Liam Pipes and Tubes is a major manufacturer and supplier located in Houston, USA, with a reputation for supplying quality pipes and tubes to a variety of industries. Liam puts great emphasis on quality, and sells a huge variety of products, such as Copper Nickel ERW (Electric Resistance Welded) pipes, which offer an excellent combination of corrosion resistance, strength, & durability. They are used in marine, chemical, and offshore environments where corrosion is a concern. We will get them delivered on time & take great pride in service!
Copper Nickel ERW Pipes are made of 90% copper and 10% nickel, with slight amounts of iron and manganese. This gives them very good corrosion resistance to seawater and other marine environments, which is partly responsible for their durability. Mechanically, they have good tensile strength in the range of 240 – 400 MPa, with decent yield strength of about 180 – 275 MPa, and very good flexibility. They also have very good thermal conductivity and very good resistance to pitting, crevice corrosion and good resistance to bio-fouling. All of these properties mean that they are useful in marine, desalination and chemical industries.

Copper Nickel ERW (Electric Resistance Welded) pipes are often used in various marine, chemical processing, and desalination applications because of their excellent corrosion resistant properties in seawater service. They are well-suited for applications subject to extreme conditions where corrosion protection is paramount, such as shipbuilding, offshore platforms, and heat exchangers. They are known to have high strength, can resist biofouling, and are extremely durable in salty or chemically aggressive environments. Copper-nickel ERW pipes are likely used in power plants, water treatment facilities, and in HVAC systems, for their excellent thermal conduction properties and oxidation resistance.
