It resists pitting, crevice corrosion and chloride stress corrosion cracking.2.Biological fouling inhibitionThe release of trace copper ions can inhibit the attachment of algae and shellfish, reducing the cleaning cycle by more than 70%.3.High mechanical strengthThe tensile strength of the annealed state is ≥303 MPa, the yield strength is ≥110 MPa, and the elongation is ≥42%. It meets the high water pressure and impact load requirements of ships.4.Wide temperature rangeContinuous operation from -196 °C to +300 °C, suitable for low-temperature pipelines of LNG ships and heat oil heat exchange conditions.5.Excellent thermal conductivityThe thermal conductivity is 26 W/m·K, approximately 3 times higher than stainless steel, improving the heat exchange efficiency of condensers and coolers.6.Easy welding and processingTIG/MIG welding can be performed without preheating or post-heating, with a joint strength coefficient of ≥0.9. On-site installation is 30% faster.7.Comprehensive standard systemIt is in line with ASTM B111, BS 2871, CN102, GB/T 8890 BFe10-1-1, EEMUA 144/234, and has complete classification society certifications from ABS/DNV/LR.8.Low life cycle costThe initial investment is slightly higher than stainless steel, but it eliminates cathodic protection and frequent maintenance, resulting in a total cost savings of ≥30% over 30 years.Exported Products From 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
