welded to pipe by using fillet weld around the top. This process helps in obtaining a smooth bore and ease of flow of the fluid inside the pipe. Socket Weld flanges are generally available with flat face, raised face, or RTJ facing. The standard slip on flange raised face height is 1/4″ for 400 and above, whereas the standard slip on flange raised face is 1/16″ for below 400.

SPECIAL FLANGES:-

SS 904L Orifice Flange
Orifice Flange falls in the category of Special Flanges. Orifice Flange is always used in pairs. Orifice Flange is exclusively used to measure the flow of the liquid/gas conveyed by the pipe. The flow is measured by using Flow Nozzle, which is positioned on the Orifice Flange itself. Orifice Flanges consist of pairs of pressure tapings which are machined into the orifice flange, which reduces the use of separate tapings on the pipe walls unnecessary. Orifice Flange is used in sync with orifice plate. These flanges contain tapped holes within the flange rims, which are pre-drilled and fixed to accommodate metering pipes. Orifice flange is usually made of Weld Neck Flange, where as Slip On Flange and Threaded Flange are also used at times as end connections. To sense the pressure through tapped holes, orifice flange needs to be drilled.

SS 904L Reducing Flange
Reducing Flange falls in the category of Special Flanges. Reducing Flange is generally used in cases where there is change in pipe size and applicable on projects which requires fitting together of different pipe sizes. Reducing Pipe Flange is designed to change the line size without actually adding any extra fittings. Reducing Flange consist of predominate flange which matches the larger pipe size, but has a smaller bore to match the smaller pipe size. Reducing Flange provide the most perfect solution when you need to connect different size flanges. Reducing flanges are fixed by welding, gluing or clamping flanges of equal dimensions provided with different connecting pieces. Reducing Flanges generally comes in Blind flanges, Slip on flanges, threaded flanges and weld neck flanges. They are available in various pressure classes. Reducing flanges makes an excellent alternative for connection two different pipe sizes. Reducing flange should not be used in an abrupt transition, as it would create unwanted turbulence. The reduction in a reducing flange is always abrupt compared to a reduction that can be achieved by concentric butt weld reducer. A 6″ by 4″ reducing slip on flange will have the flange dimension (outer diameter, bolt circle diameter) of a 6″ flange but the hole of a 4″ flange. This allows it to mate to an 6″ pipe via flanged connection but connect a 4″ pipe instead.

SS 904L Expander Flange
Expander Flange falls in the category of Special Flanges. Expander flange is similar to Reducing Flange, but its hub expanding to larger size. Reducing Flange consist of predominate flange which matches the smaller pipe size, but has a bigger bore to match the larger pipe size. Expander Flange is type of welding neck flange. Expander flanges is exclusively useful where the available space is limited and need to connect larger pipe size. Expander flanges are cost-effective alternative to using a separate reducer-welding neck flange combination. Expander Flange is available in a various sizes.

SS 904L Nipo FLange or SS 904L Weldo FLange
The NipoFlange or WeldoFlange falls in the category of Special Flanges.  The NipoFlange or WeldoFlange is a perfect combination of supposedly Weldolet (or Nipolet) and a Welding Neck Flange. The unique thing about it is, the 2 components mentioned before are manufactured in one piece, and not welded. On the run pipe side, a nipoflange is designed like a weldolet, which means the branch connection on the run pipe side is a welding connection and on the other side it has a flange connection. The flange connection can be designed as per the requirement of client. This Flange is primarily in Branch-connections.

SS 904L Tongue and Grove Flange
The Grove and Tongue Flange fall in the category of Special Flanges. Also known as Grove and Tongue Flange, Grove & Tongue Flange, or Tongue Flange. Grove and Tongue Flange is very similar to Slip On Flange in outline. But since the bore is Grove and Tongue, it can be assembled without welding. In order to create a seal between the pipe and Grove & Tongue flange the threads are tapered, as the taper approach the same diameter. The most unique thing and advantageous quality about Grove & Tongue flange is that they can be attached to pipe without welding. These Grove and Tongue Flange can be used to connect other Grove and Tongue Flange in low pressure, non-critical applications.

SS 904L Long Neck Flanges
Also known as LWN Flanges and falls in the category of Special Flanges. Long Weld Neck Flange is similar to Standard Weld Neck Flange, but Standard Weld Neck Flange are used for pipes whereas Long Weld Neck Flange is applicable in high pressure and high temperatures (or fluctuating) conditions, which are mostly noticed in oil and gas industry. The long neck helps in guiding the pipe into the flange, thus providing better reinforcement that a Standard Weld Neck Flange is not capable of providing. The reinforcement provided by long neck in Long Weld Neck Flange is very important for safer in high pressure commercial, industrial and residential systems. Typically, the long weld-neck flange is the anchors for water-mains or sources of gas being pumped into a larger network of pipes, such as those in a factory or in an apartment building. Long weld-neck flanges also are used in situations expansion bends or changes the pipe because of the high pressure.

SS 904L Flange Forming:

SS 904L Flange Corrosion Resistance:
904L gives good resistance to both organic and inorganic acids.The addition of copper in 904L grade gives excellent corrosion resistance against nickel stainless steels , to sulphuric, phosphoric, acetic acids, hydrochloric acids, etc. It also gives a high resistance to pitting in chloride solutions, a excellent resistance to both crevice and stress corrosion cracking.The 904L is much better  than austenitic stainless steels due to the higher alloying of nickel and molybdenum.The high percentage of  chromium content in 904L gives and maintains a passive film which protects the material in many corrosive environments.

SS 904L Flange Cold Forming:
Cold forming 904L can be done easily. The composition of molybdenum and nitrogen implies more powerful processing equipment may be needed.Most of the time more common methods like cooling with air or water, etc is used.

SS 904L Flange Hot Forming:
Hot and heat forming should be done after uniform heating.Complete annealing should be done before any hot forming in order to retain maximum ductility and corrosion resistance property. It is very important that the whole process should be done above 1100°C.

SS 904L Flange Machining:
The machining of  904L  requires  proper care to achieve the expected result. The cutting speed should be slow and proper care should be taken while doing so.

SS 904L Flange Welding:
The 904L material should be allowed to cool in between, preferably to below 150°C temperatures. To obtain good welding properties welded condition, filler material shall be used.Because of high thermal expansion, welding must be carefully planned in advance to ensure that distortion of the welded joint can be kept under control.

SS 904L Flange Heat Treatement:
The heat treatment should be accompanied by cooling in water or air immediately. This treatment should be applied for both solution annealing and stress relieving from the 904L material.
