Product Description
Full Grade Range Steel Pipe
🛡️ Full Grade Range 201 to 904L Steel Pipe for Heat Exchanger Manufacturing

Our full range of stainless steel pipes provides tailored corrosion and temperature resistance for various service conditions, from general use (304) and chloride service (316L) to high temperatures (321) and severe acids (904L). Manufactured to ASTM standards in seamless or welded forms, they offer precise dimensions and efficient heat transfer.

Economical/General Purpose (201, 304/L):

201 uses Manganese and Nitrogen for cost-efficiency. 304/304L offers excellent general corrosion resistance in oxidizing environments.

Molybdenum-Enhanced (316/L, 317L):

Significantly improves resistance to pitting and crevice corrosion in chloride environments like brackish water.

Inspecting & Quality Control

Stabilized & High-Temperature Grades (321, 347): Stabilized with Titanium or Niobium to prevent chromium carbide precipitation during high-temperature exposure.

Premium Corrosion-Resistant Alloy (904L): Outstanding performance in sulfuric and phosphoric acids with a high Pitting Resistance Equivalent Number (PREN >33).

Packing & Delivery
Production Workshop

Professional & Comprehensive: Equipped with state-of-the-art machinery and automated production lines, integrating precision engineering with strict quality control.

🌱 Modern & Sustainability-Focused: Utilizing eco-efficient processes to produce steel pipes that perform under pressure while reducing environmental impact.
