一,The essential difference in material between food grade silicone tubing and stainless steel rigid tubing
Food-grade silicone tubes are mostly made of high-purity silicone rubber. They are usually made using platinum vulcanization or peroxide vulcanization processes. These tubes meet worldwide food safety standards like FDA, LFGB, USP Class VI, RoHS, REACH, and more. The best thing about this kind of silicone tube is that it doesn't smell or hurt you, is highly chemically stable, has good stiffness and flexibility, and works well across a wide temperature range.
Metals are used to make stainless steel pipes. 304 stainless steel and 316L stainless steel are the most popular types used in the food industry. Because it has more molybdenum, 316L is better at resisting corrosion, which is why it is used more in the pharmaceutical and high-purity businesses. The best things about stainless steel pipes are that they are strong, stiff, resistant to high pressure and impact, and have a stable structure that can be used for long-term fixing
二,Based on cleanliness and safety, can I trust food-grade silicone tubing?
Safety and cleanliness are always the most important things in the food and drug industries. In this way, food-grade silicone tubing is just as good as stainless steel when it comes to compliance.High-quality food-grade silicone tubing doesn't give off any harmful chemicals or smells, and it doesn't change the taste, makeup, or safety of the medium it's carrying. On the other hand, silicone has a very smooth surface that makes it hard for germs to grow. It's also not too hard to clean.
When it comes to temperature resistance, food grade silicone tubes can usually last a long time in temperatures between -40 °C and 180 °C. They can also last a short time at temperatures as high as 200 °C, which is enough for the processes of pasteurization, steam disinfection, and hot water cleaning
三, From the point of view of how well it works mechanically and how it's built, why can't it be totally replaced
To begin, there is a big difference in the voltage resistance. Food grade silicone hoses are flexible hoses, and they can generally handle pressures of 0.2 MPa to 1.0 MPa. Even silicone tubes that are thick or made of fibers are not able to stand up to high pressures for long periods of time. Most stainless steel hard pipes can withstand pressures of more than 5 MPa to 20 MPa. This makes them almost unusable in systems that use high-pressure pumps, make fizzy drinks, or ferment food.
The next issue is the safety of the structure. Because silicone tube is flexible, it can bend, stretch, and change shape. It can't hold the system up, though. To add to that, the stainless steel pipes are part of the structure of the equipment. They can be attached to brackets, hold weight, and even help design the general equipment's mechanical strength.
There is also a gap in the working life. Under normal working conditions, stainless steel hard pipes can last up to 10 or even 20 years. On the other hand, food grade silicone hoses are pretty much disposable, and their service life is only 6 to 2 years, depending on temperature, pressure
四, When can food-grade silicone tubing be used instead of hard stainless steel tubing
there's the internal link system of small appliances like coffee makers, water dispensers, and filling machine pipes. This kind of equipment needs a lot of bending and flexible connections because it takes up a lot of room and has a complicated structure. When it comes to flexibility, silicone tube is much better than stainless steel.
There are then trial production lines and temporary conveying systems, which are used for short-term projects and things like making samples, checking samples, and making samples. Installing stainless steel pipes takes time and money. Silicone pipes, on the other hand, can be put in and used right away. This makes them perfect for quick deployment.
The third type is systems that need to be taken apart and cleaned often, like filling equipment, CIP cleaning systems, and testing devices. Silicone tubing is easy to take apart and put back together again, which cuts down on maintenance time and work costs by a large amount.
五, Can food-grade silicone tubing be used instead of hard stainless steel tubing
It is possible to come to a very clear, professional, and appropriate decision for SEO summary by looking at a number of factors, including material properties, hygiene and safety, mechanical performance, engineering structure, and cost.Food grade silicone tubing can't fully replace stainless steel rigid tubing at the engineering structural level, but it can be a great partial replacement in situations with low pressure, flexibility, frequent disassembly, and high cleanliness. In some fields, it's even better than stainless steel.
