Baffle Types

  • Single Segmental Baffle
    Most commonly used configuration for directing shell-side flow across the tube bundle.
  • Double Segmental Baffle
    Used where lower pressure drop and alternative flow distribution are required.
  • Disc & Donut Baffle
    Alternating disc and donut arrangement directs shell-side flow through the tube bundle.
  • Orifice Baffle
    Designed with controlled openings to regulate shell-side flow and pressure drop.
  • Support Baffle
    Provides tube-bundle support and helps reduce tube vibration.

Design Features

  • Accurate tube-hole positioning
  • Controlled baffle cut
  • Proper tube clearance
  • Smooth machined edges
  • Tube-support and anti-vibration design
  • Custom baffle spacing
  • Rod and spacer-hole machining
  • Suitable for horizontal and vertical exchangers
