Irfan Pipes and Tubes, based in Istanbul, Turkey, stands out as a leading manufacturer and supplier of top-notch stainless steel piping solutions, particularly known for their Stainless Steel 904L Seamless Pipes. With a reputation for precision engineering and a strong commitment to international quality standards, the company caters to demanding industries like oil & gas, petrochemicals, pharmaceuticals, and marine sectors. Thanks to their state-of-the-art production facilities and rigorous quality control measures, Irfan Pipes and Tubes provides seamless pipes that boast exceptional strength, corrosion resistance, and longevity. Their 904L seamless pipes are specifically crafted to perform reliably in harsh and corrosive environments, ensuring both safety and efficiency.
Stainless Steel 904L Seamless Pipes are crafted from a low-carbon, high-alloy austenitic stainless steel. The blend consists of Chromium (19–23%), Nickel (23–28%), Molybdenum (4–5%), Copper (1–2%), and Carbon (<0.02%). This unique composition offers remarkable resistance to reducing acids, chloride-induced corrosion, and pitting. The seamless design not only enhances strength but also ensures uniformity. In terms of mechanical properties, these pipes have a minimum tensile strength of 490 MPa, a yield strength of 220 MPa, and an elongation of 35%. These characteristics make 904L seamless pipes perfect for high-pressure systems and corrosive applications where weld integrity and leak-proof performance are essential.
