Product Description
Stainless Steel Market Ltd has a large inventory of high-quality stainless steel seamless tube to meet the harshest environments. Our seamless stainless steel tube meets ASTM A 213, ASTM A 269 and ASTM A 511 standard specificatins. We supply common grades of stainless steel such as 304/304L and 316/316L ， etc in standard tube sizes and wall thicknesses. Seamless stainless steel tubes provide a high level of strength and corrosion resistance for applications in harsh industrial environments whether hot or cold. We provide additional custom services such as tube cutting and tube polishing services to meet your specifications. Stainless steel seamless tubes, known for their corrosion resistance, high strength, and versatility, are widely used across industries. This analysis explores their key advantages, typical applications, and technical specifications, presented in an English format with a supporting table.
All of our stainless steel seamless pipes can be polished and polished. Industries served:
- Marine applications
- Food and beverage
- processing
- Pharmaceutical
- Power generation
- Chemical and petrochemical
- Mechanical and plant
- engineering
- Oil and gas, etc.
Advantages of Stainless Steel Seamless Tube
1.Corrosion Resistance
- Chemical Composition: Contains chromium (12–30%), nickel, and molybdenum, forming a passive oxide layer (Cr₂O₃) that resists oxidation and chemical attacks.
- Performance: Withstands acidic/alkaline environments, making it ideal for chemical processing and marine applications.
2. High Strength and Durability
- Pressure Rating: Supports high-pressure systems (e.g., 321-grade tubes rated for up to 10,000 PSI in heat exchangers).
- Temperature Range: Operates from -196°C to 800°C, depending on grade (e.g., 347 for elevated temperatures).
3. Hygienic Properties
- Surface Finish: Smooth inner walls (e.g., polished to 800#) prevent bacterial growth, compliant with FDA/EPA standards for food and pharmaceutical use.
4. Mechanical Versatility
- Formability: Cold-drawn processes enable precise tolerances (e.g., ±0.08mm OD, ±10% WT) for aerospace and automotive components.
- Weight Efficiency: High strength-to-weight ratio reduces material costs in structures like drilling rigs.
