DN300 Flange Type NBR Single Sphere Flexible Expansion Connection Rubber Compensator Joint

A Single Sphere Rubber Expansion Joint (also known as a rubber compensator, flexible rubber joint, or rubber bellows) is a highly flexible piping component designed to absorb movement, reduce vibration, and compensate for misalignment in pipelines while maintaining a leak-proof seal.

Key Features
  • Nominal Diameter (DN): 300 mm
  • Structure Type: Single Sphere Rubber Expansion Joint
  • Flange Type: Carbon steel or galvanized steel, drilled to ANSI, DIN, JIS or custom standards
  • Rubber Material: NBR (Nitrile Butadiene Rubber) - Excellent oil resistance
  • Reinforcement: Multi-layer nylon cord and steel wire for pressure resistance
  • Design Pressure: Usually PN10 / PN16 / PN25 (confirm as per project)
  • Movement Capability: Axial compression/extension, lateral offset, angular deflection
  • Temperature Range: -10°C to +80°C (depending on fluid compatibility)

Construction Details

The single sphere rubber expansion joint consists of:

  • Rubber Body (Elastomer): Typically made of NBR (Nitrile Rubber), EPDM, Neoprene, or FKM (Viton) depending on the application.
  • Reinforcement Layers: Embedded fabric or steel wire to enhance pressure resistance.
  • Flanges or Pipe Ends: Available in flanged (ANSI, DIN, JIS, etc.) or threaded/sleeve-type connections.
  • Single Arch (Sphere) Design: Provides flexibility for axial, lateral, and angular movement.

Key Functions
✔
Vibration & Noise Damping: Reduces stress from pumps, compressors, and machinery.
✔
Shock Absorption: Protects pipelines from water hammer and pressure surges.
✔
Misalignment Compensation: Allows slight pipe deviations without rigid connections.
✔
Thermal Expansion Compensation: Accommodates temperature-induced pipe expansion/contraction.
✔
Chemical & Corrosion Resistance: Depending on rubber material (e.g., EPDM for acid, NBR for oils).
