Top 10 things to consider when buying seamless stainless steel sanitary pipes

What is a sanitary seamless stainless steel pipe?

Sanitary seamless stainless steel pipes are mainly used in the production of food and other edible items. Simply put, they are a kind of steel pipe material used in the production of food. This kind of sanitary stainless steel pipe is mainly used in the production equipment or production lines of some food, and can also be used in beverages, alcoholic beverages, and bioengineering. Its safety standards for dry edible items are very strict.

Advantages of sanitary stainless steel pipes:

1. Compared with ordinary stainless steel seamless pipes, the main difference is that the inner surface is polished, which will reduce resistance and increase fluidity when conveying fluids, so that the stainless steel in the fluid is not mixed with the pipe wall debris peeled off by the impact of the fluid, and the inner wall of the steel pipe is not easy to scale, ensuring hygiene and safety performance.

2. Compared with plastic pipes, the characteristics are: first, the hardness and bearing pressure of stainless steel pipes are much greater than those of plastic pipes, which increases safety, makes the pipe body less likely to burst, and reduces safety accidents and liquid leakage losses; second, sanitary stainless steel pipes do not contain metal precipitation that is harmful to the human body, while the polyethylene in plastic pipes is harmful to the human body; finally, the fluid resistance of sanitary stainless steel pipes is smaller than that of plastic pipes, and it is not easy to cause secondary pollution caused by pipe wall debris and scaling.

The top 10 concerns when purchasing seamless stainless steel sanitary pipes are as follows:

1. Material and certification
Seamless stainless steel sanitary pipes are pipes made of stainless steel as a material and made through a seamless tube production process. They are widely used in food, pharmaceutical, cosmetic and other sanitary applications. Seamless stainless steel pipes are used in different environments and use different materials. Choose the appropriate stainless steel material according to the specific usage scenario, such as 304 stainless steel, 316 stainless steel, 321 stainless steel, etc.

Customers are concerned about whether the purchased stainless steel seamless pipes meet the sanitary industry standards, such as whether they have passed international sanitary certifications, such as ISO certification, etc.

2. Surface treatment
Stainless steel pipes can be treated with different surface treatments, such as pickling, polishing, etc., and the appropriate surface treatment method should be selected according to needs. Surface quality is crucial for sanitary pipes. Customers are concerned about whether there is a smooth and defect-free surface to prevent microbial growth and product residues.

3. Corrosion resistance
Sanitary pipes are often used in environments involving food, beverages and pharmaceuticals, so corrosion resistance is information that customers are very concerned about. Seamless stainless steel sanitary pipes should be corrosion-resistant to ensure that the pipes will not be corroded during use.

4. Cleanability
Sanitary pipes need to maintain a high degree of cleanliness to meet hygiene standards. Customers care whether the pipes are easy to clean and do not leave any residue on the inner wall.

5 Size and Specifications
Customers need to choose the appropriate pipe size, including diameter and wall thickness, according to actual needs. This depends on factors such as the type of fluid or gas transported by the pipeline, flow rate, and working pressure to ensure a perfect match with their systems and equipment.

6. Pressure and temperature capabilities
Stainless steel sanitary pipes should have sufficient pressure and temperature resistance to ensure that no leakage or failure occurs under working conditions.

7. Weldability
Sanitary pipes may need to be welded, and customers are concerned about the weldability of stainless steel materials to ensure the stability and reliability of the welding process.

8. Safety certification
Customers are concerned about whether the pipeline meets international safety certification standards to ensure that it will not cause harm to the human body and the environment during use.

9. Cost and cost-effectiveness
Customers want to understand the cost and cost-effectiveness of stainless steel sanitary pipes to ensure the best economic benefits while meeting quality requirements.

10. Supply capacity and after-sales service
Customers are concerned about whether suppliers can supply seamless stainless steel sanitary pipes in a timely manner, and choose suppliers with reputation and good after-sales service to purchase stainless steel seamless pipes to ensure stable product quality and perfect after-sales service, such as technical support and after-sales maintenance.

The above are the top 10 information that customers are most concerned about when purchasing stainless steel sanitary pipes. Suppliers should provide clear and accurate product information and ensure that the products meet international standards and customer needs.
