ASTM A790 لوله های دو لایه ای از فولاد ضد زنگ ، درجه 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
ASTM A790 لوله های فولاد ضد زنگ دوگانه بدون درز برای کاربردهای دریایی گاز نفت
ASTM A790 duplex stainless steel pipe is manufactured in accordance with the American standard for seamless and welded ferritic-austenitic duplex stainless steel pipe. This specification covers pipe intended for general corrosive service, with particular emphasis on applications requiring high strength and excellent resistance to pitting, crevice corrosion, and stress corrosion cracking. Our ASTM A790 duplex pipes are available in standard duplex grades (2205), super duplex
2507 لوله فولاد ضد خوردگی S32760 ضد خوردگی برای خدمات با فشار بالا
2507 super duplex stainless steel pipe is a high-performance duplex grade with a two-phase microstructure consisting of approximately 50% austenite and 50% ferrite. It belongs to the super duplex family and offers exceptional strength combined with outstanding corrosion resistance. With a Pitting Resistance Equivalent Number (PREN) exceeding 41, 2507 provides superior resistance to pitting, crevice corrosion, and stress corrosion cracking in the harshest environments,
2205 لوله دوگانه فولاد ضد زنگ 1/8 " - 36" OD برای صنعت شیمیایی
Duplex stainless steel pipe for the chemical industry is specifically engineered to withstand the aggressive corrosive environments, high pressures, and elevated temperatures commonly encountered in chemical processing facilities. The unique two-phase microstructure (austenite + ferrite) combined with high chromium, molybdenum, and nitrogen content provides exceptional resistance to a wide range of organic and inorganic chemicals. Our duplex pipes are widely specified for
لوله های فولاد ضد زنگ دوگانه با قدرت بالا لوله های ضد خوردگی روغن و گاز
Duplex stainless steel pipe is manufactured from a family of stainless steels with a two-phase microstructure consisting of approximately equal parts of austenite and ferrite. This unique structure provides a combination of high strength and excellent corrosion resistance that exceeds standard austenitic grades like 304 and 316.Our duplex stainless steel pipes offer superior resistance to stress corrosion cracking, pitting, and crevice corrosion, making them ideal for
لوله فولاد ضد زنگ دوگانه با فشار بالا 550 MPa مقاومت در برابر خوردگی
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
2205 لوله های لوله های فولاد ضد زنگ دوگانه با قدرت بالا برای کاربردهای نفت و گاز
2205 duplex stainless steel pipe is a nitrogen-enhanced duplex grade with a two-phase microstructure consisting of approximately 50% austenite and 50% ferrite. This balanced structure provides approximately twice the yield strength of standard austenitic stainless steels such as 304 and 316, combined with excellent corrosion resistance. 2205 is the most widely used duplex stainless steel grade, offering an exceptional combination of high strength, good weldability, and
S32750 لوله فولاد ضد زنگ فوق دوگانه ASTM A790 مقاومت مکانیکی بالا
S32750 Super Duplex Tube ASTM A790
لوله های فلز ضد زنگ دوگانه ساختاری UNS S32101 لوله های نیکل پایین با قدرت بالا
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
