Core Tube Component – Machinery and Equipment Manufacturing

Component Specifications

Definition

The core tube is the central cylindrical component within a filter cartridge that provides structural support to the filtration media (such as pleated paper, mesh, or synthetic fibers). It maintains the media's shape and spacing during operation, prevents collapse under pressure differentials, and serves as the central channel for filtered fluid collection and discharge. Core tubes feature precise perforation patterns to optimize flow distribution while retaining media particles.

Working Principle

Acts as a rigid backbone for the filtration media, allowing fluid to pass through the media into the central channel while supporting the media against pressure forces. The perforated design creates uniform flow paths and prevents media deformation.

Materials

Typically made from polypropylene (PP), stainless steel (304/316), galvanized steel, or aluminum. Material selection depends on chemical compatibility, temperature range, and pressure requirements.
