With the increasingly wide application of PFA hoses in high-end fields such as semiconductors, new energy and pharmaceuticals, standardized selection and scientific use have become the key to ensuring the safe and stable operation of fluid conveying systems. Recently, Jiangsu RANA Fluorine Material Technology Co., Ltd., which has been deeply engaged in the fluorine material field for 32 years, combined its own technical accumulation and a large number of practical application cases, released an authoritative guide for PFA hose selection and use, providing professional and comprehensive technical references for industry users.
In terms of selection matching, the guide clearly puts forward the principle of precise adaptation: for small and medium flow scenarios below DN40, specifications from DN10 to DN32 are preferred; specifications above DN50 are suitable for large flow conveying scenarios of more than 10 cubic meters per hour. Users can reasonably select products of corresponding specifications and reinforced structures according to actual flow, pressure, medium characteristics and temperature conditions. For DN100 large-diameter hoses, it is recommended to choose specifications with a wall thickness of 1.5~3mm or structures with fiber/steel wire reinforced layers to ensure structural stability under high-pressure working conditions.
In terms of installation precautions, the guide emphasizes three core points: first, the bending radius is recommended to be no less than 8 times the pipe diameter, avoid sharp tools scratching the pipe wall, and prevent hose damage caused by local stress concentration; second, for large-diameter hoses above DN80, it is recommended to support pipeline brackets to avoid deformation caused by long-term sagging, which affects the service life; third, strictly follow the joint assembly specifications during installation to ensure reliable connection and sealing and eliminate leakage risks.
In terms of service life cycle, the guide provides clear references combined with different usage scenarios: under static use in high-purity working conditions, the service life of PFA hoses can reach more than 10 years; for scenarios with frequent bending and movement, it is recommended to replace them every 3 to 5 years, regularly carry out inspections of hose appearance, sealing performance and cleanliness, and timely investigate potential safety hazards.
Industry technical experts said that the PFA hose selection and use guide released by Jiangsu RANA this time is based on the enterprise's 32 years of R&D and manufacturing experience in fluorine material products, which is professional, practical and authoritative. It will effectively help industry users standardize selection and scientifically use PFA hoses, reduce application risks, improve the operation stability and safety of fluid conveying systems, and promote the standardized and normalized development of the industry.
