PVDF Pipe

  Datasheet (PDF)

Georg Fischer SYGEF Standard SDR33 PN10 pipes are engineered from high-grade polyvinylidene fluoride (PVDF) to deliver exceptional reliability and high purity performance in demanding industrial chemical distribution and purified water networks. Designed for metric dimensional outside diameters ranging from d90 mm up to d315 mm with a standard pipe length of 5 meters, these extruded pipes feature a pressure rating of PN10 at 20 degrees Celsius with a broad operational temperature range from -20 degrees Celsius to 140 degrees Celsius. The manufacturing process incorporates controlled thermal annealing to ensure low internal stress, maintaining dimensional stability and optimal roundness throughout system integration. Offering superior chemical resistance against aggressive acids, non-oxidizing media, organic compounds, and aliphatic hydrocarbons, the pipes maintain outstanding mechanical integrity up to their melting point above 175 degrees Celsius. The smooth extruded inner surface achieves a roughness profile of Ra ≤ 0.5 µm, minimizing biofilm formation, particulate traps, and flow resistance, which makes them ideal for pharmaceutical purified water (PW), deionized (DI) water loops, and continuous sanitization protocols using hot water, steam, chemicals, or ozone. For contamination-free jointing, the piping seamlessly integrates with Georg Fischer IR Plus infrared welding in accordance with DVS 2207-6, bead and crevice-free (BCF Plus) fusion for smaller diameters up to d110 mm, and conventional butt fusion jointing per DVS 2207-15. Each pipe length is supplied with protective end caps to preserve cleanliness during transport and handling, complies with FDA 21 CFR 177.2510, USP 25 Class VI physiological non-toxicity, and ASME BPE criteria, and carries permanent embossed production markings ensuring comprehensive lot traceability from raw polymer to the jobsite.
