Seamless Copper Tube

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.

Kobberrør er nemme at installere, Billig at transportere og har lang levetid med lav vedligeholdelse. Fordi de er kompatible med en lang række væsker og er så modstandsdygtige over for en lang række miljøforhold, rør lavet af kobber giver en langsigtet ydeevne, der er ekstremt omkostningseffektiv over lange perioder. De danner rørsystemer både over og under jorden, i frysende temperaturer såvel som i applikationer med høj varme. Brandsprinkleranlæg, Kryogene planter, klimaanlæg og køleanlæg, Iltsystemer på hospitaler, Gas- og dampvarmesystemer og afløbs-/udluftningssystemer bruger alle kobberrør som rør. De tager også mindre plads end andre metalrør.

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.
