In the food and beverage industry, the safety, hygiene, and durability of transportation pipes directly affect product quality and production efficiency. The 304/316L austenitic stainless steel pipes, with their excellent performance, have become the preferred choice in the industry.
The stainless steel pipes for beverage transportation mainly use 304/316L austenitic stainless steel. The material complies with GB/T 29038-2012, the standard for food-contact stainless steel products.
304 stainless steel has 18%-20% chromium and 8%-12% nickel. Its carbon content is ≤0.08%. This type resists corrosion from most acidic drinks.
316L stainless steel adds 2%-3% molybdenum and has a lower carbon content of ≤0.03%. It offers better protection against pitting and intergranular corrosion. This makes it ideal for transporting highly corrosive beverages like fruit juices and carbonated drinks.
Both materials strictly control the content of harmful elements such as lead and cadmium, and meet international food contact safety certifications, including FDA and LFGB, ensuring that no harmful substances are released during transportation.
The surface treatment adopts food-grade polishing technology. The roughness of the inner surface is Ra ≤ 0.8 μm, and for some high-end products, it can reach Ra ≤ 0.4 μm.
By combining mechanical and chemical polishing, impurities and burrs on the inside and outside of the pipe are removed, forming a smooth, dense surface layer. This not only prevents bacterial growth from residual beverages but also reduces fluid resistance.
The pipe openings are welded seamlessly, and the welds undergo flaw detection and polishing treatment. They form an integrated structure with the pipe body, without any joint dead corners, eliminating pollution risks. Some products can also undergo passivation treatment, as required, further enhancing surface corrosion resistance.
The 304/316L austenitic stainless steel pipes for beverage transport have stable chemical properties. They don’t react with drinks, so they keep the original flavor and nutritional value intact.
They meet the high-standard hygiene requirements for drinking water, fruit juices, dairy products, etc. They can withstand the erosion of acidic substances, sugar, etc. in beverages and are not prone to rust or aging. Their normal service life can reach 15-20 years, reducing replacement costs. The smooth inner surface reduces energy consumption during transportation, improves efficiency, and enables online CIP cleaning, reducing cleaning time and costs.
We can provide customized pipes in different diameters and wall thicknesses. They fit various joints and valves. These pipes are ideal for production line transport, tank area connections, and long-distance distribution. Plus, they allow for easy installation and maintenance.
The 304/316L austenitic stainless steel pipes are ideal for beverage transport. Their safe material and precise process ensure reliable performance. These pipes are essential for food and beverage companies. They help maintain product quality and boost production efficiency. This supports the industry’s goal of safe, efficient, and sustainable growth.
