Rithav Pipes and Tubes, located in Delhi, India, specializes in manufacturing and supplying precision-engineered seamless tubing that meets the EN 10305‑1 and EN 10305‑4 standards. These tubes are crafted for tough industrial and fluid-power applications. The EN 10305‑1 tubing is cold-drawn for general precision tasks, while the EN 10305‑4 variant boasts tighter tolerances and ultra-smooth internal surfaces, making it perfect for hydraulic and pneumatic systems. Available in grades E215, E235, E255, and E355, these tubes come in a variety of diameters and wall thicknesses, with finishes like bright annealed (+N, NBK). Rithav is committed to maintaining strict quality standards, ensuring dimensional accuracy, and delivering promptly to support industries such as automotive, machinery, hydraulics, and instrumentation.
The EN 10305‑1 & ‑4 seamless tubes feature carbon-manganese grades: E215, E235, E255 (4‑4), and E355, with a maximum carbon content of 0.10–0.22%, silicon levels of ≤0.05–0.55%, and manganese content of ≤0.7–1.6%. Mechanical performance in the cold-drawn, normalized (+N/NBK) condition shows tensile strengths of 480 MPa for E235 and 640 MPa for E355, with elongation rates of approximately 6% and 4%, respectively. The EN 10305‑4 (domestic over mandrel) guarantees minimum yield strengths for smaller sizes and an impact toughness of at least 27 J at 0 °C. Additionally, EN 10305‑4 includes flaring, sealing, and hydraulic-pressure testing, with tighter tolerances and surface quality compared to EN 10305‑1.
