What Are Steel Pipe Flanges?
Steel pipe flanges are flat, circular components that connect pipes to valves, pumps, or other equipment. They may be welded or threaded onto pipe ends and then bolted together to create a sealed joint.
- Modularity – Easily dismantle piping for cleaning, inspection, or repairs.
- High Strength – When paired with the right gaskets and torque, they withstand high pressure and temperature.
- Versatility – Manufactured to ANSI/ASME, API, and DIN standards in carbon steel, stainless steel, and alloy materials.
- Multiple Types – Including weld-neck, slip-on, blind, threaded, lap-joint, and socket-weld options tailored to specific needs.
Steel pipe flanges in Manassas, VA, are used everywhere—from water plant improvements along Godwin Drive and stormwater upgrades near Wellington Road to HVAC projects in Prince William County Public Schools and industrial sites near Innovation Park.
Frequent Applications of Steel Pipe Flanges in Manassas
- Water Treatment & Public Utilities: City utility projects often use flange connections to streamline maintenance of water mains, sewer systems, and pumping stations.
- Industrial & Manufacturing Facilities: Local manufacturers and logistics hubs rely on flanged piping for steam, compressed air, chemical transfer, and process lines.
- Commercial HVAC Systems: Office buildings, medical centers, and schools use flanges to connect chillers, boilers, and air handlers—allowing quick access without full shutdowns.
- Pump Skids & Equipment Hookups: Prefabricated pump skids and mechanical rooms use flanges for fast installation, secure alignment, and routine servicing.
- Safety Isolation & Testing Points: Blind flanges enable pressure testing and line isolation without system modification—helpful in industrial parks and utility facilities.
Why Flange Quality and Specifications Matter
Choosing the wrong flange can cause leaks, corrosion, pressure failure, or costly downtime. When specifying flanges, consider:
Material Grade
- Carbon steel: economical, needs corrosion protection
- Stainless/alloy steel: ideal for harsh or high-moisture environments
Pressure Class
Flanges range from 150 lb to 2500 lb ratings. Match the rating to system pressure and operating temperature.
Face Style
- Raised-Face (RF): most common
- Ring-Type Joint (RTJ) or Flat-Face (FF): used for specialty or high-seal applications
Gasket Compatibility & Bolt Torque
Correct gasket material and bolt torque are critical for performance and longevity.
DS Pipe & Steel Supply offers fully rated flanges and matching gaskets to ensure your piping meets local codes, safety standards, and performance requirements.
