Bend 90° PVDF

  Datasheet (PDF)

Manufactured by Georg Fischer and supplied across Europe through BigWeld, an authorised Georg Fischer distributor, the SYGEF Standard bend 90 degrees in PVDF is an engineered pipe fitting designed for directional flow changes in high-purity and aggressive chemical process pipelines. Produced from high-grade polyvinylidene fluoride to SDR21 wall ratio standards, this component delivers a continuous nominal pressure rating of PN16 across outer diameters ranging from d20 mm to d225 mm (DN15 to DN200) in strict dimensional conformance with ISO 10931. Precision injection moulding provides superior geometrical accuracy, stress-free wall distribution, and consistent material density, reliably accommodating a working temperature spectrum from -20 degrees C to +140 degrees C. Formulated for high-integrity industrial conveyance, the internal bore achieves an ultra-smooth finish with a surface roughness of Ra maximum 0.5 micrometres (20 microinches), preventing media contamination, reducing friction losses, and suppressing particle entrapment. For jointing, the extended spigot ends provide universal compatibility with butt fusion welding in accordance with DVS 2207-15, non-contact infrared fusion (IR Plus per DVS 2207-6), and bead and crevice free (BCF Plus) joining across dimensions up to d110 mm. This fabrication adaptability guarantees high weld seam repeatability across cleanroom and processing environments handling deionised water (DI), pharmaceutical-grade purified water (PW), and aggressive chemical circuits. The fluoropolymer construction withstands demanding sanitisation cycles involving live steam, hot water, ozone, or chemical agents. Fully compliant with FDA CFR 21 177.2510, USP 25 Class VI physiological non-toxicity standards, ASME BPE guidelines, DIBt criteria, and FM-4910 cleanroom listings, each bend features permanent embossed markings denoting brand, material, dimensional tolerances, pressure class, and batch lot numbers to ensure complete system traceability.
