Copper Cathodes

Description

1. Product Overview
Steel Water Pipes are high-strength, corrosion-resistant tubular products engineered for the conveyance of potable water, wastewater, and raw water in critical infrastructure systems. Their primary industrial use lies in municipal water distribution, industrial process piping, and long-distance transmission lines. The key value proposition is exceptional durability under high pressure and extreme temperatures, delivering a service life exceeding 50 years with minimal maintenance. Strategically, they are indispensable for global water security and aging infrastructure renewal, where material failure is not an option.

2. Key Specifications & Technical Characteristics

• Chemical Composition: Carbon steel (ASTM A53 Grade B, API 5L Gr B) or low-alloy steel with optional zinc coating (hot-dip galvanized) or epoxy lining; ≤0.30% carbon for weldability

• Purity/Grade: Commercial grade (CS) and pressure grade (PS); fully deoxidized, no laminations or surface defects

• Physical Characteristics:

  • Form: Seamless or ERW (electric resistance welded) round pipe

  • Outer Diameter: 21.3 mm – 2,540 mm (1/2″ to 100″)

  • Wall Thickness: Schedule 10 through Schedule XXS

  • Length: 6 m, 12 m, or custom up to 18 m

  • Surface: Black, galvanized, or fusion-bonded epoxy (FBE) coated

  • Density: 7.85 g/cm³

• Packaging Options: Bundled with steel straps, plastic end caps, waterproof VCI paper wrap, seaworthy wooden crates or loose bundles for bulk shipping

• Shelf Life: Indefinite when stored indoors or under covered, dry conditions (uncoated steel ≤6 months without rust inhibitor)

3. Core Industrial Applications

• Primary Industries: Municipal water utilities, oil & gas (water injection), mining (slurry and dewatering), power generation (cooling circuits), and heavy construction

• Operational Use Cases:

  • Potable water transmission mains (up to 25 bar pressure)

  • Fire suppression ring mains in refineries and high-rises

  • Raw water intake lines for desalination plants

• Performance Advantages: Outperforms HDPE and PVC in high-temperature (>60°C) and UV-exposed environments; resists creep and deformation under soil loads; allows direct welding for leak-proof joints, unlike threaded plastic alternatives

• Efficiency/Durability: 3x higher tensile strength (≥330 MPa) than ductile iron; maintains flow efficiency (Hazen-Williams C=120 when epoxy-lined) longer due to fewer joint failures

4. Competitive Advantages

• Quality Consistency: ISO 9001:2025 certified; 100% hydrostatic testing (each length) and non-destructive weld inspection (ERW pipes)

• Supply Reliability: Multi-mill sourcing with 40,000 MT monthly capacity; 24/7 dispatch from regional hubs (Rotterdam, Houston, Shanghai, Jebel Ali)

• Logistics Capability: Lead time 14–21 days for standard schedules; emergency 5-day express available

• Price Competitiveness: Direct mill pricing with volume discounts (12–18% below distributor averages for contracts ≥500 MT)

• Sustainability: 98% recyclable content; produced using EAF steelmaking with carbon footprint verified (≤0.45 t CO₂ per ton)

• Technical Support: Full mill test reports (MTRs), welding procedure specifications (WPS), and on-site installation advisory included

5. Commercial & Supply Information

• Minimum Order Quantity (MOQ): BULK 20 MT (mixed diameters allowed within one schedule)

• Loading Capacity: 40‑ft high‑cube container – 25 MT (for OD ≤ 8″ with 6 m lengths); 20‑ft container – 24 MT (for OD ≤ 24″)

• Note: For OD > 24″, break-bulk or flat rack shipping applies; volume discounts trigger at 500 MT/month
