Key Features:
Can be attached to the pipe without welding (sometimes an additional seal weld is used as well) Ideal for higher pressure and temperature applications for small pipe sizes. Not recommended for larger loads, especially when subjected to higher torque.

Similar to Slip-on flange, a socket-weld flange however has a recession machined into the hub side of the flange with width equal to the thickness of the pipe. Usually developed for small sizes, these socket-weld flanges are beneficial for pressure applications. Socket Weld Flange is welded to a pipe with one fillet weld over the socket with no primary alignment practice required.
The passive Strength of the socket-weld flange is 2/3rd that of weld neck and fatigue strength is equal to slip-on flange.While welding the pipe to the socket-weld flange one must mind a clearance gap between the pipe and the seat of the recession in order to reduce the residual stress at the root of the weld. The space between the pipe and the seat however allows settlement of the fluid and induces erosion and corrosion at the gap which is a major disadvantage of using a socket-weld flange.

Lap Joint Flanges(Loose Flanges) are used with a corresponding stub-end that "inserts" in the inside of the flange. The main benefit of this type of flange, is that once the pipe welds to the insert stub-end, the flange then can rotate for easier alignment of the bolting holes. However, lap joint flanges and their stub-ends' ability to hold pressure is about the same as slip-on flanges. They are not suitable for situations with a high external or changing loads of force. They do provide an advantage in a piping system that needs frequent dismantling for inspection or to remove build-up

Manufacturing
Lap Joint Plate Flange can be manufactured as forged or directly machined from plates. Whereas Stub has to be manufactured as wrought from parent Pipe, seamless or welded by cold press or hot press method.

Applications
lap Joint Flanges are preferred for low cost pipeline projects specially civil water pipeline projects, Chemical Processing, Paint & Food Processing units & some sector of Oil & Gas pipelines.

We expertise in manufacturing and offering wide variety of socket welding flanges. Highly durable and reliable, these socket welding flanges results in smooth & flawless performance. All the products are widely appreciated by our clients and are available at highly competitive prices. Custom designing of products is done as per the specifications of the clients.

Designed for reliable performance, our range of PN flanges are available in various sizes and results in long lasting performance. Manufactured with utmost care and as per the standard technical specifications, these PN flanges are available at the most competitive prices.

The flange is slipped over the pipe and then welded both inside and outside to provide sufficient Strength and prevent leakage. This flange is used in preference to weld necks by many users because of its lower cost and the fact that less accuracy is required when cutting pipe to length.

The Flat Face (FF) flange has a gasket surface in the sameplane as the bolting circle face. Applications using flat face flanges are frequently those in which the mating flange or flanged fitting is made from a casting.

Flat face flanges are never to be bolted to a raised face flange. ASME B31.1 says that when connecting flat face cast iron flanges to carbon steel flanges, the raised face on the carbon steel flange must be removed, and that a full face gasket is required. This is to keep the thin, bittle cast iron flange from being sprung into the gap caused by the raised face of the carbon steel flange.

Owing to our rich industrial experience, we are offering a comprehensive range of Long Weld Neck Flanges. The professionals of our organization source these neck flanges from trusted vendors. These flanges are unique due to their simple connectivity with other pipes. Moreover, our products are extensively used in refining industries for linking purposes. Our esteemed patrons can avail these qualitative range of flanges from us at industry-leading prices.

The Groove and Tongue faces of this flanges must be matched. One flange face has a raised ring (Tongue) machined onto the flange face while the mating flange has a matching depression (Groove) machined into it's face.Tongue-and-groove facings are standardized in both large and small types. They differ from male-and-female in that the inside diameters of the tongue-and-groove do not extend into the flange base, thus retaining the gasket on its inner and outer diameter. These are commonly found on pump covers and Valve Bonnets.Tongue-and-groove joints also have an advantage in that they are self-aligning and act as a reservoir for the adhesive. The scarf joint keeps the axis of loading in line with the joint and does not require a major machining operation.

General flange faces such as the RTJ, T&G and the F&M shall never be bolted together. The reason for this is that the contact surfaces do not match and there is no gasket that has one type on one side and another type on the other side.

The function of an orifice flange is to provide access to a line for metering of gases or liquids. An orifice plate is clamped between a pair of flanges when installed in a line and the whole assembly is refer to as an orifice flange union. Jack-screws within the assembly facilitate removal of the orifice plate. The orifice plate, the metering device, consists of a thin plate with a concentric, square edge, circular hole in the centre. Two pressure tap-holes are drilled in each flange to measure pressure difference through the orifice.

This is again similar to a slip-on flange, but it has a radius at the intersection of the bore and the flange face toaccommodate a lap stub end. The face on the stub end forms the gasket face on the flange. This type of flange is used in applications where section of piping systems need to be dismantle quickly and easily for inspection or replacement.

This is a pressure retaining plate with one solid end and one open end connected with a web or tie-bar. In normal operation, the open end forms the seal between two flanges and permits normal flow of fluid through pipe work. If the solid end is swung into position it effectively blanks of the pipe and halts the flow.

This is similar to a slip-on flange in outline, but the bore is counter-bored to accept pipe. The diameter of the remaining bore is the same as the inside diameter of the pipe. The flange is attached to the pipe by a fillet weld around the hub of the flange. An optional interval weld may be applied in high stress applications. Its biggest use is in high pressure systems such as hydraulic and steam lines.

This is similar to a slip-on flange in outline, but the bore is threaded, thus enabling assembly without welding. This obviously limits its application to relatively low pressure piping systems. The flange may be welded around the joint after assembly, but this is not considered a satisfactory method of increasing its applications.

