C12200 Phosphorus Deoxidized Copper Seamless Tube for Heat Exchanger & Refrigeration System

1. General Introduction

UNS C12200 is a high-purity phosphorus deoxidized copper (Cu-DHP), the most widely used seamless copper tube for refrigeration, HVAC, heat exchangers and fluid transmission systems. Different from ordinary pure copper, C12200 adds trace phosphorus for deoxidation, which completely eliminates hydrogen embrittlement risk (hydrogen disease) and greatly improves welding, bending and flaring performance.

All our C12200 copper tubes are produced by cold-drawn seamless technology, featuring smooth surface, precise dimensional tolerance and stable mechanical properties. The seamless structure avoids leakage risks, making it ideal for long-term operation in refrigeration, plumbing and industrial heat exchange equipment.

2. Material Performance Explanation

C12200 phosphorus deoxidized copper maintains the excellent thermal conductivity and electrical conductivity of pure copper. Its outstanding corrosion resistance ensures stable service in fresh water, refrigerant and dry gas environments, and will not easily form oxide scale to block pipelines. This material can be processed in reducing atmosphere, suitable for various cold and hot forming processes. It is the standard preferred material for air conditioning condensers, evaporators, building water pipes and petrochemical fluid pipelines worldwide.

FAQ

What is C12200 copper?
C12200 is UNS standard phosphorus deoxidized copper (Cu-DHP), equivalent to Chinese standard TP2. It is a high-purity copper material with low oxygen content, mainly used to produce seamless copper tubes for refrigeration and plumbing systems.
What is the difference between C12200 and C11000 copper?
C12200 contains trace phosphorus for deoxidation, no hydrogen disease, better welding and bending performance; C11000 is pure copper with higher conductivity but poor high-temperature processing performance.
Is C12200 copper tube suitable for refrigeration systems?
Yes. C12200 is the mainstream material for air conditioning and refrigeration tubes, with efficient heat conduction and reliable anti-leakage performance.
Can you provide customized sizes for C12200 copper tubes?
Yes. We support customized outer diameter, wall thickness, length, surface treatment and testing standards according to customer drawings and requirements.
What certifications do your C12200 copper tubes have?
Our products are certified by ISO, RoHS, SGS, TUV, and provide EN10204 3.1 mill test reports. Third-party inspection is supported.
