Ống thép không gỉ song công áp suất cao 550 MPa Độ bền năng suất Chống ăn mòn
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
2507 Ống thép không gỉ siêu kép S32760 Chống ăn mòn cho dịch vụ áp suất cao
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,
Đường ống thép không gỉ kép hàn ASTM A790 hạng 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
Ống thép không gỉ song công 2205 1/8 "- 36" OD cho ngành hóa chất
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
Ống thép không gỉ song công ASTM A790 được hàn liền mạch cho các ứng dụng hàng hải dầu khí
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
Khẩu ống thép không gỉ cấu trúc képlex UNS S32101 ống cao độ bền nickel thấp
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
Kháng ăn mòn ống thép không gỉ cao độ bền
Duplex stainless steel sheet is a family of stainless steel grades with a mixed austenitic-ferritic microstructure (approximately 50% austenite / 50% ferrite). This unique structure delivers approximately twice the yield strength of standard austenitic grades like 304 or 316, combined with excellent resistance to chloride stress corrosion cracking (SCC), pitting, and crevice corrosion. Duplex stainless steel sheets are the material of choice for demanding applications in
