Ultimate Corrosion-Resistant Piping for Harsh Industrial Applications
PTFE lined carbon steel pipes combine the structural strength of carbon steel with the unmatched chemical resistance of PTFE (Teflon), making them ideal for industries requiring durable, leak-proof, and corrosion-resistant fluid transfer systems.
Top 5 Industrial Applications
1. Chemical Processing Plants
✔ Acid & Alkali Transfer – Resists sulfuric, hydrochloric, nitric, and hydrofluoric acids
✔ Solvent Handling – Compatible with acetone, toluene, and chlorinated solvents
✔ High-Purity Lines – Prevents contamination in pharmaceutical intermediates
2. Oil & Gas (Sour Service)
✔ H₂S & CO₂ Resistance – Ideal for sour gas and corrosive crude oil
✔ Refinery Piping – Handles aggressive hydrocarbons and amine solutions
✔ Offshore Rig Applications – Withstands saltwater exposure
3. Pharmaceutical & Food Industries
✔ FDA-Compliant Lining – Safe for ultra-pure water and sterile fluids
✔ CIP/SIP Systems – Non-stick surface prevents bacterial buildup
✔ Biopharma Processing – Used in reactors and chromatography systems
4. Semiconductor Manufacturing
✔ Ultra-Clean Gas Delivery – Prevents particle contamination in wafer fabs
✔ Plasma Etching Gas Lines – Resists fluorine-based etchants (NF₃, SF₆)
✔ High-Purity Chemical Distribution – For photoresist and solvent systems
5. Power & Wastewater Treatment
✔ Flue Gas Desulfurization (FGD) – Resists sulfuric acid mist
✔ Bleach & Chlorine Lines – For water disinfection systems
✔ Scrubber & Effluent Piping – Handles abrasive slurries
