It is an intergovernmental commodity organization dedicated to solving problems affecting copper production, use, and trade, paying particular attention to issues such as market transparency, market access, and sustainable development.

Frequency welded pipe characterized by: welding speed large and  welding heat affected zone small, weld the workpiece may not clean up, can weld  thin-walled tube, can weld metal pipe.Production process depends mainly on the variety of materials, from raw materials to finished products need to go through a series of processes, these processes need kinds of machinery and welding equipment, electrical control, testing equipment, such equipment and fittings in accordance with a different process requires more reasonable arrangement, high frequency welded typical process: Slitting - unwinding - strip leveler - head and tail cut - steel welding - looper accumulator - forming - welding - deburring - sizing - testing - fly cut - initial inspection - straightening steel - pipe processing - hydrostatic test - flaw detection - printing and coating - finished.
