Product Description

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.

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.
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 but also has good high-temperature resistance and can be stably used in processes such as high-temperature sterilization.

Frequently Asked Questions

What factors affect the price of stainless steel seamless pipes?

The price is influenced by material grade (e.g., 304 vs 316L), technical specifications, market supply and demand, and the cost of raw materials like nickel and chromium. Large-diameter and thick-walled pipes typically have higher production costs.

How do you ensure the quality of your pipes?

We conduct comprehensive quality checks including: Appearance Check (surface defects), Dimension Measurement, Nondestructive Testing (ultrasonic/eddy current flaw detection), Chemical Composition Analysis, and Mechanical Properties Testing.

Do you offer customized stainless steel products?

Yes, we provide customization services for seamless stainless steel tubes based on specific requirements, including various sizes, material grades, and specialized surface treatments.

Which international standards do your products comply with?

Our products comply with National Standards (GB), International Standards (ISO), and specific industry standards such as ASTM, AISI, and JIS.

What is the typical delivery timeframe?

Delivery time depends on order volume and specifications. Generally, orders are fulfilled within 2 to 4 weeks. Exact timelines are confirmed upon order placement.

What surface finishes can be achieved for sanitary pipes?

For sanitary applications, we can achieve inner and outer surface roughness of Ra0.2 - 0.4μm, providing a mirror-like finish that prevents microbial growth.
