Product Description
The Thick Wall Corrosion Resistant Copper Pipe for Plumbing is a high-performance piping solution engineered to deliver longevity and reliability in potable water systems, heating networks, and industrial applications. Constructed from C12200 phosphorus-deoxidized copper (DHP copper), these pipes combine superior corrosion resistance with structural integrity, making them ideal for environments requiring durability and hygienic performance.
Parameter | Value |
Alloy Type | C12200 (DHP copper) |
Outer Diameter | 15–200mm |
Wall Thickness | 1.2–4.0mm (Type K/L per ASTM B88) |
Tensile Strength | ≥205MPa |
Corrosion Resistance | Passes ASTM B88 salt spray test |
Surface Finish | Bright annealed, lead-free |
ASTM B88 Compliance: Manufactured to ASTM B88 standards, these pipes ensure dimensional accuracy and leak-free performance in pressure systems up to 1.6MPa .
Superior Corrosion Resistance: C12200 copper resists oxidation, chloride-induced pitting, and chemical degradation, with a lifespan exceeding 50 years in potable water applications .
Seamless Construction: Eliminates weak points from welding, ensuring burst pressure resistance of 10–15MPa for high-demand systems like fire sprinklers .
Hygienic Performance: Copper’s antimicrobial properties reduce biofilm formation by 99.9%, meeting NSF/ANSI 61 standards for drinking water .
Residential & Commercial Plumbing: Hot and cold water distribution systems benefit from the pipe’s low friction coefficient (≤0.012) and resistance to scale buildup .
Industrial Processes: Chemical plants and food processing facilities use these pipes for transporting alkaline solutions and sterile liquids due to their non-reactive surface .
Heating & Cooling Systems: High thermal conductivity (385 W/m·K) ensures efficient heat transfer in radiant floor heating and chiller systems .
Medical Gas Systems: Compliant with ASME B31.1 standards, these pipes are used for oxygen and nitrogen delivery in hospitals .
Q: Can these pipes be used in saltwater environments?
A: While C12200 copper resists mild saline conditions, marine applications require naval brass (C44300) or cupronickel alloys for enhanced resistance to chloride corrosion .
Q: What joining methods are recommended?
A: Use ASTM B32 lead-free solder or ASME B16.18 compression fittings for secure connections. Avoid brazing in potable water systems to prevent flux contamination .
