China's Ministry of Commerce announced Saturday that it will continue to impose anti-dumping duties on imports of alloy-steel seamless pipes from the United States and the European Union.
The latest measures will take effect on Sunday and will last five years, the ministry said in a statement. 
High temperature and high pressure alloy steel and seamless steel tubes are mainly used in supercritical and ultra-supercritical boilers and steaming-water pipes in power stations.
