Product Description

Product Description

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

  Sanitary - grade seamless pipes are specifically designed and produced to meet stringent hygienic standards. They play an indispensable role in industries with extremely high requirements for sanitary conditions, such as the food, pharmaceutical, and cosmetics industries. These pipes are made from high - quality stainless - steel billets, processed through advanced cold - drawing or cold - rolling techniques, and combined with precise polishing treatments. This ensures that the inner and outer walls of the pipes are as smooth as mirrors, free from any welds, sand holes, or impurities, effectively preventing the growth of microorganisms and material residues, and safeguarding the purity of products.
  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.
