NACE MR0175 Heat Exchanger Tube Bundle

SB111 C70600 Copper Alloy Seamless Tube Bundle for Heat Exchanger NACE MR0175

 

SB111 C70600 Copper Alloy Seamless Tube Bundle

 

C70600 is a 90/10 Copper-Nickel alloy (CuNi 90/10), containing 90% copper and 10% nickel. It is highly resistant to corrosion, especially in seawater and brackish water environments, making it an excellent choice for heat exchanger tubes.

Property Details
Material C70600 (90% Copper, 10% Nickel)
Key Features High corrosion resistance, excellent thermal conductivity, good weldability
Applications Heat exchangers, condensers, marine environments, desalination plants
Standards ASTM B111
Advantages Resistance to stress-corrosion cracking and erosion-corrosion

SB111 C70600 Copper Alloy Seamless Tube Bundle Specific Requirements and Treatment

 

- KILLED CS, NORMALIZED, NACE MR0175/0103, HIC&SSC RESISTANT

Requirement Details Purpose
Killed Carbon Steel Deoxidized steel (e.g., with silicon or aluminum) Reduces voids, improves toughness and ductility
Normalized Heat Treatment Heating above critical temperature and air cooling Refines grain structure, improves mechanical properties
NACE MR0175 Compliance Material resistant to H2S environments Prevents hydrogen-induced cracking (HIC) and sulfide stress cracking (SSC)
HIC Resistance Material resistant to internal cracks caused by hydrogen diffusion Ensures structural integrity in sour environments
SSC Resistance Resistance to cracking under tensile stress and H2S exposure Prevents premature failure in pressure vessels
