オイル&ガス デュプレックスステンレス鋼管 NACE MR0175 2205 2507 酸性サービス用
Oil and gas duplex stainless steel tubing is specifically engineered for the demanding environments encountered in upstream, midstream, and downstream operations. The unique two-phase microstructure (austenite + ferrite) combined with high chromium, molybdenum, and nitrogen content provides exceptional resistance to the corrosive conditions typical of oil and gas production, including sour service (H₂S), carbon dioxide (CO₂), chlorides, and high pressures. Our duplex tubing
ASTM A789 UNS S32750 オフショア潜水用デュプレックスステンレス鋼管
ASTM A789 UNS S32750 super duplex stainless steel tube is a premium-grade product designed for the most demanding industrial applications. With a higher chromium, molybdenum, and nitrogen content than standard duplex grades (e.g., 2205/S31803), UNS S32750 offers superior strength and exceptional corrosion resistance, particularly in aggressive chloride-containing environments. This tube is manufactured in accordance with ASTM A789, covering both seamless and welded ferritic

縫い目なし 溶接 2205 デュプレックスステンレス鋼管 ASTM A790
2205 duplex stainless steel pipe offers a balanced combination of high strength and excellent corrosion resistance, making it the preferred choice for industries such as oil & gas, chemical processing, marine engineering, and desalination plants. With a duplex microstructure (approximately 50% austenite + 50% ferrite), 2205 provides nearly twice the yield strength of common austenitic stainless steels like 304 or 316L, while maintaining good weldability and fabricability.

構造二相ステンレス鋼管 UNS S32101 低ニッケル高強度管
UNS S32101 is a lean duplex stainless steel grade that offers a balanced combination of good strength, excellent corrosion resistance, and cost-effectiveness. It belongs to the lean duplex family (also known as LDX 2101®), containing lower nickel and molybdenum than standard duplex grades like 2205, making it a more economical alternative without significantly compromising performance. Manufactured in accordance with ASTM A789 and ASTM A790, UNS S32101 tubes are available in
高圧デュプレックスステンレス鋼管 550 MPa 収力強度 耐腐蝕性
High pressure duplex stainless steel pipe is specifically designed and manufactured to withstand extreme internal pressures while maintaining structural integrity and corrosion resistance. The unique two-phase microstructure (austenite + ferrite) provides approximately twice the yield strength of standard austenitic stainless steels such as 304 and 316, allowing for significantly thinner wall sections at equivalent pressure ratings. Our high pressure duplex pipes are produced
ASTM A790 溶接式デュプレックスステンレス鋼管 2205 2507 2304
Welded duplex stainless steel pipe is manufactured by forming a flat strip of duplex stainless steel into a cylindrical shape and welding the longitudinal seam. This process produces a pipe with excellent dimensional accuracy, consistent wall thickness, and a cost-effective solution for corrosive service applications. Our welded duplex pipes are produced using advanced welding techniques including ERW (Electric Resistance Welding), EFW (Electric Fusion Welding), and DSAW
