Description
Thick-wall corrosion-resistant copper pipe for plumbing systems serves as a piping solution engineered for potable water systems, heating networks, and industrial applications. Constructed from C12200 phosphorus-deoxidized copper (DHP copper), these pipes combine corrosion resistance with structural integrity. The material composition supports durability and hygienic performance in environments where these properties are required.
Manufactured to multiple international standards including GB/T 2529-2012, ASTM187M, JIS, and ROHS, these pipes are available in outer diameters ranging from 6-350mm. The standard production range focuses on 15-200mm outer diameter with wall thicknesses of 1.2-4.0mm, corresponding to Type K and Type L specifications per ASTM B88. The minimum order quantity is 200 kilograms for commercial procurement.

Manufactured to ASTM B88 standards, these pipes maintain dimensional accuracy and support leak-free performance in pressure systems operating up to 1.6MPa. The standardization ensures compatibility with industry-standard fittings and installation methods.
C12200 copper demonstrates resistance to oxidation, chloride-induced pitting, and chemical degradation. In potable water applications, the material exhibits a service life exceeding 50 years under normal operating conditions.
The seamless manufacturing process eliminates potential weak points associated with welded joints. This construction contributes to the burst pressure resistance of 10-15MPa, making the pipes suitable for high-demand systems such as fire sprinklers.
Copper's inherent antimicrobial properties reduce biofilm formation by 99.9%. The pipes meet NSF/ANSI 61 standards for drinking water applications, supporting safe water distribution in residential and commercial buildings.
Hot and cold water distribution systems benefit from the pipe's low friction coefficient (≤0.012) and resistance to scale buildup. These properties contribute to consistent water flow and reduced energy consumption for pumping.
Chemical plants and food processing facilities utilize these pipes for transporting alkaline solutions and sterile liquids. The non-reactive surface prevents contamination of process fluids and maintains product purity.
With a thermal conductivity of 385 W/m·K, these pipes facilitate efficient heat transfer in radiant floor heating and chiller systems. The material's temperature stability supports operation across a wide range of thermal conditions.
Compliant with ASME B31.1 standards, these pipes are used for oxygen and nitrogen delivery in healthcare facilities. The smooth interior surface minimizes particle entrapment and supports clean gas distribution.
While C12200 copper resists mild saline conditions, marine applications require naval brass (C44300) or cupronickel alloys for enhanced resistance to chloride corrosion.
Use ASTM B32 lead-free solder or ASME B16.18 compression fittings for secure connections. Brazing is not recommended in potable water systems to prevent potential flux contamination.
The minimum order quantity for thick-wall corrosion-resistant copper pipe is 200 kilograms. Custom sizes and specifications are available for larger volume orders.
