ASTM A790 รอยท่อสแตนเลสดูเพล็กซ์เกรด 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
คาร์บอนต่ํา 304L 316L 317L 321L สแตนเลส ท่อผ่าทนทานต่อการกัดกร่อน
The Low-Carbon Stainless Steel Pipe is specifically designed for welding applications where resistance to intergranular corrosion is critical. With a maximum carbon content of 0.03% (compared to 0.08% in standard grades), this pipe minimizes the formation of chromium carbides during welding, preventing sensitization and preserving corrosion resistance in the heat-affected zone (HAZ). Manufactured as seamless or welded and subsequently annealed, it offers excellent weldability
ท่อเหล็กดับเพลสความแข็งแรงสูง ท่อน้ํามันและแก๊สทนต่อการกัดกร่อน
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
2507 สูปเพลสสแตนเลส Super Duplex S32760 ป้องกันการกัดกร่อนสําหรับการใช้งานความดันสูง
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,
ASTM A500 ท่อสี่เหลี่ยมจากเหล็กไร้ขัด เกรด B ผนังสี่เหลี่ยม
What Is ASTM A500? ASTM A500 is the American standard for cold-formed welded and seamless carbon steel structural tubing in round, square, and rectangular shapes. It is the go-to specification for structural applications where strength, weldability, and economy are required. Square steel tubes under ASTM A500 are produced as cold-formed welded tubes, then heat-treated to remove internal stresses and improve mechanical properties. The standard covers four grades: A, B, C, and
ท่อเหล็กไร้ขัดสนองกัดกร่อนกลม สําหรับการใช้งานทางเคมีทางทะเล
The High Corrosion Resistance Round Pipe is engineered from premium stainless steel grades with optimized chromium, nickel, and molybdenum content to withstand aggressive environments where standard steel pipes would rapidly degrade. This pipe provides exceptional protection against rust, pitting, crevice corrosion, and stress corrosion cracking caused by chlorides, acids, alkalis, and marine atmospheres. Available in seamless or welded construction, it delivers long-term
2205 ท่อท่อเหล็กดับเพลส ความแข็งแรงสูง สําหรับการใช้งานน้ํามันและก๊าซ
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
