Most Selling Flanges in the World & How to Select the Best Flanges in Qatar
Flanges are essential components in pipeline systems, used to connect pipes, valves, pumps, and other equipment. They provide strength, durability, and leak-proof connections, making them crucial in industries such as oil & gas, construction, water treatment, and power plants.
Most Selling Flanges in the World
The demand for flanges varies across industries, but some types are more commonly used worldwide due to their versatility and reliability. Here are the most widely sold flanges globally:
1. Weld Neck Flanges (WN Flanges)
. Most Used In: High-pressure applications, oil & gas, petrochemical plants
. Features:
. Long, tapered hub for smooth stress distribution
. Ideal for extreme temperature and pressure conditions
. Provides excellent leak prevention
2. Slip-On Flanges (SO Flanges)
. Most Used In: Low-pressure systems, HVAC, plumbing
. Features:
. Easy to install and align
. Requires fillet welding on both sides
. More affordable than weld neck flanges
3. Blind Flanges (BL Flanges)
. Most Used In: Pipeline terminations, pressure vessel systems
. Features:
. Solid flange used to close off a pipeline
. Allows easy access for maintenance and modifications
. Withstands high-pressure conditions
4. Threaded Flanges (TH Flanges)
. Most Used In: Small-diameter piping, plumbing, low-pressure applications
. Features:
. No welding required (ideal for flammable applications)
. Easy to install and remove
. Suitable for environments where welding is not practical
5. Socket Weld Flanges (SW Flanges)
. Most Used In: High-pressure piping, chemical processing
. Features:
. Provides strong and leak-proof connections
. Fillet welded for enhanced durability
. Common in small-diameter, high-pressure pipelines
6. Lap Joint Flanges (LJ Flanges)
. Most Used In: Piping systems requiring frequent dismantling
. Features:
. Works with a stub-end fitting
. Reduces material costs (only the stub end needs to match the pipe material)
. Allows easy alignment and rotation of bolt holes
7. Orifice Flanges
. Most Used In: Flow measurement and control systems
. Features:
. Contains holes for pressure measurement
. Often used with orifice meters in oil & gas and chemical plants
. Ensures accurate fluid flow monitoring
