Steel Pipe
We focus on exporting high-quality Seamless Steel Pipes (无缝钢管) across various specialized types, ensuring stable access to authentic piping needed for critical operations:
- Line Pipe for Oil & Gas (管线管 – OOG): High-grade piping (e.g., API 5L Gr.B, X52/X65) for reliable energy transmission.
- Boiler & Pressure Tubes (锅炉/压力管): Specialized tubes (e.g., ASTM A192/A335, DIN 17175) engineered for high-temperature and high-pressure service.
- Precision Steel Tubes (精密钢管): High-dimensional accuracy tubes (e.g., DIN 2391/EN 10305-1) for automotive and hydraulic applications.
- Fluid & Structural Pipes (流体/结构管): Versatile piping for fluid transport and structural construction projects.
