High-Quality C122 Seamless Copper Tubing from China Suppliers | ASTM B280 Factory Products
Copper Pipe
High strength at low temperatures. Commonly used in the manufacture of heat exchange equipment (such as condensers), and in the assembly of low-temperature pipelines in oxygen production equipment. Small-diameter copper pipes are often used to transport pressurized liquids (such as lubrication systems, hydraulic systems, etc.) and as pressure measuring pipes for instruments. Copper pipes are robust and corrosion-resistant, making them the first choice for modern contractors in the installation of water supply, heating, and cooling pipes in all residential and commercial buildings.

💰
EconomicalCopper pipes save on materials and overall installation costs, offering stability and reliability while eliminating the need for maintenance.
-
⚖️
LightweightCopper pipes are thinner than ferrous metals for the same inner diameter, reducing transportation costs and saving space during installation.
-
🔧
Flexible & DeformableCopper pipes can be bent and deformed into elbows and joints, with smooth bends allowing any angle.
-
🔗
Easy to ConnectCopper pipes are simple to connect, reducing labor time and installation complexity significantly.
-
🛡️
Safe & ReliableLeak-proof, non-combustible, produces no toxic gases, and is corrosion-resistant across various environments.
-
🌡️
High Temperature ResistanceCopper has a melting point of 1083°C, making hot water system temperatures negligible for copper pipes.
⚠️ Did You Know? Archaeologists have discovered copper water pipes dating back 4,500 years inside the Egyptian pyramids — and they are still usable today. In contrast, galvanized steel pipes are prone to rust, causing yellowing tap water and reduced flow after short use.

Frequently Asked Questions (FAQ)
What are the main applications of copper pipes?
Copper pipes are widely used in heat exchange equipment (such as condensers), low-temperature pipelines in oxygen production equipment, water supply systems, heating and cooling systems, lubrication systems, hydraulic systems, and instrument pressure measuring pipes in both residential and commercial buildings.
What sizes and specifications are available for your copper pipes?
Our copper pipes are available with an outer diameter (OD) ranging from 2mm to 914mm and a wall thickness (WT) from 0.5mm to 80mm. Standard lengths include 1m, 2m, 3m, 4m, 5.8m, and 6m, with custom lengths available upon request.
What international standards do your copper pipes conform to?
Our copper pipes conform to multiple international standards including ASTM, JIS, DIN, GB, and EN, ensuring compatibility with global project requirements and quality assurance.
Why are copper pipes preferred over galvanized steel pipes?
Copper pipes are highly corrosion-resistant and do not rust over time, unlike galvanized steel pipes which are prone to rust — causing yellowing tap water and reduced water flow. Copper also withstands high temperatures (melting point: 1083°C), making it far safer and more durable for hot water applications.
What processing services do you offer for copper pipes?
We offer a full range of processing services including bending, decoiling, welding, punching, and cutting, allowing us to meet customized project specifications and requirements.
What are the available trade and shipping terms?
We support multiple international trade terms including Ex-Works (EXW), CIF, FOB, CFR, and CNF. We export to countries including Korea, India, the UK, Singapore, Dubai, and many more regions worldwide.
