As a leading manufacturer, Wuxi Yansheng Technology Co., Ltd. specializes in producing high-grade stainless steel tubing for critical sanitary applications. Our 304 & 316L Stainless Steel Sanitary Precision Seamless Tube with Ep/Ba Grade is engineered to meet the stringent demands of industries where hygiene, corrosion resistance, and product purity are paramount. Established in 2017 and operating from a modern facility, we combine advanced manufacturing technology with rigorous quality control to deliver tubing that ensures system integrity and operational safety.
This product represents our commitment to excellence, offering a seamless, precision-formed conduit with an electropolished and bright annealed finish. It is designed to prevent contamination, resist harsh cleaning agents, and maintain a smooth, cleanable surface over long service periods.
Core Product Features & Technical Specifications:
-
Material Superiority: Available in two premium stainless steel grades:
- AISI 304: Excellent general corrosion resistance, good formability, and widely used in various sanitary environments.
- AISI 316L: Enhanced corrosion resistance due to molybdenum content, ideal for more aggressive chemical or chloride-containing environments.
- Seamless Precision Manufacturing: Produced using advanced piercing and extrusion techniques to create a tube without a longitudinal weld seam. This eliminates potential weak points, contamination risks from weld material, and ensures uniform wall thickness and structural integrity.
-
Ep/Ba Surface Finish:
- Electropolishing (Ep): An electrochemical process that removes a microscopic layer of surface material, smoothing the surface, reducing surface area, and enhancing corrosion resistance. It creates a mirror-like, ultra-clean interior crucial for preventing bacterial adhesion and biofilm formation.
- Bright Annealing (Ba): Heat treatment performed in a controlled atmosphere (often inert gas) to relieve stresses from cold working while maintaining a bright, oxide-free surface. This preserves the material's mechanical properties and the polished finish without scale formation.
-
Hygienic & Sanitary Design: The combination of seamless construction and high-polish finish meets the requirements for cleanability and sterility in applications like:
- Food & Beverage processing and transfer lines.
- Pharmaceutical and biotech fluid systems.
- Cosmetics and personal care product manufacturing.
- Dairy and brewery equipment.
- High-purity water systems.
- Customizable Dimensions & Configurations: We can produce tubes to your specific dimensional requirements, including outer diameter, wall thickness, and length. Tubes can be supplied straight or bent to specified geometries.
Key Technical Parameters (Typical Range):
| Parameter | Description / Typical Range |
| Material Grades | AISI 304, AISI 316L |
| Standard Outer Diameter (OD) | Available from small diameters for instrumentation to larger process lines |
| Wall Thickness (WT) | Customizable to meet pressure rating and mechanical strength needs |
| Surface Roughness (Ra) - Interior | Very low, typically < 0.5 μm after electropolishing |
| Tolerance on Dimensions | Precision tolerances on OD and WT per customer specification |
| Primary Applications | Sanitary, Hygienic, High-Purity Fluid Transfer |
Advantages & Client Benefits:
- Enhanced System Hygiene: The seamless, polished surface minimizes areas where contaminants can lodge, supporting easier cleaning, sterilization (e.g., CIP/SIP), and compliance with sanitary standards.
- Long-Term Corrosion Resistance: The high-grade materials combined with the Ep/Ba finish provide durable protection against corrosive process fluids, cleaning chemicals, and environmental factors, reducing maintenance and replacement costs.
- Improved Flow Characteristics: A smooth interior surface reduces friction and turbulence, promoting efficient fluid flow and potentially reducing pumping energy requirements.
- Structural Reliability: The seamless manufacturing process ensures consistent material properties and strength throughout the tube length, offering reliable performance under pressure and thermal cycles.
- Supply Chain Confidence: With our manufacturing expertise, significant annual export volume (US$50-100 Million), and presence in major global markets, clients receive products backed by industrial scale and proven logistics via ports like Shanghai, Tianjin, and Qingdao.
Frequently Asked Questions (FAQ):
-
What does "Ep/Ba Grade" specifically mean for this tube?
"Ep" stands for Electropolished, a finish that smoothens and passivates the surface. "Ba" stands for Bright Annealed, a heat treatment that maintains brightness without oxidation. Together, they denote a tube with a superior, clean, corrosion-resistant surface suitable for sanitary use. -
When should I choose 316L over 304 for my sanitary application?
Consider 316L if your process involves chloride-containing fluids (like certain brines or sanitizers), more aggressive acids, or operates in coastal environments. 304 is a robust and economical choice for many general food, dairy, and beverage applications. -
Can this tube be bent or fabricated into specific shapes?
Yes. While we supply straight precision seamless tubes, they can be further bent or fabricated by qualified processors. The material's properties are maintained, and we can discuss your specific fabrication needs. -
What are the cleaning and sterilization recommendations for this tube?
The Ep/Ba surface is designed for compatibility with common cleaning-in-place (CIP) and sterilization-in-place (SIP) protocols using hot water, steam, and approved chemical cleaners. Its smooth surface enhances cleaning efficiency. -
How does the seamless construction benefit a sanitary system compared to welded tube?
A seamless tube has no longitudinal weld seam, which can be a potential site for crevice corrosion, contamination trapping, or uneven material properties. Seamless offers a more uniform, reliable, and cleanable flow path. -
What dimensional tolerances can you achieve?
We manufacture with precision controls. Tolerances on outer diameter, wall thickness, and straightness can be tailored to your project's requirements. Please provide your specifications for a detailed discussion. -
Do you provide certification or test reports for the material?
Material certification confirming grade composition (e.g., 304 or 316L) can be provided. Other specific test reports (e.g., surface roughness, pressure testing) are available upon request. -
What is your typical production lead time and shipping capability?
Lead time depends on order quantity and specifications. With our established manufacturing base and access to major Chinese ports, we can efficiently arrange shipment to global destinations across our main markets.
Backed by a comprehensive quality management system and certifications, Wuxi Yansheng Technology delivers tubing that meets professional standards. Our 1,000-3,000 square meter factory and team of 101-200 dedicated employees ensure consistent production capacity and attention to detail.
