1.4404 لوله های بی سیم فولاد ضد زنگ مقاومت در برابر کلرید اسید
1.4404 seamless stainless pipe is the European (EN/DIN) designation for low carbon, molybdenum-bearing austenitic stainless steel, equivalent to UNS S31603 and ASTM A312 TP316L. This grade is specifically designed for applications requiring superior corrosion resistance combined with excellent weldability, particularly where post-weld heat treatment is not practical or desired. The "1.4404" designation follows the EN 10088 and EN 10216-5 standards, which govern seamless
UNS S30403 لوله بدون درز از فولاد ضد زنگ TP304L قابل جوش بدون درمان حرارتی پس از جوش
UNS S30403 seamless pipe is a low carbon version of the standard 304 austenitic stainless steel, designed for applications requiring enhanced resistance to intergranular corrosion after welding or elevated temperature exposure. The "UNS S30403" designation corresponds to the Unified Numbering System for metals, identifying a composition of 18-20% chromium and 8-12% nickel, with a maximum carbon content of 0.030%. The low carbon content is the defining characteristic of UNS
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
لوله گرد فولاد ضد زنگ پردازش گرم 304 304L 310S 321 لوله بدون درز داغ
Hot processed stainless steel round tube refers to seamless tubing manufactured through hot forming operations, where solid stainless steel billets are heated to approximately 1200°C (2190°F) and then pierced, rolled, and elongated to achieve the desired dimensions. This manufacturing method produces a tube with no longitudinal weld seam, offering uniform mechanical properties, consistent wall thickness, and superior pressure-holding capability. The hot processing method –
2205 لوله گرد فولاد ضد زنگ UNS S32205 بدون درز برای کاربردهای دریایی نفت و گاز
2205 stainless steel round tube is a high-strength, highly corrosion-resistant specialty pipe material. Its microstructure consists of approximately 50% ferrite and 50% austenite in a duplex configuration. This unique microstructure gives it nearly twice the yield strength of ordinary stainless steel, while also exhibiting excellent resistance to stress corrosion cracking in chloride ion environments.Compared to 304 and 316L austenitic stainless steels, 2205 can withstand
ASTM A312 SA312 لوله های بی سیم از فولاد ضد زنگ مقاوم در برابر اسید برای پردازش شیمیایی
The ASTM A312 Pipe for Chemical Processing is manufactured in accordance with the internationally recognized ASTM A312 standard, which specifies seamless, straight-seam welded, and heavily cold-worked welded austenitic stainless steel pipes. Designed specifically for high-corrosion and high-temperature service in chemical plants, this pipe offers excellent resistance to a wide range of aggressive media, including acids, alkalis, solvents, and chemical intermediates. Its
لوله دقیق فولاد ضد زنگ بدون درز کشیده شده سرد سطح روشن تحمل تنگ ± 0.03mm
Cold drawn seamless precision pipe is manufactured from solid billet through a process of piercing and cold drawing, resulting in no weld line, uniform wall thickness, and excellent dimensional accuracy. Compared to welded tubing, it offers superior pressure resistance and structural integrity, making it ideal for high-reliability applications. Key Features: No weld seam – homogeneous structure Tight tolerance: OD/ID up to ±0.03mm Smooth surface finish: Ra ≤ 0.4μm Enhanced
TP304 / TP 316L لوله دقیق فولاد ضد زنگ OD 1.6mm - 50.8mm ASTM A269
ASTM A269 precision stainless steel pipe is manufactured to the strict requirements of the ASTM A269 standard, which covers seamless and welded austenitic stainless steel tubing for general corrosion-resistant and high-temperature service. This pipe offers excellent dimensional accuracy, clean internal surfaces, and reliable mechanical properties, making it ideal for instrumentation, medical, and other precision applications. Key Features: Compliant with ASTM A269 standard
