C12200 Copper Pipe

Factory Direct High-Purity C12200 Copper Pipe & Tubing for HVAC Refrigeration, Plumbing & Industrial Systems

C12200 copper pipe (UNS C12200 copper tube, DHP high-phosphorus deoxidized copper pipe, Cu-DHP seamless refrigeration tube, CW024A industrial tubing, and AC pancake coil copper pipe) is produced using continuous extrusion, cold drawing, and bright hydrogen annealing processes to deliver superior thermal conductivity, excellent cold bending performance, high pressure resistance, and 100% immunity to hydrogen embrittlement. Engineered for HVAC air conditioning refrigeration (ACR) systems, potable water plumbing, medical gas distribution lines, heat exchangers, and hydraulic oil lines, C12200 copper pipe provides smooth internal surfaces, tight wall thickness tolerances, and exceptional joint integrity during high-temperature brazing.

At XQJ Metal, we operate advanced cold drawing benches, eddy current non-destructive testing units, hydraulic pressure test rigs, and protective atmosphere annealing furnaces to manufacture premium C12200 copper pipe products conforming strictly to international standards, including ASTM B280 (air conditioning and refrigeration field service tube), ASTM B88 (seamless copper water tube), ASTM B75, EN 12735-1 (Cu-DHP / CW024A), JIS H3300 (C1220), and GB/T 1527 (TP2) specifications. We supply outer diameters (OD) from 3mm to 219mm (0.118 inch to 8.62 inches), wall thicknesses from 0.5mm to 10mm (0.020 inch to 0.394 inch), straight lengths up to 6 meters, continuous 15m/30m/50m pancake coils, and custom tempers from dead soft annealed to hard drawn.

Metallurgical Advantages of UNS C12200 (Cu-DHP) Seamless Copper Tube over ETP Copper

Selecting high-purity phosphorus deoxidized copper tubing is crucial for pressure containment, brazing integrity, and long-term corrosion resistance in heating and cooling systems. C12200 copper pipe provides distinct metallurgical benefits over conventional ETP copper (C11000):

• Complete Immunity to Hydrogen Embrittlement: Standard ETP copper (C11000) contains cuprous oxide ($Cu_2O$) that reacts with hydrogen during high-temperature flame brazing to form water vapor bubbles, causing internal micro-cracks. C12200 is treated with 0.015%–0.040% residual phosphorus, completely removing free oxygen and making the tube 100% immune to hydrogen embrittlement during torch brazing and furnace welding.
• Superior Bending, Flaring & Swaging Ductility: Soft annealed C12200 copper tubing exhibits exceptional elongation (≥ 40%), allowing tight 180-degree cold bends and flare connections without wall necking, surface flaking, or circumferential cracking.
• High Cleanliness & Internal Surface Smoothness: Processed with nitrogen purge bright annealing, C12200 ACR tubes maintain ultra-clean inner walls with carbon residue far below ASTM B280 limits (< 0.038 g/m²), preventing compressor motor insulation failure and valve clogging.

• Precision Straight Length Cutting: Custom cut lengths from 100mm to 6000mm with burr-free end facing, chamfering, and deburring ready for immediate socket welding or press-fitting.
• Custom End Forming & Bending: Pre-bent U-bends, expanded socket ends, flared ends, and reduced manifold headers customized to customer OEM drawings.

Primary HVAC, Plumbing, Medical & Industrial Applications

Our seamless C12200 copper pipe products are widely deployed across critical fluid delivery and thermal control systems worldwide:

• Air Conditioning & Refrigeration (ACR): R410A / R32 / R134a refrigerant lines, split system interconnecting tubing, chiller plant coils, and VRF/VRV branch pipe networks.
• Plumbing & Potable Water Networks: Hot and cold water distribution pipes, underground service lines, heating risers, and fire sprinkler systems.
• Medical Gas & Vacuum Systems: Cleanroom medical oxygen, nitrous oxide, compressed air, and vacuum suction piping in hospitals.
• Industrial Heat Transfer & Energy: Shell-and-tube heat exchanger bundles, solar water heater absorber tubes, oil cooling loops, and condenser coils.

Quality Control, Pressure Audits & Seaworthy Export Packaging

To ensure zero-leak reliability, uniform wall thickness, and pristine surface cleanliness, XQJ Metal enforces rigorous Quality Assurance (QA) protocols for every C12200 copper pipe shipment:

• 100% Non-Destructive & Hydrostatic Testing: Every tube undergoes online eddy current testing (ECT) per ASTM E243 and high-pressure hydrostatic/pneumatic leak testing to verify pressure integrity.
• Chemical & Cleanliness Verification: Spectrometric alloy analysis (Cu ≥ 99.90%, P 0.015%–0.040%), tensile testing, grain size measurement, and solvent wash inner-wall residue tests certified with Mill Test Certificates (MTC EN 10204 3.1).
• Moisture-Proof Export Packaging: Pipe ends are sealed with plastic dust caps, wrapped in moisture-resistant VCI film, bundled in protective woven sleeves, and loaded into sturdy ISPM-15 wooden boxes or heavy-duty cardboard tubes for ocean freight.

Frequently Asked Questions (FAQ)

Q1: What is the main difference between C12200 copper pipe and C11000 copper pipe?

A: C12200 is phosphorus deoxidized (Cu-DHP), making it completely immune to hydrogen embrittlement during torch brazing and welding. C11000 contains residual oxygen and is susceptible to cracking when brazed at high temperatures, making C12200 the standard choice for HVAC and plumbing pipes.

Q2: Can XQJ Metal supply C12200 copper pipe in pre-dehydrated pancake coils with nitrogen caps?

A: Yes, we provide soft annealed C12200 ACR copper pancake coils (1/4″ to 7/8″ OD) thoroughly cleaned, dehydrated, purged with nitrogen gas, and sealed with plastic end plugs according to ASTM B280 standards.
