Types of Large Diameter Flanges

Large diameter industrial flanges are specialized components used to connect, seal, and reinforce piping systems, particularly in large-scale industrial applications. These flanges are designed for use with pipes of significant diameters, often exceeding 24 inches (600 mm), and are critical for handling high pressures, temperatures, and volumes of fluids or gases.

Weld Neck Flanges

• Ideal for high-pressure applications.
• Welded to the pipe, providing strength and reducing stress concentration.

Slip-On Flanges

• Slide over the pipe and are welded at both the inside and outside.
• Suitable for low-pressure applications.

Blind Flanges

• Solid disks used to close off a piping system or vessel.
• Often used for pressure testing.

Lap Joint Flanges

• Used with stub end fittings for systems requiring frequent dismantling.
  Not welded directly to the pipe.

Threaded Flanges:

• Used for smaller diameter pipes and systems where welding is not feasible.

Socket Weld Flanges

• Used in smaller high-pressure systems, with the pipe inserted into the flange and welded around the hub.

Ring Type Joint (RTJ) flanges

• Are used to create a leak-free seal between pipes in high-pressure and high-temperature applications.

Materials Used

• Carbon Steel: For general industrial use and low-corrosive environments.
• Stainless Steel: For corrosion resistance in chemical and food industries.
• Alloy Steel: For high-temperature and high-pressure applications.
• Duplex Steel: For enhanced strength and corrosion resistance.

Key Benefits of Large Diameter Flanges

• Leak Prevention: Strong sealing capabilities for high-pressure systems.
• Structural Integrity: Provides strength and support for large piping networks.
• Ease of Maintenance: Simplifies disassembly and reassembly during maintenance.
• Versatility: Suitable for a wide range of industries and fluid types.
