Weld Neck Flanges are a very common type of pipe flanges used in various industrial applications. They have a long tapered hub and are often used for high pressure applications.

Materials used:

• Steel
• Stainless Steels
• Cast Iron
• Brass
• Galvanized steel
• Carbon Steel
• Aluminum
• Copper
• Polypropylene
• PVC etc.

Key Features:

• This is the most common type of high pressure pipe flange.
• They are distinguished from other types of pipe flanges by their long tapered hub and gentle transition of thickness in the region of the butt weld joining them to the pipe.
• The long tapered hub provides an important reinforcement of the weld neck flange proper in terms of strength and resistance to dishing.

Uses of weld neck flanges:

• The weld neck flange is very resistant to dishing and has a very sturdy connection because it has the pipe along with the tapered hub.
• The flanges are ideal for extreme fluctuations of temperature.
• They are ideal in environments where there may be a lot of bending and handling of the flanges.
• Preferred in an environment with extreme temperature conditions.
• This type of flange is preferred for every severe service condition—resulting from high pressure or from sub-zero or elevated temperature.
• They are used in situations where loading conditions are substantially constant or fluctuate between wide limits.
• This is probably the best welding flange available because of its high, heavy neck.
• Highly recommended wherever a sound welded joint connection is needed.

Reducing flanges are designed for use in changing diameters in a piping system. A reducing flange comprises a flange with one specified diameter having a bore of a different and smaller, diameter. Except for the bore and hub dimensions, the reducing flange will have dimensions of the larger pipe size. These flanges are used at the outlet side of the expansion joint to increase the size of the flange. This is considered to be an economical method to make a transition in size.

Materials used:

• Carbon steel
• Stainless steel
• Alloy steel
• Brass
• Cast Iron
• Bronze
• Aluminum
• PVC etc.

Types of Reducing Flanges:

Reducing flanges are normally provided as one of the following three types:

• Welding Neck
• Slip-On
• Threaded etc.

How to connect reducing flange?

To connect two sized pipes, the appropriate reducing flange is inserted between the two and bolted into place.

Uses of Reducing Flanges:

• Reducing flanges are used in pipe-to-pipe connections.
• Reducing flanges are a little easier to bolt up than non-reducing flanges.
• They provide the most perfect solution when you need to connect different size flanges.
• These flanges are available in all types and pressures.
• Reducing flanges are fixed by welding, gluing or clamping flanges of equal dimensions provided with different connecting pieces.
• They offer the simplest and least expensive method of mating two different sized flanges.

Orifice flanges are used instead of the standard pipe flanges when orifice plate or flow nozzle is used. In other words, orifice flanges are used with orifice meters. The basic purpose for this is to measuring the flow rate of either gases or liquids in the respective pipeline. These flanges are used in various industrial applications and are available in various sizes and materials. All orifice flange units are supplied with the plate, pressure connection holes, and jack screws.

Materials used:

• Aluminum
• Brass
• Bronze
• Cast iron
• Stainless Steel
• Carbon Steel
• Alloy
• Nickel
• Copper etc.

Key Features:

• Come with either raised faces or ring type joint (RTJ) facings.
• The orifice flanges have modifications of radial tapped holes in the flange ring for meter connections. Need A Reliable Fitting?
• There are the orifice plate carriers in these flanges for the reason of fitting meter connections.
• The additional bolts available serve as a jack to allow the separation of the two flanges to change the orifice plate or for other relevant services like inspection.

Uses of orifice flanges:

• The basic purpose of an orifice flange is used to flow/rate metering of piping systems.
• They are used for all intensive purposes, similar to weld neck and slip-on flanges with extra machining.
