KS D3564 Carbon Steel Pipe Introduction
KS D3564 seamless steel pipe is produced according to Korean KS D3564 standard. It is formed by perforating and rolling a whole piece of steel billet without welds. It is commonly used in conveying pipelines, mechanical components and building structures.
KS D3564 Carbon Steel Pipe Advantage
High Strength
KS D3564 seamless steel pipe is formed from high-quality carbon steel billets through hot rolling. Its tensile strength typically exceeds 410 MPa and its yield strength is no less than 245 MPa. It is resistant to deformation or cracking when subjected to high pressure and external impact.
Precise Dimensional Tolerances
During the rolling process, CNC equipment precisely controls the roll pressure and mandrel position of KS D3564 seamless steel pipe, ensuring a wall thickness and outer diameter tolerance of no more than 0.5 mm, ensuring a perfect fit during installation.
Excellent Corrosion Resistance
KS D3564 seamless steel pipe is pickled to remove the oxide scale and passivated to form a dense protective film, which can effectively isolate corrosive media such as moisture, oxygen and chloride ions from contacting the internal steel and prevent surface rust.
