Overview
Anhui Xinfulong offers high-performance fluoropolymer sheet linings engineered to protect chemical process equipment from corrosion while maintaining the highest levels of purity-. Our sheet lining solutions are fabricated from premium virgin fluoropolymer materials including PTFE, PFA, and modified PTFE, providing exceptional chemical resistance, thermal stability, and non-stick properties for the most demanding applications in the semiconductor, wet chemical, new energy, pharmaceutical, and fine chemical industries.
What Is Sheet Lining?
Sheet lining is a fluororesin lining process in which sheets made of PTFE, PFA, or other fluoropolymers are applied to the interior surfaces of metal equipment such as tanks, reactors, columns, and piping systems. This method allows for thicker linings compared to many other fluororesin lining techniques, resulting in superior corrosion resistance and extended service life. The linings are fabricated using specialized fusion welding and forming technology, with sheets available in thicknesses ranging from 1.5mm to 4.7mm (60 mil to 180 mil).
Material Options
Key Features & Benefits
-
Exceptional Corrosion Resistance — Fluoropolymer sheet linings provide broad-spectrum chemical resistance, far exceeding the corrosion protection of other plastic, glass, and high-nickel alloy materials-. They are chemically inert and resistant to virtually all chemicals except molten alkali metals, fluorine, and certain complex halogenated compounds at elevated temperatures-.
-
High Purity & Non-Contamination — Sheet linings preserve the purity of processing streams, making them ideal for semiconductor and pharmaceutical applications where contamination control is critical-. Our linings are fabricated with strict quality control to minimize metal ions, particles, and impurities.
-
Thermal Stability — Fluoropolymer sheet linings maintain their integrity across a wide temperature range, with PTFE and PFA materials capable of withstanding temperatures up to 260°C while maintaining chemical inertness.
-
Non-Stick Surface — The smooth, non-stick surface finish provides excellent release properties, reduces product buildup, and simplifies cleaning and maintenance.
-
Custom-Engineered Solutions — Linings are custom-fabricated to fit a wide variety of metal and fiberglass structures, including columns, heat exchanger shells, pressure vessels, high-purity day tanks, storage tanks, vessel covers, filters, scrubbers, processing chambers, and more.
