Industry News: Corrosion, leakage and contamination at equipment openings under highly corrosive working conditions have long restricted the safe operation of equipment in the chemical, semiconductor and new energy fields. With 32 years of accumulated fluorine material technology, Jiangsu RANA has developed a PFA single-flange nozzle, which addresses industry pain points with four hardcore performances: corrosion resistance, cleanliness, sealing reliability, and temperature stability, becoming the "safety heart" of medium and high-end anti-corrosion equipment.
In terms of corrosion resistance
Jiangsu RANA's PFA nozzle can withstand most highly corrosive media such as hydrofluoric acid, concentrated alkali, NMP, and electronic-grade hydrofluoric acid. Its corrosion rate is less than 0.01mm/year at 150℃, easily coping with extreme corrosive working conditions that metal materials such as stainless steel and Hastelloy cannot tolerate, fundamentally eliminating the risk of corrosion and perforation at equipment openings.
Cleanliness performance directly meets the core needs of semiconductors and biomedicine
Its semiconductor-grade product has a metal ion precipitation of <1ppb, TOC precipitation of <0.1μg/cm², and inner wall roughness Ra<0.2μm, with no risk of medium contamination. It perfectly matches the ultra-clean process requirements of wafer manufacturing and sterile drug production, supporting the stable mass production of 14nm and below advanced semiconductor processes.
Sealing reliability and temperature stability build a solid safety defense line
The flange face flatness tolerance of this nozzle is <0.05mm, free of defects such as sand holes and bubbles, with zero leakage under 1.5 times the rated pressure. Its long-term operating temperature ranges from -80℃ to +260℃, and it shows no cracking or deformation after 100 cycles of cold and hot shock between -40℃ and 180℃, adapting to extreme temperature working conditions such as high-temperature disinfection and cryogenic reaction.
Industry experts point out that most low-priced PFA nozzles on the current market use recycled materials or have process defects, which are prone to problems such as microcracks in the flange and uneven wall thickness, and may leak within 6 months under high temperature and high pressure. Jiangsu RANA insists on using high-purity virgin PFA resin, implements strict quality control throughout the entire process, and provides full traceability from raw materials to finished products, providing customers with long-term stable and reliable anti-corrosion sealing solutions.
