Rithav Pipes and Tubes, based in Delhi, India, has built a solid reputation as a leading manufacturer and supplier of ASTM A335 Grade P1 Alloy Steel Seamless Pipes. These pipes are celebrated for their outstanding performance in high-temperature and high-pressure environments. Made from top-notch chromium-molybdenum alloy steel, they offer exceptional strength, durability, and resistance to thermal stress. At Rithav, we ensure our seamless pipes meet ASTM A335 standards, making them perfect for power plants, refineries, and petrochemical industries. With cutting-edge manufacturing techniques, rigorous quality control, and prompt delivery, we cater to both local and international clients, providing reliable and cost-effective piping solutions for essential industrial applications.
ASTM A335 Gr P1 Alloy Steel Seamless Pipes are primarily made up of carbon (≤ 0.10%), manganese (0.30–0.80%), phosphorus (≤ 0.025%), sulfur (≤ 0.025%), and molybdenum (0.44–0.65%). These components significantly boost the pipes’ strength and high-temperature resilience. They boast a minimum tensile strength of 380 MPa, a minimum yield strength of 205 MPa, and an elongation of at least 30%. P1 pipes are versatile, suitable for bending, flanging, and welding. Their ability to maintain mechanical integrity at elevated temperatures makes them perfect for steam, heat, and high-pressure service lines in power and process plants.
