Refined Tube Production Method
Cold drawn seamless tube is a high-precision steel pipe material that uses cold drawn seamless tube as raw material for tolerance control and surface brightening processing.
The key feature of precision drawn tubes is their seamless construction, which allows them to withstand high pressure. The products can range from rough castings to cold drawn pieces. Precision drawn tubes are a relatively new product that has emerged in recent years, characterized by strict tolerances and surface roughness for both the inner and outer diameters.
High-purity seamless pipes feature high precision, smooth surface finish, clean inner wall, high pressure resistance without leakage, cold bending without deformation, no cracks during expansion or flattening, and can undergo various complex deformations and mechanical processing. The chemical composition of precision cold drawn pipes includes carbon (C), silicon (Si), manganese (Mn), sulfur (S), phosphorus (P), and chromium (Cr).
