    Tubes sans soudure étirés à froid

    Cold Drawn Seamless as implied is made by cold drawing a larger mother seamless pipe, which is generally manufactured through a HFS process. In the Cold Drawn Seamless process, the mother pipe is pulled through a die & plug in cold without any heating. Because of the tool on outside and inside the surface and tolerances are better in Cold Drawn Seamless. While this is an additional process over HFS, it is necessary to get smaller size pipes which otherwise cannot be manufactured in HFS. S...
