Products Description

our Advantages

1. Corrosion Resistance

The TP304 U Bend Stainless Steel Tube is made from high-quality TP304 stainless steel, ensuring a long service life in humid, mildly acidic, and industrial environments.
The raw materials used by TORICH undergo strict chemical composition control to ensure compliance with ASTM A688 TP304 standards.

2. U-Bend Quality

Our tubes are solution annealed after bending to eliminate residual stress caused by bending and restore the corrosion resistance of the U-bend area.
The TP304 U Bend Stainless Steel Tube is manufactured using a cold bending process with controlled bending radius, ensuring uniform wall thickness in the bending area and undergoing non-destructive testing to ensure no internal defects.

3. Surface Quality

Our stainless steel bent tubes undergo pickling, passivation, and polishing treatments to ensure smooth inner and outer surfaces, free from scale, burrs, or scratches. Ultrasonic cleaning is available for high-purity applications.
TORICH's U-bend tubes undergo rigorous microscopic inspection, eddy current testing, and surface roughness measurement to ensure compliance with ASTM A688 standards.

4. High Dimensional Accuracy

After bending, the tubes are straightened to ensure that the bending radius and straightness meet standard specifications or customer requirements.
The tubes undergo strict dimensional inspection, with outer diameter tolerances strictly controlled to ±0.05mm, ensuring efficient assembly in heat exchanger, condenser, and boiler applications.
