Component Specifications

Definition
A connection flange is a precision-engineered mechanical component designed to create a secure, leak-proof joint between an outlet nozzle/port and a valve in industrial fluid handling systems. It features bolt holes, sealing surfaces, and standardized dimensions to ensure proper alignment, pressure containment, and easy maintenance access.
Working Principle
The flange creates a mechanical connection by clamping two mating surfaces together with bolts, compressing a gasket between them to form a pressure-tight seal. It transfers mechanical loads while allowing controlled fluid flow between the nozzle and valve.
Materials
Carbon steel (ASTM A105), stainless steel (AISI 304/316), alloy steel, or ductile iron with corrosion-resistant coatings where required.
Technical Parameters
  • Face Type Raised face (RF), flat face (FF), ring-type joint (RTJ)
  • Surface Finish 125-250 µin Ra for sealing surfaces
  • Pressure Rating 150-2500 PSI
  • Temperature Range -20°C to 400°C
  • Bolt Hole Quantity 4, 8, 12, or 16 holes
  • Bolt Circle Diameter Standardized per ASME B16.5
Standards
ASME B16.5, ISO 7005-1, DIN 2501, EN 1092-1

Engineering Analysis

Risks & Mitigation
  • Gasket failure leading to leaks
  • Bolt over-torquing causing flange warpage
  • Corrosion in aggressive environments
  • Improper alignment causing stress concentrations
FMEA Triads
Trigger: Incorrect bolt torque sequence
Failure: Uneven gasket compression and leakage
Mitigation: Use calibrated torque wrenches and follow cross-pattern tightening procedures
Trigger: Thermal cycling without expansion joints
Failure: Flange cracking due to thermal stress
Mitigation: Install expansion loops/bellows and use flexible gaskets

Frequently Asked Questions

What is the difference between raised face and flat face flanges?

Raised face flanges have a small raised section around the bore for gasket compression, while flat face flanges have full contact surfaces. RF is standard for higher pressure applications.

How do I select the correct flange material for corrosive fluids?

Select stainless steel (316 for chlorides) or apply protective coatings. Consider fluid chemistry, temperature, and pressure when specifying materials.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
