FLANGE

Flange

A flange is a critical component used to connect pipes, valves, pumps, and other equipment to form a secure, leak-proof piping system. It provides a reliable mechanical joint that allows easy assembly, disassembly, and maintenance of pipeline sections.

Key Functions

• Connection Interface
  Flanges join two components together, enabling fluid flow continuity while maintaining system integrity.

• Ease of Maintenance
  Facilitates quick disassembly for inspection, cleaning, or repair without cutting the pipe.

• Seal Surface
  Works with gaskets to ensure a tight, leak-free seal between connected parts.

Common Types

• Weld Neck Flange: Provides strong connection by welding to the pipe; suitable for high-pressure applications.

• Slip-On Flange: Slides over the pipe for simpler installation; used in low-pressure systems.

• Blind Flange: Used to close the end of a pipe or vessel.

• Socket Weld Flange: Pipe is inserted into the flange and welded; ideal for small diameter, high-pressure systems.

• Threaded Flange: Screwed onto pipes without welding; used for low-pressure and non-critical applications.

• Lug Flange: Features threaded inserts for bolting; allows single-sided removal of piping sections.

Material & Standards

• Commonly made from carbon steel, stainless steel, alloy steel, or other metals depending on application requirements.

• Manufactured according to standards like ANSI/ASME, DIN, EN, and JIS to ensure compatibility and safety.

Applications

Flanges are widely used across industries including oil & gas, petrochemical, water treatment, power generation, and manufacturing, providing essential connectivity in piping and valve systems.
