Sumer Metal Industries Private Limited manufactures, supplies and exports premium Super Duplex Stainless Steel S32750 U-Tubes engineered for the most demanding corrosion and pressure applications. Our S32750 U-tubes combine the high strength of duplex microstructures with exceptional resistance to pitting, crevice and chloride stress-corrosion cracking, making them a preferred choice for oil & gas, desalination, chemical processing and marine installations. We produce U-tube bundles and finished U-tube assemblies in controlled heat-treated conditions to ensure consistent duplex microstructure and properties.
As an established exporter, Sumer Metal Industries ships S32750 U-tubes to clients across Oman, Qatar, Saudi Arabia, the UAE, Kuwait, Spain, Germany, the USA, Canada and several regions across Africa—meeting international documentation and inspection requirements (EN/ASTM/NACE as required). Our quality system includes full traceability (heat number to test certificate), PMI/optical emission test reports on request, and third-party inspection when specified by the buyer. We tailor length, U-bend geometry and end-preparations to customer drawings and can supply material with mill or third-party certifications.
S32750 (often referred to by its commercial name Duplex 2507 / Super Duplex 2507) achieves its performance through a high chromium-molybdenum-nitrogen chemistry combined with balanced ferrite/austenite phases. This chemistry produces a very high PREN (pitting resistance equivalent number, typically ≥40 for S32750), which translates to excellent resistance in chloride-bearing, high-temperature and sour environments. Its high yield strength also enables lighter, thinner designs compared with austenitic grades for equivalent mechanical performance.
Typical mechanical attributes for S32750 U-tubes include very high yield and tensile strengths (yield commonly around ≥550 MPa and tensile ~795 MPa / 116 ksi, with minimum elongation ~15%), plus good toughness at ambient and sub-zero temperatures. These properties make S32750 suitable for high-pressure heat exchanger duties where thermal cycling and chlorides are present; however the alloy is not recommended for prolonged use above approximately 300–350°C without consultation due to phase stability limitations. Always review service temperature, chloride concentration and fabrication history when selecting S32750 for U-tubes.
