45° Pure Copper Socket Elbow – Process & Quality Assurance Statement

Our 45° pure copper socket elbows are precision-manufactured to provide reliable, leak-free connections in high-performance piping systems where thermal efficiency and corrosion resistance are critical.

Key process features

The complete production process ensures consistent quality and perfect fit:
●Material Selection: Only certified high-purity copper tubes meeting ASTM B88 are used, with full mill certificates for traceability.
●Forming: Tubes are cut to precise lengths and formed using advanced hydraulic pressing or spinning technology to create the exact 45° angle and socket depth.
●Machining: The socket end and sealing surfaces are precision-machined to tight tolerances for optimal capillary soldering.
●Deburring & Cleaning: All internal and external burrs are removed, followed by thorough ultrasonic and chemical cleaning to eliminate contaminants.
●Annealing (if required): Controlled atmosphere annealing restores ductility while maintaining mechanical strength.
●Final Inspection: Every elbow undergoes 100% visual, dimensional, and pressure testing before packaging.
●Packaging: Elbows are individually wrapped in protective film and packed in sturdy cartons or pallets to prevent damage during global shipping.

Quality control system

● Full traceability from raw copper tube lot to finished elbow
● Material certificates and inspection reports provided with every shipment
● Sample retention ≥3 years for third-party verification (SGS, BV, TÜV, etc.)
● 100% inspection of critical parameters:
• Chemical composition and purity (spectrometric analysis)
• Dimensional accuracy (CMM and go/no-go gauges; socket depth and angle tolerance ±0.2mm / ±1°)
• Surface cleanliness and finish (visual and magnified inspection)
• Pressure tightness (air or hydrostatic test up to 3.0 MPa)
• Socket roundness and wall thickness uniformity
● Internal standards strictly exceed ASME B16.22 and ASTM B88 requirements. Typical C11000 properties:
Excellent solder joint strength, Thermal conductivity >390 W/m·K, Proven pressure rating up to 1000 PSI depending on size.
● ISO 9001:2015 certified facility ensures every 45° pure copper socket elbow meets the highest standards of quality, reliability, and performance for your critical piping systems.
