Thick steel coil / thick seamless tube / pipe manufacturers Liaocheng coils 
 The production of thick-walled steel pipe coil in Wuxi has been generally, but the production of special thick-walled pipe or no new breakthrough, latest technology in Wuxi Special Steel Amtran thick hot rolled steel coils. 
 Roll with hot roll process a variety of thick-walled steel pipe, special thick-walled steel coil, steel coil uses a large area in Jiangsu Province, heavy industry continues to develop, thick-walled steel pipe sales continue to increase, in November 2011 sales coil steel 6,000 tons, the production volume size specification sheet steel 1.2 million tons, 35.6% than planned. 
 Coil steel production technology to improve not only represents the board of Wuxi Special Steel Amtran volume improvements in technology, also proved true in Wuxi Amtran steel production capability in the production plan in 2012 will be the new high.
