Samia Pipes, a prominent manufacturer and supplier located in Tunis, Tunisia, specializes in providing top-notch Stainless Steel 317/317L Heat Exchanger Tubing. This tubing is designed to meet the rigorous demands of various industries, including petrochemical, power generation, and marine processing, on a global scale. Engineered for outstanding corrosion resistance, these tubes excel in environments that face harsh acids, chlorides, and elevated temperatures. Adhering to ASTM A213/A249 standards, Samia Pipes guarantees remarkable dimensional accuracy, mechanical strength, and thermal performance. They offer customized solutions with both seamless and welded tubing options, making them perfect for critical heat transfer applications in corrosive and high-pressure settings.
Stainless Steel 317/317L Heat Exchanger Tubing is a high-alloy austenitic stainless steel known for its superior corrosion resistance. Its typical chemical makeup features 18–20% chromium, 11–15% nickel, 3–4% molybdenum, and a low carbon content (≤0.03%) in 317L, which enhances weldability and minimizes sensitization. The mechanical properties include a tensile strength ranging from 515–620 MPa, a yield strength of 205 MPa, and a minimum elongation of 30%. These tubes are highly resistant to pitting, crevice corrosion, and stress corrosion cracking, making them ideal for aggressive chemical environments and high-efficiency heat exchanger systems.
