Overview
A PTFE-lined stainless steel pipeline is a composite industrial conduit designed for high-purity fluid transport. It features a corrosion-resistant fluoropolymer inner liner bonded within a structural carbon or stainless steel outer jacket, adhering to ASTM F1545 standards for chemical inertness and mechanical strength.
Application
- Petrochemical: Handling aggressive acids, solvents, and high-temperature hydrocarbons.
- Semiconductor: Ultra-high purity gas and chemical delivery systems.
- Pharmaceutical: Sterile process lines requiring non-contaminating surfaces.
- Environmental: Wastewater treatment and slurry transport in corrosive environments.
Precautions
- Temperature Limits: Avoid exceeding the PTFE continuous service rating of 260°C to prevent liner degradation.
- Bending Radius: Maintain minimum bending radii during installation to prevent liner wrinkling or delamination.
- Maintenance: Conduct periodic visual inspections for external dents and pressure testing every six months to ensure integrity.
