Adopting low-carbon fine-grained steel raw materials, the pipe features excellent plasticity, strong impact resistance and stable low-temperature performance, not easy to deform under long-term cyclic working load.
Manufactured with precision cold drawing process, achieving ultra-smooth inner and outer wall, high roundness and straightness, effectively reducing pipeline fluid loss and improving delivery efficiency.
Compliant with DIN industrial standards, covering ST35.8 and ST45.8 mainstream grades. Each batch undergoes hydraulic pressure test and dimensional inspection, with complete qualification documents and export standard packaging.
