Overview
A PTFE-lined steel pipeline is a composite industrial conduit designed to combine the structural strength of carbon steel with the superior chemical inertness of polytetrafluoroethylene. Manufactured according to general standards for corrosion-resistant piping, it features a seamless steel outer shell reinforced by a bonded PTFE inner liner.
Application
- Chemical Processing: Transporting aggressive acids, alkalis, and solvents in reactors and storage systems.
- Petrochemical Industry: Handling high-purity fluids and corrosive by-products in refining units.
- Pharmaceuticals: Conveying sterile reagents where product contamination must be strictly avoided.
- Environmental Engineering: Managing wastewater streams containing heavy metals or toxic compounds.
Precautions
- Maintain operating temperatures within the specified range to prevent liner deformation or delamination.
- Conduct periodic visual inspections for external dents or internal wear signs during scheduled maintenance.
- Ensure proper grounding to avoid static discharge risks when handling flammable media.
- Replace liners immediately upon detecting any breach to prevent catastrophic pipe failure.
