スーパーデュプレックス 2507 不同鋼板 ASTM A240 高強度耐腐食性
ASTM A240 Super Duplex 2507 (UNS S32750) is a high-strength, corrosion-resistant stainless steel plate with a ferritic-austenitic microstructure. It offers approximately three times the yield strength of 316L and a PREN value of 40 or higher, providing exceptional resistance to pitting, crevice corrosion, and chloride stress corrosion cracking. Ideal for the most demanding environments, Super Duplex 2507 is widely used in offshore platforms, chemical processing, seawater
ASTM A789 熱交換器計装ライン用シームレス溶接 SS 精密パイプ
ASTM A789 2205 油圧プロセスライン用二重シームレスチューブ耐食性
ステンレス鋼の二重管 2205 2507 冷たい引き出しシームレス管
Seamless duplex stainless steel tube is manufactured without any weld seam, produced by extruding a solid billet of duplex stainless steel into a hollow tube through a piercing and rolling process. The absence of a weld seam provides superior strength, uniform wall thickness, and excellent performance under high pressure, high temperature, and corrosive conditions. Our seamless duplex tubes offer the unique combination of high strength (approximately twice that of austenitic
ASTM A213 ステンレス鋼熱交換管 耐腐蝕型Uベンドパイプ
U-bend stainless steel heat exchanger tubes are seamless or welded tubes precision-formed into a U-shape, designed specifically for shell and tube heat exchangers. This U-configuration allows the tube bundle to expand and contract freely under thermal stress while eliminating the need for a second tube sheet, making the entire heat exchanger more compact, cost-effective, and easier to maintain. Manufactured from high-quality austenitic stainless steel grades such as 304, 304L
