Material Selection Guide
Duplex 2205 Grade
The most widely used workhorse grade offering excellent balance of high strength and corrosion resistance for demanding applications.
Super Duplex 2507 Grade
Enhanced chromium, molybdenum and nitrogen content provides superior strength and corrosion resistance, ideal for extreme chloride and acid environments.
Polished Surface Benefits
Our precision polished surface treatment creates a high-finish exterior that reduces media adhesion and bacterial growth while enhancing cleaning efficiency. The process also strengthens the material's passivation film, improving overall corrosion resistance and system purity.
Industry Applications
These seamless tubes are specifically designed for corrosive media transport in chemical processing (acids, alkalis, chloride solutions), oil & gas (wet gas, production fluids), and desalination systems where seawater corrosion resistance is critical.
Quality Assurance
Our comprehensive three-step inspection system ensures product reliability:
- Incoming material composition verification
- Dimensional and surface control during production
- 100% final inspection of each finished pipe
All products undergo non-destructive testing including PMI chemical analysis, eddy current or hydrostatic flaw detection to guarantee full ASTM A789 compliance.
Manufacturing Excellence
With 19 years of seamless pipe production experience and over 3,000 tons of stainless steel inventory, we ensure fast delivery of regular sizes within two weeks. Our one-stop procurement service includes pipe fittings and flange products for complete piping system solutions.
