Component Specifications

Definition
A corrosion liner or cladding is a specialized protective layer bonded or applied to the interior surface of pressure vessel shells to isolate the base metal from corrosive process fluids, chemicals, or environments. This component functions as a barrier against chemical attack, erosion-corrosion, and stress corrosion cracking, maintaining structural integrity while preventing contamination of stored or processed materials. It is engineered to withstand specific temperature, pressure, and chemical exposure conditions typical in industrial applications.
Working Principle
The corrosion liner/cladding operates on the principle of sacrificial or barrier protection. It creates a continuous, impermeable layer between the corrosive medium and the vessel's structural material (typically carbon or low-alloy steel). By selecting materials with superior corrosion resistance (e.g., stainless steels, nickel alloys, polymers, or ceramics), it prevents direct contact and electrochemical reactions that would degrade the base metal. The liner may be mechanically bonded, welded, or chemically adhered to ensure no gaps or disbonding under operational stresses.
Materials
Common materials include austenitic stainless steels (304L, 316L), duplex stainless steels (2205), nickel alloys (Inconel 625, Hastelloy C-276), titanium alloys, glass-reinforced epoxy (GRE), polypropylene (PP), fluoropolymers (PTFE, PVDF), and ceramic coatings. Selection depends on chemical compatibility, temperature range (-50°C to 400°C typical), pressure, and mechanical properties.

Engineering Analysis

Risks & Mitigation
  • Liner disbonding due to thermal cycling
  • Crack propagation from mechanical stress
  • Chemical permeation leading to base metal corrosion
  • Improper installation causing leaks
FMEA Triads
Trigger: Thermal expansion mismatch between liner and base metal
Failure: Cracking or disbonding of liner
Mitigation: Use materials with compatible thermal coefficients; design expansion joints; control heating/cooling rates

Frequently Asked Questions

What is the difference between a liner and cladding?

A liner is typically a separate sheet or layer mechanically attached or loosely fitted, while cladding is metallurgically bonded (e.g., weld overlay, explosion bonding) to the base material, offering better thermal and mechanical integration.

How often should corrosion liners be inspected?

Inspect during regular pressure vessel shutdowns, typically every 12-24 months, using non-destructive testing (NDT) like ultrasonic testing (UT) or visual inspection for cracks, disbonding, or thinning.

Can a damaged corrosion liner be repaired?

Yes, localized repairs are possible via welding, patching, or reapplication of coating, but must comply with original design standards and be tested for integrity post-repair.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
