Component Specifications

Definition
A vertical pipe component in upper distributor/collector machines that serves as the primary conduit for fluid flow between different levels of the system. It typically connects the main distribution header to various branch lines or collection points, ensuring controlled directional flow with minimal pressure drop.
Working Principle
Utilizes gravitational and pressure differentials to facilitate vertical fluid movement. The pipe's internal geometry and diameter are designed to maintain laminar or controlled turbulent flow, preventing cavitation and ensuring consistent distribution/collection across connected subsystems.
Materials
Stainless steel (AISI 304/316), carbon steel (ASTM A106 Grade B), or corrosion-resistant alloys (Hastelloy, Inconel) depending on fluid properties. Wall thickness: 3-10mm based on pressure rating.
Technical Parameters
  • Diameter 50-300mm
  • Surface Finish Ra ≤ 3.2μm
  • Connection Type Flanged/Welded
  • Pressure Rating 10-100 bar
  • Temperature Range -20°C to 200°C
Standards
ISO 1127, DIN 2448, ASME B36.10M
