Component Specifications

Definition
A flange plate is a critical mechanical component designed to facilitate the connection of two sections of piping or equipment. It typically features a flat, circular shape with a central bore and a series of bolt holes arranged around its perimeter. The primary function is to create a strong, pressure-resistant, and leak-proof joint when bolted to a mating flange, often with a gasket inserted between them. It is integral to flange assemblies in various industrial systems, enabling assembly, disassembly, and maintenance.
Working Principle
The flange plate works by providing a mating surface that, when aligned with another flange and compressed together with bolts, creates a sealed connection. The applied bolt torque generates clamping force, which compresses a gasket between the flanges to form a tight seal, preventing fluid or gas leakage while withstanding internal pressure and mechanical loads.
Materials
Common materials include carbon steel (e.g., ASTM A105), stainless steel (e.g., ASTM A182 F304/F316), alloy steel, and sometimes ductile iron or aluminum, selected based on pressure, temperature, corrosion resistance, and application requirements.
Technical Parameters
  • Diameter 50-600 mm
  • Face Type Raised face, flat face, ring-type joint
