What is the difference between industrial stainless steel pipes and sanitary stainless steel pipes？

Industrial stainless steel pipes and sanitary stainless steel pipes are two different types of pipes. Their differences are mainly reflected in the material, production process, and internal and external surface finish.

In terms of material, industrial stainless steel pipes have ordinary requirements for stainless steel precision and mostly use ordinary 304 materials, while sanitary stainless steel pipes mostly use food-grade 316L materials, which are more corrosion-resistant than ordinary 304.

From the production process point of view, the production process of industrial stainless steel pipes is relatively simple, and only simple degreasing, passivation and other process treatments are required.

Sanitary stainless steel pipes require strict degreasing, degreasing, chemical brightening, electrolytic polishing and other process treatments to ensure that the inner wall of the pipeline is smooth and has no dead corners to prevent bacterial growth.

From the perspective of internal and external surface finish, the surface finish of industrial stainless steel pipes is low, generally only 2B board effect.

The surface finish of sanitary stainless steel pipes is high, and generally can achieve BA board effect.
This is because sanitary stainless steel pipes need to ensure the purity of the medium in the pipeline to prevent secondary pollution.

From the application field, industrial stainless steel pipes are mainly used in industrial fields such as chemical industry, petroleum, shipbuilding, etc.

Sanitary stainless steel pipes are mainly used in food, medicine, beverage and other industries. These industries have extremely high requirements for the purity of the medium in the pipeline and cannot have secondary pollution.

How should we choose the right stainless steel pipe?

First of all, we need to clarify the use environment and medium.
If it is used in industrial fields such as chemical industry and petroleum, industrial stainless steel pipes can be selected; if it is used in sanitary fields such as food and medicine, sanitary stainless steel pipes should be selected.

Secondly, we need to consider the price factor.
Generally speaking, the price of sanitary stainless steel pipes will be higher than that of industrial stainless steel pipes.
However, considering its excellent corrosion resistance and anti-pollution ability, this price difference is completely worth it.

Finally, we also need to consider the after-sales service of the supplier.
Choosing a supplier with good after-sales service can get timely solutions when there is a problem with the pipe.
