Component Specifications

Definition
A flange or mounting ring is a mechanical component designed to create a stable, sealed connection point between the hopper funnel and adjacent equipment such as pipes, valves, or processing machinery. It typically features bolt holes for secure fastening and may include gasket surfaces to prevent material leakage. In hopper applications, it ensures structural integrity during material flow while allowing for maintenance access.
Working Principle
The flange or mounting ring operates on the principle of mechanical fastening and compression sealing. When bolted between mating surfaces, it creates a rigid connection that distributes loads evenly while compressing a gasket to form a leak-proof seal. This prevents material escape and maintains system pressure integrity during hopper funnel operation.
Materials
Common materials include carbon steel (ASTM A36), stainless steel (304/316), aluminum alloys, or engineered plastics like polyethylene for corrosion resistance. Material selection depends on the processed substance, temperature, and environmental conditions.
Technical Parameters
  • Diameter 100-500 mm
  • Thickness 5-20 mm
  • Bolt Holes 4-12 holes
  • Pressure Rating Up to 150 PSI
  • Temperature Range -20°C to 200°C
  • Bolt Circle Diameter Varies by flange standard
Standards
ISO 7005, DIN 2501, ASME B16.5

Frequently Asked Questions

What is the difference between a flange and a mounting ring?

Flanges typically refer to standardized connecting components with bolt patterns, while mounting rings may be custom-designed for specific equipment. Both serve similar attachment purposes but may differ in standardization and application.

How do I select the right material for a hopper funnel flange?

Consider the material being processed (corrosive, abrasive, food-grade), temperature requirements, pressure conditions, and cleaning protocols. Stainless steel is common for food and chemical applications, while carbon steel suits general industrial use.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
