Stainless Steel Welded Tube

Stainless Steel Welded Tube is manufactured by rolling flat stainless steel strips or coils into tubular shapes and then welding them. Electric Resistance Welding (ERW) and TIG welding are commonly used. These tubes offer corrosion resistance, high-temperature resistance, and a high surface finish. They are commonly used in industries such as food and beverage, chemical processing, and construction, as well as structural components, automotive exhaust systems, and medical devices.

Products Description

Our Advantages

1. Delivery Capabilities
TORICH has its own stainless steel factory, with stable production capacity and inventory, ensuring high-volume delivery.

2. High Dimensional Accuracy
Each piece of our stainless steel welded tube undergoes dimensional measurement and wall thickness uniformity testing to ensure dimensional tolerances meet standard requirements and uniform wall thickness.

3. Excellent Corrosion Resistance
The tubes undergo pickling and passivation treatment to enhance their corrosion resistance. They can be used in applications such as automotive exhaust and heat exchangers.
Each piece of our tube undergoes intergranular corrosion testing and pitting corrosion testing to ensure corrosion resistance.

4. Weld Quality
Our stainless steel welded tubes undergo hydrostatic pressure testing to ensure they are leak-free. The surface of the tubes undergoes pickling and passivation, bright annealing, and polishing to ensure smooth welds and the removal of internal weld beads.

Steel Grade

304 / 304L: The most widely used stainless steel grade for welded tubes offering good corrosion resistance and formability.
316 / 316L: Offers improved corrosion resistance especially against chlorides and marine environments.
321: Titanium-stabilized grade for high temperature resistance and reduced risk of intergranular corrosion.
Duplex Stainless Steel: Combines austenitic and ferritic structures for higher strength and improved corrosion resistance, often used in chemical and offshore industries.

Possible Alternative Grades

Alternatives to standard grades include low carbon (L grades) for improved weldability, super-austenitic grades (e.g., 254 SMO) for extreme corrosion resistance, ferritic grades (e.g., 430) for magnetic applications, and nickel-based alloys for very aggressive environments. Selection depends on corrosion resistance needs, mechanical requirements, and cost considerations.
