Rithav Pipes and Tubes stands out as a leading manufacturer and supplier of top-notch Cold Drawn Seamless (CDS) Tubing based in Delhi, India. We take pride in crafting precision-engineered CDS tubes that boast remarkable dimensional accuracy, a smooth surface finish, and outstanding mechanical strength. Our cold drawn seamless tubing is produced using cutting-edge processes designed to meet the rigorous demands of critical industrial applications. At Rithav Pipes and Tubes, we are dedicated to delivering reliable, high-performance tubing solutions for various sectors, including automotive, hydraulics, construction, and engineering, both in India and around the world.
Typically, CDS Tubing is crafted from carbon steel, alloy steel, or stainless steel, with compositions that may include elements like carbon (up to 0.35%), manganese (up to 1.65%), silicon, and other trace elements depending on the specific grade (like SAE 1018, ST52, etc.). It offers impressive tensile strength (up to 800 MPa), excellent yield strength (up to 600 MPa), and remarkable elongation properties (≥10%). These tubes are recognized for their uniform grain structure, tight tolerances, and enhanced hardness, making them perfect for high-pressure and load-bearing applications.
