لوله های فولاد ضد زنگ با قدرت بالا ASTM A789 مقاوم در برابر خوردگی
ASTM A789 / A789M covers the requirements for seamless and welded duplex stainless steel tubes for general corrosion-resistant service, with particular emphasis on resistance to stress corrosion cracking. This product combines the excellent toughness of austenitic stainless steel with the high strength of ferritic stainless steel, while offering superior resistance to chloride-induced pitting and crevice corrosion. This product covers common grades including UNS S31803,
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
لوله بدون درز ASTM A312 304L از جنس استنلس استیل UNS S30403 Cold Drawn Annealed Pickled
304L Stainless Steel Seamless Pipe 304L (UNS S30403) is the most widely used low-carbon austenitic stainless steel globally. With its carbon content controlled below 0.03%, 304L Stainless Steel Seamless Pipe effectively prevents intergranular corrosion after welding, making it an ideal choice for chemical, petroleum, and pharmaceutical industries requiring highly reliable welded structures. Our seamless tubes strictly adhere to the ASTM A312 standard, manufactured using cold
201 لوله بی سیم از فولاد ضد زنگ ASTM A554 SS لوله بی سیم با نرخ سخت شدن کار بالا
201 Stainless Steel Seamless Pipe ASTM A554 SS Tube with Mill Test Certificate The 201 Stainless Steel Seamless Pipe is an austenitic chromium-nickel-manganese alloy that provides an economical solution for moderately corrosive environments. Compared to standard carbon steel, it delivers superior oxidation resistance and significantly higher mechanical strength. At ZhongCheng, we manufacture these pipes in strict accordance with ASTM A554 / A312 standards, ensuring precise
ASTM A789 2205 لوله های دقیق فولاد ضد زنگ دوگانه مقاوم در برابر خوردگی
ASTM A789 2205 لوله بدون درز دوبلکس مقاوم در برابر خوردگی برای خطوط فرآیند هیدرولیک
UNS S31803 لوله بدون درز ASTM A789 4 "جدول 40 لوله فولاد ضد زنگ
UNS S31803 duplex stainless steel pipe is a widely used duplex grade that offers a balanced mix of good strength, excellent corrosion resistance, and cost-effectiveness. It is the original standard duplex stainless steel, commonly specified in ASTM A790 and ASTM A789 for both seamless and welded pipe applications.With a dual-phase microstructure (austenite + ferrite), UNS S31803 provides approximately twice the yield strength of 304 or 316L austenitic stainless steels, while
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
TP304 TP316 لوله بدون درز از فولاد ضد زنگ برای سرویس مقاوم به خوردگی با فشار بالا
ASTM A312 seamless stainless steel pipe is manufactured in accordance with ASTM A312 / ASME SA312, specifically designed for high-pressure and corrosion-resistant applications. The seamless construction eliminates the weld line, providing uniform strength, superior reliability, and excellent performance in demanding environments. This product is available in TP304 and TP316 grades, offering a balance of cost-effectiveness and enhanced corrosion resistance. It is widely used
316 316L فولاد ضد زنگ لوله بدون درز آستنیتی نیکل فولاد آلیاژی کروم مولیبدن
316/316L Seamless Pipe - ASTM A312 TP316L Marine-grade Stainless Steel Pipe 316/316L stainless steel seamless pipe is an austenitic chromium-nickel-molybdenum alloy pipe known for its superior corrosion resistance, especially against chlorides and acidic environments. 316L is the low-carbon version of 316, offering better weldability and resistance to intergranular corrosion after welding. Both grades are widely used in marine, chemical, and pharmaceutical applications. Key
