Bereket Pipes, a top-notch manufacturer and supplier located in Addis Ababa, Ethiopia, specializes in high-quality Stainless Steel 317 and 317L EFW Pipes that are built to excel in harsh, corrosive, and high-temperature settings. These pipes are crafted using cutting-edge Electric Fusion Welding (EFW) technology, which guarantees precise dimensions, a smooth surface finish, and robust weld integrity. Renowned for their exceptional resistance to chemical corrosion and oxidation, the Stainless Steel 317 and 317L EFW Pipes from Bereket Pipes are perfect for demanding sectors like chemical processing, petrochemical, marine, and food processing, where reliability, durability, and corrosion resistance are absolutely essential.
The composition of Stainless Steel 317 and 317L EFW Pipes includes 18–20% chromium, 11–15% nickel, and 3–4% molybdenum, along with carefully controlled amounts of carbon, manganese, and silicon. This unique alloy mix offers outstanding resistance to pitting, crevice corrosion, and acidic conditions. With a tensile strength of around 515 MPa, yield strength of 205 MPa, and elongation rates between 35–40%, these pipes are built to last. The low-carbon 317L variant enhances weldability and minimizes carbide precipitation, ensuring excellent toughness and structural stability even when faced with high temperatures and pressures.
