ASTM A213 لوله مبادله گرما فولاد ضد زنگ مقاوم به خوردگی لوله U Bend
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
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
2205 لوله فولادی ضد زنگ ASTM A790 لوله بدون درز دوبلکس UNS S31803 / S32205 برای مواد شیمیایی دریایی
2205 Stainless Steel Pipe - UNS S31803 S32205 Seamless Tubing The 2205 duplex stainless steel pipe combines the best properties of austenitic and ferritic stainless steels. It provides excellent resistance to chloride stress corrosion cracking (SCC), high thermal conductivity, and a low coefficient of thermal expansion. Key Advantages vs Standard Austenitic Grades Higher strength - allows for reduced wall thickness and lighter weight structures Superior corrosion resistance -
لوله فولادی ضد خوردگی سوپر دوپلکس 6.0mm - 1829mm OD ASTM A790 A789 A928
Corrosion resistant duplex steel pipe is specifically engineered for service in aggressive environments where standard stainless steels such as 304 and 316 are prone to failure. The unique two-phase microstructure (austenite + ferrite) combined with elevated levels of chromium, molybdenum, and nitrogen provides exceptional resistance to a wide range of corrosive attack mechanisms. Our duplex steel pipes offer outstanding protection against pitting, crevice corrosion, stress
