Samia Pipes, a top-notch manufacturer and supplier based in Tunis, Tunisia, specializes in high-quality Alloy 20 Pipes that are designed to withstand harsh chemical environments with remarkable corrosion resistance and durability. These pipes are well-regarded for their ability to resist strong acids, chloride stress corrosion, and oxidizing conditions, making them a popular choice in the chemical processing, pharmaceutical, and petrochemical sectors. Samia Pipes is committed to precise manufacturing, rigorous quality control, and adherence to international standards, ensuring that their piping solutions are both reliable and high-performing. With a perfect blend of strength, longevity, and safety, these pipes are ideal for critical applications where traditional stainless steels might not hold up.
Alloy 20 Pipes are crafted from a nickel-iron-chromium alloy, enhanced with 2–3% copper and 2–3% molybdenum to boost corrosion resistance. The typical composition includes: Nickel (32–38%), Chromium (19–21%), Iron (Balance), Copper (2–3%), Molybdenum (2–3%), along with trace amounts of carbon, manganese, and silicon. This unique blend provides outstanding resistance to sulfuric acid, nitric acid, and chloride environments. On the mechanical side, Alloy 20 Pipes boast a tensile strength ranging from 485 to 690 MPa, a yield strength of about 170 to 310 MPa, and good elongation (30–40%). They also demonstrate excellent toughness, weldability, and formability while maintaining their shape under high temperatures.
