These MS PFA LINED Tee also has a high-robustness characteristic, as they have a composition of Cr has a significant impact and improves the strength to some extent. SS 316 PTFE Pipe Fittings provide a plethora of Chromium making it one of the most dependable options. SS 316 PFA LINED Pipe is currently used more in chemical industries. It has a low-maintenance design and tough construction. PTFE/FEP/PFA Lined Pipes are manufactured as per customer requirements and in strictly according to national and international quality specification.
We Galaxy Thermoplast Pvt. Ltd see to it that pipes are been inspected before they are delivered to our valuable clients, we follow destructive and non-destructive testing on these Pipes which are, PMI Intergranular Corrosion test , IGA, Roughness of surface measure, Radiation inspection, Fatigue test, Tension test, Flaring resistance, Chemical composition analysis. Mild Steel PTFE LINED Pipe is wrapped in required packaging material to avoid errors and destructions while delivery.

PTFE lined pipes carry highly corrosive chemicals concentrated acids, alkalis, solvents, and oxidising agents where unlined carbon or stainless steel would corrode within weeks. Chemical plants, pharmaceutical manufacturing, agrochemical processing, and semiconductor fabrication all specify them for fluid handling lines that cannot tolerate metal contamination or corrosion-driven leaks.
PTFE lining handles continuous service up to 180°C and intermittent peaks to 200°C. Above 200°C, the PTFE begins to deform under pipe pressure, so high-temperature applications above this range require PFA-lined alternatives rated to 260°C.
PTFE handles the widest chemical range and highest pressures but cannot be melt-processed, requiring sintering. FEP offers near-identical chemical resistance and welds cleanly as a liner, rated to 150°C continuous. PFA combines PTFE-level chemical resistance with melt-processability and rates to 260°C the correct choice for high-temperature corrosive service.
Yes. PTFE resists virtually all industrial chemicals except molten alkali metals and fluorine gas at elevated temperatures. Hydrofluoric acid, sulfuric acid, hydrochloric acid, and chlorine all fall within its compatibility range at operating concentrations used in standard chemical process lines.
Yes. PTFE lined pipes export to Norway and across Scandinavia with full EN 10204 3.1 material documentation, dimensional certification, and hydraulic test reports as standard. Lead times for export orders run 4–6 weeks from order confirmation depending on pipe size and quantity.
