Forged Pure Copper Heavy Tube – Process & Quality Assurance Statement
Our forged pure copper heavy tubes are produced through intensive hot forging to deliver exceptional wall thickness, density, and mechanical performance, making them suitable for applications where standard extruded or drawn tubes cannot withstand the required pressures or thermal loads.

Key process features

The forging process transforms the material to achieve superior integrity in thick-walled configurations:
●Billet Selection: Premium high-purity copper ingots are verified for composition and cast into solid billets.
●Preheating: Billets are heated uniformly to forging temperature to ensure complete plasticity without grain growth.
●Hot Forging: Multiple heavy-duty press or hammer operations form the thick-walled tube, closing internal voids and aligning grain flow for maximum strength.
●Piercing & Sizing: Mandrel piercing establishes the inner diameter, followed by sizing passes for precision.
●Controlled Cooling: Gradual cooling minimizes residual stresses and preserves conductivity.
●Annealing: Full stress-relief heat treatment restores optimal electrical properties and ductility.
●Finishing & Protection: Tubes are straightened, ends beveled, and surfaces lightly coated to prevent oxidation during handling and shipping.

Quality control system

● Complete traceability from raw ingot batch to finished heavy tube
● Comprehensive test reports including conductivity and pressure test data provided with each shipment
● Sample retention ≥3 years for third-party validation (SGS, BV, TÜV, etc.)
● 100% inspection of critical parameters:
• Chemical purity and oxygen content (spectrometric analysis)
• Mechanical properties (tensile, burst pressure, and hardness testing on samples)
• Dimensional accuracy (ultrasonic wall thickness + CMM; typical tolerance ±1% on OD/wall)
• Surface and internal quality (visual + eddy current/ultrasonic examination)
• Conductivity measurement (typically >100% IACS)
● Internal standards exceed ASTM B280 requirements. Typical C11000 forged heavy tube properties: Enhanced tensile strength ≥350 MPa, Superior pressure rating, Dense wall structure free of internal defects.
● ISO 9001:2015 certified production ensures every forged pure copper heavy tube provides the strength, conductivity, and reliability demanded by your most rigorous applications.
