ASTM A249 ASME SA249 لوله های فولاد ضد زنگ جوش شده برای مبادلات گرما
Welded stainless steel tube is manufactured by forming stainless steel strip into a tube shape and longitudinally welding the seam using automatic GTAW (Tungsten Inert Gas) or laser welding processes. After welding, the tube undergoes solution annealing and NDT testing to ensure weld integrity and consistent corrosion resistance. Welded tubes offer a cost-effective alternative to seamless tubes for applications not requiring the extreme pressure ratings or critical service
ASTM A789 UNS S32750 لوله های فولادی ضد زنگ دوگانه برای زیردریایی دریایی
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
ASTM A249 لوله ای از فولاد ضد زنگ آستنیتیک جوش برای خدمات دیگ گرمایی
ASTM A249 / A249M is a standard specification issued by ASTM International for welded austenitic stainless steel tubes used in boilers, superheaters, heat exchangers, condensers, and hydraulic systems. These tubes are manufactured using GTAW or ERW processes and are supplied in the solution annealed condition to ensure corrosion resistance and high-temperature strength. This product covers common grades such as TP304, TP304L, and TP304H, making it particularly suitable for
لوله بدون درز از فولاد ضد زنگ SS 310 با دمای بالا برای خدمات گرمای شدید
SS 310 pipe is an austenitic stainless steel grade specifically designed for high-temperature applications. With excellent oxidation resistance and good strength at elevated temperatures, this grade is the preferred choice for furnace parts, heat treatment equipment, and high-temperature industrial piping systems. The 310 grade contains high levels of chromium (24-26%) and nickel (19-22%), which provide exceptional resistance to scaling at temperatures up to 1100°C (2012°F)
لوله فولاد ضد زنگ 310S با کربن پایین و دمای بالا برای خدمات گرمای مداوم
310S pipe is a low-carbon version of the standard 310 stainless steel grade, specifically designed for continuous high-temperature service where prolonged exposure to elevated temperatures is required. The lower carbon content (0.08% maximum compared to 0.25% for standard 310) provides improved weldability and reduces the risk of carbide precipitation during welding or sustained high-temperature operation. Like its standard 310 counterpart, 310S contains high levels of
1.4307 لوله بدون درز فولادی ضد زنگ EN DIN درجه آستنیتی کم کربن
1.4307 seamless stainless pipe is the European (EN/DIN) designation for a low carbon austenitic stainless steel grade, equivalent to UNS S30403 and ASTM A312 TP304L. This grade is specifically designed for applications requiring excellent corrosion resistance combined with superior weldability, particularly where post-weld heat treatment is not practical or desired. The "1.4307" designation follows the EN 10088 and EN 10216-5 standards, which govern seamless stainless steel

لوله دوبلکس فولاد ضد زنگ 2205 2507 لوله بدون درز سرد کشیده
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
دقت بالا 304 فولاد ضد زنگ لوله بی سیم مقاوم در برابر خوردگی سرد رول
304 Stainless Steel Seamless Pipe The 304 stainless steel seamless pipe is a globally recognized standard grade in the stainless steel family. With a chemical composition of 18% chromium and 8% nickel, it offers excellent corrosion resistance, high toughness, and outstanding formability. Manufactured using precision seamless cold-rolling technology, this pipe delivers a superior surface finish, tight dimensional tolerances, and consistent mechanical properties — making it the
