Rithav Pipes and Tubes, a trusted manufacturer and supplier located in Delhi, India, specializes in high-quality Carbon Steel DIN 17121 Pipes, crafted specifically for structural applications in line with the German standard DIN 17121. These pipes are a go-to choice in civil engineering, industrial construction, and machinery, thanks to their remarkable strength, formability, and precise dimensions. Available in various grades like St37.2, St44.2, and St52.3, they come in different wall thicknesses and lengths to meet a wide range of application requirements. Rithav is committed to quality and performance, conducting rigorous testing to ensure durability, weldability, and resistance to mechanical stress in structural settings.
JIS G3455 Pipes are generally constructed from high-strength carbon steel, featuring a chemical makeup that includes carbon (≤0.35%), manganese (0.30–1.30%), and minimal phosphorus and sulfur (≤0.035%). These pipes boast a minimum tensile strength of 410–610 MPa and a yield strength of around 245–355 MPa, depending on the grade and heat treatment. Their seamless design and pressure-tested reliability make them ideal for high-pressure applications. Renowned for their excellent machinability, good weldability, and resistance to cracking, these pipes can also be heat-treated to further boost their mechanical performance.
