Custom Components for High-Purity Pipeline Systems
Custom components for high-purity pipeline systems are made of 316L VAR stainless steel (impurities ≤0.03%) or PVDF, including elbows, tees, reducers, etc., electropolished (Ra≤0.2μm) and auto-orbit welded (CSE standard). Featuring zero surface adsorption, particle shedding ≤0.1μm, and strong corrosion resistance (to electronic-grade acids/alkalis), they pass helium mass spectrometry leak detection (rate ≤1×10⁻⁹Pa·m³/s). The mirror-finish inner wall and dead-angle-free welding prevent media contamination, with passivation maintaining high-purity environments. Applied in semiconductor wafer cleaning lines, pharmaceutical aseptic liquid systems, PV silicon etching, and electronic special gas transmission, complying with SEMI F20 and ISO 14644-1 Class 5 cleanliness standards.
