Mirza Pipe and Tubes, located in Riyadh, Saudi Arabia, stands out as a trusted manufacturer and supplier of top-notch stainless steel piping solutions designed for high-temperature and corrosive settings. We take pride in our Stainless Steel 309S Pipes, a special austenitic stainless steel grade crafted for exceptional oxidation resistance and thermal stability. These pipes are perfect for applications in heat treatment equipment, furnaces, and the petrochemical industry, and they’re produced to meet international standards for durability, performance, and consistency. At Mirza Pipe and Tubes, we’re dedicated to precision and ensuring customer satisfaction, providing reliable piping solutions for even the most demanding industrial operations.
Our Stainless Steel 309S Pipes feature 22–24% chromium and 12–15% nickel, with a lower carbon content compared to standard 309, which enhances weldability and minimizes carbide precipitation. They offer remarkable resistance to oxidation and scaling at temperatures reaching up to 1000°C, along with impressive strength and ductility in both high and low temperature scenarios. The key benefits include outstanding heat resistance, excellent weldability, long-lasting structural integrity during thermal cycling, and good corrosion resistance in mildly corrosive and high-temperature environments. This makes them a fantastic choice for continuous service in elevated heat conditions.