The Raised Face (RF) type is the most applied flange face, and is easily to identify. It is referred to as a raised face because the gasket surfaces are raised above the bolting circle face.

Key Features:
Can be attached to the pipe without welding (sometimes an additional seal weld is used as well) Ideal for higher pressure and temperature applications for small pipe sizes. Not recommended for larger loads, especially when subjected to higher torque.

Similar to Slip-on flange, a socket-weld flange however has a recession machined into the hub side of the flange with width equal to the thickness of the pipe. Usually developed for small sizes, these socket-weld flanges are beneficial for pressure applications. Socket Weld Flange is welded to a pipe with one fillet weld over the socket with no primary alignment practice required.
The passive Strength of the socket-weld flange is 2/3rd that of weld neck and fatigue strength is equal to slip-on flange.While welding the pipe to the socket-weld flange one must mind a clearance gap between the pipe and the seat of the recession in order to reduce the residual stress at the root of the weld. The space between the pipe and the seat however allows settlement of the fluid and induces erosion and corrosion at the gap which is a major disadvantage of using a socket-weld flange.

Lap Joint Flanges(Loose Flanges) are used with a corresponding stub-end that "inserts" in the inside of the flange. The main benefit of this type of flange, is that once the pipe welds to the insert stub-end, the flange then can rotate for easier alignment of the bolting holes. However, lap joint flanges and their stub-ends' ability to hold pressure is about the same as slip-on flanges. They are not suitable for situations with a high external or changing loads of force. They do provide an advantage in a piping system that needs frequent dismantling for inspection or to remove build-up

Manufacturing
Lap Joint Plate Flange can be manufactured as forged or directly machined from plates. Whereas Stub has to be manufactured as wrought from parent Pipe, seamless or welded by cold press or hot press method.

Applications
lap Joint Flanges are preferred for low cost pipeline projects specially civil water pipeline projects, Chemical Processing, Paint & Food Processing units & some sector of Oil & Gas pipelines.

The flange is slipped over the pipe and then welded both inside and outside to provide sufficient Strength and prevent leakage. This flange is used in preference to weld necks by many users because of its lower cost and the fact that less accuracy is required when cutting pipe to length.

The Flat Face (FF) flange has a gasket surface in the sameplane as the bolting circle face. Applications using flat face flanges are frequently those in which the mating flange or flanged fitting is made from a casting.

Flat face flanges are never to be bolted to a raised face flange. ASME B31.1 says that when connecting flat face cast iron flanges to carbon steel flanges, the raised face on the carbon steel flange must be removed, and that a full face gasket is required. This is to keep the thin, bittle cast iron flange from being sprung into the gap caused by the raised face of the carbon steel flange.

Owing to our rich industrial experience, we are offering a comprehensive range of Long Weld Neck Flanges. The professionals of our organization source these neck flanges from trusted vendors. These flanges are unique due to their simple connectivity with other pipes. Moreover, our products are extensively used in refining industries for linking purposes. Our esteemed patrons can avail these qualitative range of flanges from us at industry-leading prices.

The Groove and Tongue faces of this flanges must be matched. One flange face has a raised ring (Tongue) machined onto the flange face while the mating flange has a matching depression (Groove) machined into it's face.Tongue-and-groove facings are standardized in both large and small types. They differ from male-and-female in that the inside diameters of the tongue-and-groove do not extend into the flange base, thus retaining the gasket on its inner and outer diameter. These are commonly found on pump covers and Valve Bonnets.Tongue-and-groove joints also have an advantage in that they are self-aligning and act as a reservoir for the adhesive. The scarf joint keeps the axis of loading in line with the joint and does not require a major machining operation.

General flange faces such as the RTJ, T&G and the F&M shall never be bolted together. The reason for this is that the contact surfaces do not match and there is no gasket that has one type on one side and another type on the other side.

The function of an orifice flange is to provide access to a line for metering of gases or liquids. An orifice plate is clamped between a pair of flanges when installed in a line and the whole assembly is refer to as an orifice flange union. Jack-screws within the assembly facilitate removal of the orifice plate. The orifice plate, the metering device, consists of a thin plate with a concentric, square edge, circular hole in the centre. Two pressure tap-holes are drilled in each flange to measure pressure difference through the orifice.

This is again similar to a slip-on flange, but it has a radius at the intersection of the bore and the flange face toaccommodate a lap stub end. The face on the stub end forms the gasket face on the flange. This type of flange is used in applications where section of piping systems need to be dismantle quickly and easily for inspection or replacement.

This is a pressure retaining plate with one solid end and one open end connected with a web or tie-bar. In normal operation, the open end forms the seal between two flanges and permits normal flow of fluid through pipe work. If the solid end is swung into position it effectively blanks of the pipe and halts the flow.

This is similar to a slip-on flange in outline, but the bore is counter-bored to accept pipe. The diameter of the remaining bore is the same as the inside diameter of the pipe. The flange is attached to the pipe by a fillet weld around the hub of the flange. An optional interval weld may be applied in high stress applications. Its biggest use is in high pressure systems such as hydraulic and steam lines.

This is similar to a slip-on flange in outline, but the bore is threaded, thus enabling assembly without welding. This obviously limits its application to relatively low pressure piping systems. The flange may be welded around the joint after assembly, but this is not considered a satisfactory method of increasing its applications.

The Raised Face (RF) type is the most applied flange face, and is easily to identify. It is referred to as a raised face because the gasket surfaces are raised above the bolting circle face.
