What is a C11000 copper pipe?
Our Copper Alloy C11000 Pipes are also resistant to non-oxidizing minerals such as hydrochloric and sulfuric acids; organic acids such as acetic acid, citric, and fatty acids; and acidic solutions containing sulfur, such as sulfurous acid and sulfite solutions. These Copper C11000 Pipes are considered to be resistant to stress corrosion cracking in ammonia and other similar environments that produce season cracking in brass and other copper alloys.
Copper C11000 Pipes are utilized in a variety of sectors, including pulp & paper, energy production, maritime and naval, automobile, petroleum and gas, aeronautical, and agricultural applications.
All of our Copper C11000 Pipes are tested under multiple quality standards, from raw material procurement to product packaging, to guarantee they are defect-free and appropriate for usage in a variety of climatic circumstances.
