Seamless Copper Tube
Advantages of Copper Tube. The primary reasons for this are: Copper is economical. The combination of easy handling, forming and joining permits savings in installation time, material and overall costs. Long-term performance and reliability mean fewer callbacks, and that makes copper the ideal, cost-effective tubing material.

Phosphorus-Deoxidized copper tubes – C12200 – are extensively used in sugar refineries for condensers and evaporators. Deoxidized copper is the standard material for transferring heat from steam to water or air because of their excellent resistance to corrosion by fresh water and their high thermal conductivities.
Copper tubes are easy to install, inexpensive to transport and have long life spans with low maintenance. Because they are compatible with a large range of liquids and are so resistant to a wide variety of environmental conditions, tubes made of copper provide a long term performance that is extremely cost effective over long periods of time. They form piping systems both above and below ground, in freezing temperatures as well as in high heat applications. Fire sprinkler systems, cryogenic plants, air conditioning and refrigeration systems, hospital oxygen systems, gas and steam heating systems and drain/vent systems all use copper tubes as pipes. They also take up less space than other metal pipes.
In order to ensure safety and quality, all copper tubes must adhere to strict ASTM (American Society for Testing and Materials) standards concerning copper purity, design, fittings and liquid/gas compatibility. They are generally formed by the extrusion process, which fabricates seamless tubes with uniform wall thickness and a smooth surface. Solid-profile copper billets in the shape of rods are heated until malleable and then forced through a series of smaller and smaller molds in the shape of a tube until the desired shape has been reached. After extrusion, they are often bent using rollers or mandrels, and attached to each other at the ends by welding.
Most copper tubes have threaded ends, one male and one female, so they can easily attach and detach from one another. The threading is non-permanent but still provides a reliable, air and water tight seal. Sometimes tubes are joined by brazing, a welding technique that uses nonferrous filler material. A benefit of copper tubes is their flammability and explosion resistance. If a fire does start within the tube, it will not travel farther into the pipe system. Copper tubes can have either soft or hard tempers, which is the metal’s overall hardness. This is accomplished by post-fabrication heat treatments.

A vehicle’s braking system is as crucial to a vehicle’s performance as its engine and drive train. The tubing carrying pressurized air or fluid through the system is the vital link between master cylinder and slave cylinders at the wheels.
Brake system tubing is vulnerable to the pressures of air or fluid flowing through it, to corrosion from road mud and salt, and to damage of any protective coatings on its surfaces from stone pecking where it is exposed under the chassis.
Copper-nickel alloy C70600, an alloy of 90% النحاس و 10% nickel, is inherently corrosion resistant to road salt, and its use as brake tubing is increasing based on: 1) Changing life-expectancy for automotive vehicles; 2) Worldwide service-experience data on brake tubing wear; و 3) Increasing cost of corrosion-retarding coatings for steel brake tubing.
