• 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.

Established in 1989, HEBEI XINFENG HIGH PRESSURE FLANGE AND PIPE FITTING CO., LTD (XINFENG) specializes in the manufacture of flanges, butt weld pipe fittings in standard as well as special parts and forgings according to customer drawings.Located in Mengcun Hui Nationality Autonomous Region, known as the base for manufacture of elbows and pipe fittings in China, XINFENG enjoys a pleasant environment and convenient transportation, with Beijing and Tianjin city to the north and the Bohai Sea to the east.
