• Types of Flanges -

• Our manufacturing facilities is well equipped to manufacture various types of flanges namely:

• Blind Flange-
• A Blind flange is round plate which has all of the relevant boltholes but no centre hole,
• Because of this feature this flange is used to close off the ends of a piping systems and pressure vessel openings.
• It also permits easy access to vessels or Piping systems for inspection purposes.
• Weld Neck Flange-
• Weld Neck Flanges have a long tapered hub and are often used for high pressure applications.
• These flanges are designed to be joined to a Piping system by Bun Welding. The Neck, or Hub,
• transmits stresses to the Pipe, reducing stress concentrations at the base of the Flange.
• The gradual transition of thickness from the base of the Hub to the wall thickness at the Bun Weld,
• provides important reinforcement of the Flange. The bore of the Flange matches the bore of the Pipe,
• reducing turbulence and erosion. These flanges are ideal for extreme fluctuations of temperature
• and in environments where there may be high pressure or high temperature being dealt with.
• Slip-on Flange-
• These are easily fitted and welded into different pipes. Slip on pipe flange is slipped over the Pipe and
• then welded both inside and outside to provide sufficient strength and prevent leakage.
• These flanges are ideal for lower pressure applications. 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.
• Socket Weld Flange-
• These flanges are attached by inserting the pipe into the socket end. This allows for a smooth bore and better
• flow of the fluid or gas inside of the pipe. Socket-weld pipe flanges are mainly used for smaller sizes of high
• pressure pipes.
• Threaded Flange-
• Threaded flanges are similar to slip-on pipe flanges except the bore of threaded pipe flange has tapered threads.
• These flanges are ideal for relatively low pressure piping systems. Threaded flanges are used with pipes that have
• external threads. The benefit of these pipe flanges is that it can be attached without welding.
• Lap Joint Flange-
• Lap Joint Flanges slide over the pipe and are most commonly used with Stub End Fittings. A pipe is typically welded
• to the Stub End and the Lap Joint pipe flange is free to rotate around the stub end. Lap Joint pipe flanges are often
• used for applications that require frequent dismantling. Threaded pipe flanges are often used for small diameter,
• high pressure requirements.
