Flange
TYPES & APPLICATIONS
These pipe flanges attach by welding the pipe to the neck of the flange. This transfers stress from the flange to the pipe instead. It also reduces the stress concentration from the base of the hub. Weld neck flanges are often used for applications where high pressure is a factor. The inside diameter of the flange is designed to match the pipe’s inside diameter. Weld Neck Pipe flanges with a hub have published specifications that range from 1/2″ thru 96″. Our company provides these in all material grades, specifications and sizes.
Weld neck pipe flanges are typically provided with a raised face, flat face, or RTJ facing. When a raised face is necessary for weld neck pipe flanges, the standard height is 1/16″ for weld neck pipe flanges under 400#. For weld neck pipe flanges of 400# and up, the standard weld neck pipe flange raised face height is 1/4″.

As made obvious by their name, these pipe flanges slip over the pipe. They’re manufactured with an inside diameter that is slightly bigger than the pipe’s outside diameter. These attachments are connected to the pipe via fillet weld at the top and bottom of the flange.
Slip on pipe flanges are typically provided with a raised or flat face. When a raised face is necessary for slip on pipe flanges, the standard height is 1/16″ for slip on pipe flanges under 400#. For slip on pipe flanges of 400# and up, the standard slip on pipe flange raised face height is 1/4″.

EEC also has many different slip on pipe flanges in stock and ready to ship. Slip on pipe flanges in stock include AWWA slip on pipe flanges, ANSI slip on pipe flanges, Pressure Vessel slip on pipe flanges and slip on pipe flanges that match the OD and drilling of ASME flanges
Socket-weld pipe flanges are typically used on smaller sizes of high pressure pipes. These pipe flanges are attached by inserting the pipe into the socket end and applying fillet weld around the top. This allows for a smooth bore and better flow of the fluid or gas inside of the pipe. Slip on Pipe flanges with a hub have published specifications that range from 1/2″ thru 24″. EEC provides Socket Weld pipe flanges in all material grades, specifications and sizes.
Socket Weld pipe flanges are typically provided with a raised face, flat face, or RTJ facing. When a raised face is necessary for socket weld pipe flanges, the standard height is 1/16″ for socket weld pipe flanges under 400#. For socket weld pipe flanges of 400# and up, the standard socket weld pipe flange raised face height is 1/4″.
EEC Supply socket weld pipe flanges in all steel material grades, including carbon socket weld pipe flanges, stainless steel socket weld pipe flanges and alloy socket weld pipe flanges. EEC also has many different socket weld pipe flanges in stock and ready to ship.
Lap joint pipe flanges slide directly over the pipe and are most commonly used with stub end fittings. A pipe is usually welded to the Stub End and the Lap Joint pipe flange is free to rotate around the stub end. The benefit of this is that there will not be any issues with bolt hole alignment. Lap Joint pipe flanges are often used for applications that require frequent dismantling.
EEC Supply lap joint pipe flanges in all steel material grades, including carbon lap joint pipe flanges, stainless steel lap joint pipe flanges and alloy lap joint pipe flanges. EEC also has many different lap joint pipe flanges in stock and ready to ship. EEC can also supply custom pipe flanges according to customer specifications.
Threaded pipe flanges are similar to slip-on pipe flanges except the bore of threaded pipe flange has tapered threads. Threaded pipe flanges are used with pipes that have external threads. The benefit of these pipe flanges is that it can be attached without welding. Threaded pipe flanges are often used for small diameter, high pressure requirements. Slip on Pipe flanges with a hub have published specifications that range from 1/2″ thru 24″. EEC provides Slip-On pipe flanges in all material grades, specifications and sizes.
Threaded pipe flanges are typically provided with a raised face, flat face, or RTJ facing. When a raised face is necessary for threaded pipe flanges, the standard height is 1/16″ for threaded pipe flanges under 400#. For threaded pipe flanges of 400# and up, the standard threaded pipe flange raised face height is 1/4″.
EEC Supply threaded pipe flanges in all steel material grades, including carbon threaded pipe flanges, stainless steel threaded pipe flanges and alloy threaded pipe flanges.EEC also has many different threaded pipe flanges in stock and ready to ship.
These pipe flanges are used to seal the end of piping systems or pressure vessel openings. They are commonly used for testing the flow of gas or liquid through a pipe or vessel. Blind pipe flanges also allow for easy access to the pipe in case work must be done inside the line. They are oftentimes used for high pressure applications. Slip on Pipe flanges with a hub have published specifications that range from 1/2″ thru 96″. We provide these types of flanges in all material grades, specifications and sizes.
Blind pipe flanges are typically provided with a raised face, flat face, or RTJ facing. When a raised face is necessary for blind pipe flanges, the standard height is 1/16″ for blind pipe flanges under 400#. For blind pipe flanges of 400# and up, the standard blind pipe flange raised face height is 1/4″.
EEC Supply blind pipe flanges in all steel material grades, including carbon blind pipe flanges, stainless steel blind pipe flanges and alloy blind pipe flanges. EEC also has many different blind pipe flanges in stock and ready to ship. Blind pipe flanges in stock include ANSI B16.5 blind pipe flanges, ASME B16.47 Series “A” blind pipe flanges, ASME B16.47 Series “B” blind pipe flanges and Pressure Vessel weld neck pipe flanges. EEC Can Supply custom weld neck pipe flanges per customer requirements.
Spectacle blinds, alternatively known as spectacle flanges and figure-8 blinds, offer a temporary or permanent means of isolating or bypassing sections of pipelines or vessels. They comprise two metal discs connected by a handle, resembling a pair of spectacles. While one disc is solid, the other features a hole or opening, enabling flow through the system when aligned with the pipe or vessel. EEC can Supply Wide Range Of Spectacle blinds Flange with Different size , material and design As Client Needs
Various special flange types exist, these
include the reducer, expander, long welding
neck, Orifice Flange, nipoflange, weldoflange, AWWA Flange
and swivel flange designs
Raised Face (RF)
- These flanges feature a small raised section around the bore with an inside bore circle gasket.
Raised Face height
- These flanges feature a height raised section around the bore with an inside bore circle gasket.
Flat Face (FF)
- As the name suggests, flat face flanges feature a flat, even surface combined with a full face gasket that contacts most of the flange surface.
Ring-Type Joint (RTJ)
- Used in high-pressure and high-temperature processes, this face type features a groove in which a metal gasket sits to maintain the seal.
Tongue-and-Groove (T&G)
- These flanges feature matching grooves and raised sections. This aids in installation as the design helps the flanges to self-align and provides a reservoir for gasket adhesive.
Male-and-Female (M&F)
- Similar to tongue and groove flanges, these flanges use a matching pair of grooves and raised sections to secure the gasket. However, unlike tongue and groove flanges, these retain the gasket on the female face, providing more accurate placement and increased gasket material options.
