What is difference between weld neck flange and slip on weld flange?

http://www.tubecraftflange.com/products/slipon.htmTubeSlip-On Flanges are probably the most common type of flanges in the industry and are ideal for lower pressure applications. You do not have to specify the pipe schedule when using slip-on flanges due to the fact that its inside diameter is determined by the outside diameter of the pipe. This outside diameter of the pipe does not change for the different schedules. This often makes these easier to stock for vendors. Fabricators also like the fact that these flanges are slightly easier to align than weld neck flanges. They also are slightly easier to cut pipe to the proper length for. They can be used for high temperature and pressure applications but are not generally recommended as compared to other types of flanges. ASME B16.5 Code limits their usage in the 1500#-2500# (lbs.) weight classes.

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


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 instrument flange?

Instrument flanges, (sometimes called Bleed Rings or Sampling flanges), allow a means to measure pressure or obtain fluid samples from a pressurized flange connected line. The instrument flange provides a means of having threaded ports in the line without drilling and tapping the principle equipment in the line (The operator can replace the instrument flange if the threaded ports should become damaged or begin to leak). Instrument flanges commonly have 2, 3, or 4 ports. The two common forms of instrument flanges, the drilled through type, and the double studded type, function interchangeability.

What is Difference Between FF & RF Flanges?

Flanges are an integral part of the Piping industry. These Flanges are used to form a link between two different Pipes. Flat (FF), elevated (RF), ring joint (RTJ), lap joint (M&F), tongue, and groove (T&G) are the 6 styles of flange faces needed. Multi-faced flanges need different gaskets and should never be matted to avoid joint leakage. The flanges RF and FF may have various finishing forms (i.e. roughness at the top of the surface): flat, lined, and serrated. Although flanges themselves have specific pound scores that reflect the levels of pressure and temperature to which they can operate, the individual flange faces vary depending on the context within which they are to be used.Various types of flange faces are used to seat the sealing gasket content as the contact surfaces. The faces are panels which matt with flanges, funnels or valves. Flange faces must be smooth enough to ensure that the flanges are fastened together to maintain a stable, leak-free seal. For this article, we must concentrate on three common types of flange faces; flat faces raised faces, and ring-style joints.Flat Face Flanges (FF)The flat-facing flange has a gasket surface in the same plane as the face of the bolt frame. Goods using flat face flanges are often those in which mold is used to make the matching flange or flanged cover. Flat face flanges should never be placed on an inverted side flange. ASME B31.1 notes that the raised face on the carbon steel flange must be removed while attaching flat face cast iron flanges to carbon steel flanges and that a full face gasket is needed. This is to prevent the small, brittle cast iron flange from splashing into the void created by the carbon steel flange’s raised nose.This type of flange face is used to make equipment and valves for all applications where Cast Iron is used for making. Cast Iron is brittle and is commonly used only in applications with low temperature, low pressure. The flat surface allows full contact of the two flanges across the entire face. Flat face flanges (FF) have a touch surface that is equivalent in height to the bolting thread of the flange. Full face gaskets are used between two flat side flanges, typically of the soft kind. According to ASME B31.3, as the resultant flanges joint will possibly leak, a flat face flange should never be matted with an elevated face flange.Raised Face Flanges (RF)The Raised Face Flange is the most common type used in process plant applications, and can be easily identified. It is referred to as a face raised because the surfaces of the gasket are positioned above the face of the bolting circle. Each style of mask requires a large range of gasket styles to be used, including varieties of flat ring sheets and metallic composites such as spiral-wrapped and double jacket forms.An RF flange aims to focus further pressure on a smaller area of the gasket and thus improve the joint’s pressure control capacity. Diameter and height, by pressure class and diameter, are described in ASME B16.5. Flange pressure level specifies the height of the face that is lifted. An RF flange aims to concentrate more pressure on a smaller area of the gasket, thereby increasing the joint’s pressure containment capacity. Diameter and height, by pressure class and diameter, are described in ASME B16.5. Pressure flange rating.
