Product Description Product DescriptionAttributeSpecification / Typical ValueStandard & AlloyASTM B619 / ASME SB619ManufacturingLongitudinally welded (TIG or HFW)Size RangeOD 1/8″-5″ (3.2-127 mm)Chemical Composition (wt %)Ni 58.0-63.0Mechanical Properties (annealed)Tensile ≥ 827 MPa (120 ksi)Physical PropertiesDensity 8.44 g/cm3Corrosion & Heat RangeResistant to chloride SCC, pitting & crevice corrosionTesting & Certification100 % ET / UT / hydro 1.5×PNProduct Advantages? Superior corrosion resistance - withstands oxidizing & reducing acids, seawater, chloride SCC .? High-temperature strength - retains ≥ 120 ksi tensile up to 982 °C without creep failure.? No post-weld heat treatment - low carbon + niobium stabilization prevents sensitization.? Cost-effective welded construction - lighter wall vs. seamless equals lower material & freight cost.? Wide dimensional flexibility - from 3.2 mm OD coils to 127 mm OD headers.? Proven field track record - decades of success in chemical, offshore, nuclear and aerospace sectors.Exported ProductsFrom the blast furnaces of North China to the quaysides of Singapore, from the LNG terminals of Qatar to the FPSO decks off Brazil, our steel travels the world in a single, seamless journey. We export ASTM B167 Inconel 600 seamless tubes that withstand 300 °C sour gas, EEMUA 144/234 Cu-Ni pipes that keep seawater systems corrosion-free for half a century, and ISO 2531 K9 ductile-iron pipes that anchor ballast lines beneath 200 000-ton hulls. Every heat is certified ABS, DNV or Lloyd's; every bundle is zinc-coated, plastic-capped and crated for 12 000 km of salt-spray. Our 90-10 copper-nickel coils arrive in Rotterdam coiled like giant springs, our stainless-steel seamless tubes sit ready in Houston stockyards, and our alloy-steel line pipes span deserts and deep-sea trenches alike. Wherever the ocean meets industry, our steel is already there-welded, bent, and tested-carrying water, fuel, and lifeblood to the vessels and platforms that power the planet.Technological Process1. Raw Material ├─ 99.9 % Cu cathode ├─ Ni ≥ 99.8 % └─ Fe & Mn additives2. Vacuum Melting └─ 1280 °C → composition locked (Cu 90 %, Ni 10 %, Fe 1.3 %, Mn 0.6 %)3. Casting └─ Horizontal continuous casting → ?150-400 mm hollow billet4. Hot Working ├─ Heat 850-950 °C ├─ Hot extrusion → hollow shell └─ Pilger hot-rolling (50-60 % reduction)5. Cold Working ├─ Cold drawing / cold pilgering ├─ 20-30 % wall reduction per pass └─ Multiple passes with intermediate anneal6. Bright Annealing └─ 593-816 °C, N2/H2 atmosphere7. Finishing ├─ Straightening & cutting (6 m / 12 m) ├─ End beveling or threading └─ Polishing / pickling & passivation8. Non-Destructive Testing ├─ 100 % Eddy-Current (ET) ├─ Hydrostatic test 1.5 × PN └─ Expansion & flattening tests9. Packaging & Delivery ├─ PE caps & film wrap └─ Wooden crates / steel frames → sea-worthyProduct LineAt EZ Steel Industrial, we operate one of the world's most advanced steel manufacturing facilities, combining cutting-edge automation, rigorous quality control, and sustainable practices to deliver superior steel products for global industries.Key Features of Our Production Line:√ Smart Manufacturing - AI-driven process optimization with real-time monitoring (Industry 4.0 compliant) ensures 99.3% production accuracy and minimal waste.√ High-Speed Rolling Mills - Capable of processing 2,000+ metric tons daily while maintaining ±0.1mm dimensional tolerance.√ √ √ End-to-End Quality Assurance - Laser-guided inspection, spectral analysis, and 100% ultrasonic testing guarantee compliance with ASTM, EN, JIS, and GB standards.√ Eco-Conscious Production - Closed-loop water recycling and scrap-to-furnace recycling reduce carbon footprint by 30% vs. industry averages.Why Global Partners Choose Us?1.Fast Turnaround - From raw material to finished product in 72 hours (emergency orders accepted).2.Custom Solutions - Tailored alloys, sizes (0.5mm~50mm thickness), and coatings (galvanized/epoxy) for oil & gas, construction, and automotive sectors.3.Global Logistics - ISO-certified packaging + just-in-time delivery to Europe, MENA, and APAC markets.4.Trusted by Fortune 500 companies - Let's build the future of steel together.Third-Party Testing Customers Visit For years, steel products supplied by Ezsteel have been widely applied in engineering projects such as oil and gas extraction, pipeline transportation,urban pipeline network construction,building construction,coastal and port construction,food and medicine factory construction.Our partners are throughout southeast Asia,theMidle East,Europe,Africa,America,Oceania,and more than 100 countries and regions.We also provide many steel pipe products and services to the worlds top 500 petroleum and gas, EPC companies,such as:PetroChina, Schlumberger,ADNOC,NNPC,ENI, NICO,EGPC,OXY,CCED,OGDCL, PEMEX, etc. Packing &Delivery
