Products Description
This series of food-grade metal hoses are integrally welded and formed from virgin food-grade 316L stainless steel. The inner wall is precisely mirror-polished with no micropores, no dead corners and no material adhesion, fundamentally avoiding medium residue and bacterial reproduction. The outer high-density stainless steel braided layer provides wear resistance, tensile resistance and explosion-proof protection, balancing structural strength and flexible performance. With no adhesive layer or harmful additives, the hose supports long-term scouring of high-temperature steam, hot water and clean fluids, as well as repeated CIP online cleaning and SIP high-temperature sterilization, perfectly adapting to high-frequency disinfection clean production scenarios. Featuring excellent flexibility, it allows multi-angle free bending without dead folding, effectively compensating for equipment operation vibration, pipeline thermal expansion and contraction displacement, and installation misalignment. Equipped with hygienic quick-clamp, thread and flange joints, it enables tool-free quick assembly without sanitary dead corners. With excellent temperature resistance, chemical corrosion resistance and pressure resistance, it maintains stable sanitary performance for long-term continuous operation without rusting or debris falling off, ensuring pure and sterile conveying media.
Product Advantages
Food-grade sanitary safety with zero residue and sterility Manufactured with 316L food-grade stainless steel and compliant with FDA food contact standards, the mirror-polished inner wall avoids medium adhesion and bacterial growth during the transportation of dairy products, juice, wine, liquid medicine and other clean media. No heavy metal or harmful substances precipitate, completely preventing secondary medium pollution and meeting high-standard clean production requirements.
Repeated high-temperature sterilization with stable heat resistance Superior to ordinary plastic food hoses, it withstands long-term high-temperature steam and boiling water scouring, supporting repeated 135℃ high-temperature sterilization and online cleaning. It will not soften, age or deform under high temperature, maintaining stable performance during alternating cold and hot conditions to adapt to high-frequency sterilization production in food and pharmaceutical industries.
Flexible explosion-proof and pressure-resistant with high working stability The corrugated body combined with multi-layer stainless steel braided structure delivers strong pressure resistance, tensile resistance and explosion-proof performance, eliminating hidden dangers of hose bulging, bursting and leakage caused by dynamic pressure fluctuation. With excellent bending flexibility, it can be flexibly arranged in narrow spaces without collapse or blockage after bending, adapting to dynamic equipment displacement and fine pipeline adjustment.
Corrosion and aging resistance for extended service life The 316L stainless steel substrate resists acids, alkalis, moisture and cleaning agent corrosion, tolerating long-term scouring of fruit acid, wine solvents and disinfectant without rusting, oxidation or chipping. With greatly improved aging and fatigue resistance compared with ordinary food hoses, it supports long-term continuous operation and reduces consumable replacement costs effectively.
Sanitary quick-install design for convenient maintenance Equipped with standard food-grade sterile quick-install joints for tight docking without sanitary dead corners. Tool-free assembly and disassembly facilitates rapid cleaning and maintenance. The dead-corner-free structure adapts to automatic CIP cleaning systems, lowering manual cleaning costs and improving production line cleanliness and efficiency.

Product Q&A
Q: What is the difference between food grade metal hoses and ordinary metal hoses?
A: Ordinary metal hoses have rough inner walls that are prone to residue and impurity precipitation, only suitable for ordinary industrial fluids. Food grade metal hoses adopt 304/316L high-purity sanitary materials with mirror-polished dead-corner-free inner walls, featuring non-toxicity, pollution resistance and easy sterilization. Compliant with food and pharmaceutical safety standards, they are specially used for high-end clean and aseptic transmission scenarios contacting food and medicinal liquid with zero medium pollution risk.
Q: Can the food grade metal hoses withstand high-temperature disinfection and online cleaning?
A: Yes. With a wide temperature resistance range, the hose withstands high-temperature steam sterilization, hot water disinfection and CIP online circulating cleaning. It maintains stable performance without deformation, aging or harmful precipitation during long-term high-temperature operation, with no material residue after cleaning, fully meeting the high-frequency disinfection production needs of food and pharmaceutical industries.
Q: Is it suitable for alcohol, dairy and medicinal liquid transmission?
A: Yes, it is fully applicable. The 316L food-grade material resists corrosion from alcohol, weak acid, weak alkali and grease, with stable chemical properties and no reaction with transmission media. It will not change the taste, purity and efficacy of materials, serving as a special pipeline for brewing, dairy processing and pharmaceutical production lines.
