Products Description

Our Advantages

1. Excellent Mechanical Strength

Our Cold Drawn Seamless Stainless Steel Tube is manufactured using advanced cold-drawing technology, possessing excellent tensile strength, yield strength, and fatigue strength. They undergo rigorous mechanical performance testing, enabling stable operation under high pressure and frequent mechanical cycles, making them suitable for heavy-duty machinery components.

2. High Dimensional Accuracy
Our tubes undergo strict dimensional inspection to ensure that the outer diameter, wall thickness, straightness, etc., conform to ASTM A312 standards. This reduces the need for secondary processing, ensures correct installation, and significantly improves the reliability of mechanical systems.

3. Strong Corrosion Resistance
We offer high-quality stainless steel materials such as 304/304L, 316/316L, 321, and 347, and undergo rigorous chemical composition checks to ensure compliance with EN10204 3.1 MTC certification. The tubes also undergo intergranular corrosion testing to ensure a long service life in harsh environments.

4. Surface Condition
Our tubes undergo pickling and passivation treatment, resulting in a smooth surface and the formation of a protective oxide film, thereby enhancing the tubes' corrosion resistance. Torich offers surface treatments such as polishing, BA (Brush Finish), and grinding to meet various customer application needs.

5. Packaging and Shipping

We provide multiple packaging options, including plastic caps on the pipe ends, bundling, wooden crates, or pallets, to prevent contamination or damage during transportation. We offer sea, land, and air shipping options and can provide samples.
