Product Description
Sanitary - grade seamless pipes
Item | Details |
Material | Mainly high - quality stainless steels such as 304 and 316L, which have excellent corrosion resistance and stability |
Specification | The outer diameter usually ranges from 6 to 219 mm, and the wall thickness is 0.5 - 10 mm. Special specifications can be customized according to requirements |
Surface Treatment | The inner and outer surface roughness can reach Ra0.2 - 0.4μm, achieving a mirror - like effect |
Hygienic Standards | Strictly comply with international authoritative hygienic standards such as GMP, FDA, and 3A |



The product has outstanding advantages: Firstly, the extremely high surface finish and seamless design greatly reduce the possibility of bacteria and dirt adhesion, facilitating cleaning and disinfection. Secondly, the selected high - quality stainless - steel material not only has excellent corrosion resistance and can adapt to various acidic and alkaline environments but also has good high - temperature resistance and can be stably used in processes such as high - temperature sterilization. Furthermore, its precise dimensional control and excellent mechanical properties ensure reliability and durability during installation and use.
