لوله های بدون درز از فولاد ضد زنگ آستنیتیک کروم منگنز UNS S20100
Chrome-manganese austenitic seamless pipe is an economical alternative to traditional chromium-nickel austenitic stainless steels such as 304 and 316. This grade achieves a stable austenitic structure by substituting a portion of expensive nickel with more cost-effective manganese and nitrogen, delivering comparable mechanical properties at a significantly lower material cost. The most common chrome-manganese austenitic grade is 201 stainless steel (UNS S20100), which
لوله های بدون درز از فولاد ضد زنگ درجه دریایی
Marine grade stainless seamless pipe refers to 316 and 316L stainless steel, the industry standard for applications requiring superior corrosion resistance in chloride-rich and marine environments. The addition of 2-3% molybdenum distinguishes this grade from 304, providing significantly enhanced resistance to pitting, crevice corrosion, and stress corrosion cracking in seawater, brackish water, and chemical environments. The seamless manufacturing process ensures uniform
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
لوله گرد فولاد ضد زنگ ASTM A312 304/304L/316/316L جدول 10S تا XXS
Seamless stainless steel round pipe is manufactured without any weld seam, created by extruding a solid billet through a mandrel to form a hollow tube. This process results in a pipe with uniform wall thickness, superior pressure resistance, and excellent structural integrity — making it the preferred choice for high-pressure, high-temperature, and corrosive environments. Unlike welded pipes, seamless pipes have no weak points along the longitudinal seam, offering reliable
لوله بی سیم فولاد ضد زنگ با نیکل کم برای محیط های ساختاری تزئینی خوردنی
Low-nickel stainless steel seamless tube is an economical alternative to traditional austenitic stainless steels such as 304 and 316. By reducing nickel content and increasing manganese and nitrogen, this grade achieves a balanced austenitic structure at a significantly lower material cost, making it an attractive choice for general industrial applications where extreme corrosion resistance is not the primary requirement. The most common low-nickel austenitic grade is 201
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 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 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,
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
