Component Specifications

Definition
The Inner Support Core is a precision-engineered cylindrical component within high-pressure oil filter cartridges, designed to provide structural reinforcement to filter media while maintaining optimal flow characteristics. It prevents media collapse, channeling, and deformation under operating pressures up to 1000 psi, ensuring consistent filtration performance throughout the service life.
Working Principle
Functions as a rigid backbone that distributes hydraulic pressure evenly across the filter media surface, preventing localized stress concentrations. The perforated design allows controlled fluid passage while supporting the pleated or wound filter material against compressive forces, maintaining uniform filtration pathways and preventing bypass.
Materials
Stainless steel 316L (ASTM A240) or carbon steel with epoxy coating; Alternative: Glass-filled polypropylene for corrosion-resistant applications; Material thickness: 0.8-1.2mm; Surface finish: Ra ≤ 1.6μm
Technical Parameters
  • Height Range 100-500mm
  • Burst Pressure ≥1500 psi
  • Diameter Range 50-200mm
  • Pressure Rating Up to 1000 psi (69 bar)
  • Collapse Pressure ≥1200 psi
  • Temperature Range -40°C to 150°C

Frequently Asked Questions

What happens if the inner support core fails?

Core failure leads to filter media collapse, causing reduced filtration efficiency, increased pressure drop, potential bypass of contaminants, and complete system failure in extreme cases.

Can inner support cores be reused?

Generally not recommended. Repeated pressure cycling causes material fatigue, and cleaning may not restore structural integrity. Always replace with filter cartridge changes.

How do I select the right support core material?

Consider operating fluid compatibility, pressure requirements, temperature range, and corrosion resistance. Stainless steel offers superior strength, while coated carbon steel provides cost-effective solutions for standard applications.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
