Cold Drawn Seamless Tubes (CDS) are widely utilized in applications that demand exceptional strength and resistance to high pressure. In comparison to hot-finished seamless tubes, CDS offers tighter tolerances and superior mechanical properties, making them ideal for mechanical use. These tubes are particularly favored in the hydraulic industry for manufacturing chrome-plated telescopic cylinders and hydraulic rods. Additionally, they are commonly employed in the production of large-diameter, thick-walled, high-pressure hydraulic cylinders. Cold drawn seamless tubes are also integral to the manufacturing of heavy-duty equipment, including cranes and garbage trucks. Below is a detailed size chart for cold drawn seamless tubes.
