SS304 Polished Tubes for Fire Protection Systems

Henan Bebo is a professional manufacturer of SS304 polished tubes.
Our Core Product Competitiveness
As a professional manufacturer, we are not just "selling tubes"; we are providing a precision manufacturing service.
1. Strict Raw Material Control:
We only use high-quality 304 grade A materials from leading domestic manufacturers (such as TISCO and Baosteel) to ensure stable and compliant nickel and chromium content (Ni>8%, Cr>18%), eliminating the risk of rust and cracking caused by "secondary materials" and "recycled materials" from the source. We can provide material certificates.
2. Exquisite Polishing Process:
We offer a variety of polishing grades to meet the needs of different application scenarios:
Mechanical Polishing (MP): Suitable for general decoration and structural tubes, with a smooth, bright white surface.
Electropolishing (EP): Suitable for complex shaped fittings, it can achieve consistent finish on both inner and outer walls, with better passivation effect, especially suitable for medical devices and semiconductor industries.
Our surface roughness (Ra value) can be precisely controlled, from Ra ≤ 0.8μm (smooth surface) to Ra ≤ 0.4μm or even lower mirror-finish effects, we can consistently achieve.
3. Comprehensive Quality Inspection System:
Inner Wall Inspection: Use an endoscope to ensure uniform inner wall polishing without any defects.
Surface Inspection: Strictly inspect the outer surface under standard lighting to ensure no scratches, no pitting, and no polishing marks.
Passivation Treatment: Pickling and passivation treatment are performed before leaving the factory to further enhance corrosion resistance.
4. Flexible Customization and Service Capabilities:
Complete Specifications: A large inventory is available in the range of outer diameter Φ6mm - Φ219mm and wall thickness 0.5mm - 5.0mm, which can be supplied quickly.
Customized Cutting: We can provide precise fixed-length cutting according to your requirements, reducing your processing steps and material loss.
