The spiral pipe mill was first built by HUAYE in 2004 and stopped production in 2011; HUAYE has done fully refurbish and major upgrade to the machine in July 2014. Now it is installed in line in HUAYE's warehouse for sale. It also has beveling machine and hydrostatic tester available together with the machine. (Watch a video)
