Component Specifications

Definition
An internal distributor is a precision-engineered component installed within vessels, shells, or tanks to ensure uniform distribution or collection of fluids (liquids, gases, or multiphase media) across the cross-sectional area. It prevents channeling, dead zones, and uneven flow patterns that compromise process efficiency, mixing quality, reaction kinetics, or separation performance in industrial equipment.
Working Principle
The internal distributor operates by directing incoming fluid through a network of channels, perforations, or nozzles arranged to cover the vessel's cross-section uniformly. It utilizes pressure drop, flow resistance balancing, and geometric design to achieve equal flow distribution. In collection mode, it gathers fluid from multiple points to maintain consistent withdrawal rates.
Materials
Stainless steel (AISI 304/316/L), carbon steel (ASTM A516), duplex steels, nickel alloys (Inconel, Hastelloy), titanium, PTFE-lined steel, or fiber-reinforced polymers, selected based on corrosion resistance, temperature, pressure, and fluid compatibility.
Technical Parameters
  • Flow Capacity 10-5000 m³/h
  • Connection Type Flanged, welded, or threaded
  • Pressure Rating Up to 100 bar
  • Design Standards ASME BPVC, PED 2014/68/EU
  • Temperature Range -50°C to 400°C
  • Distribution Uniformity >95%
Standards
ISO 9001, ASME B31.3, DIN 28000

Frequently Asked Questions

What is the primary function of an internal distributor in a vessel?

To ensure uniform fluid distribution across the vessel's cross-section, preventing flow maldistribution that can reduce process efficiency, cause hotspots, or degrade product quality in mixing, reaction, or separation processes.

How do you select materials for an internal distributor?

Material selection depends on fluid corrosivity, temperature, pressure, and cleanliness requirements. Common choices include stainless steel for general use, nickel alloys for high corrosion resistance, and polymers for chemical compatibility.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
