Copper Pipe is an important net export product among copper processing materials. Affected by the shrinking international market as well as the U.S. anti-dumping sanctions, its net export volume witnessed a year-on-year decline of 11.0% in 2010, followed by a slight recovery in 2011, but then subjected to Brazil's anti-dumping sanctions in the coming November. Net export volume throughout the year rebounded by a small margin to 146,900 tons, of which, export and import volume were 172,000 tons and 25,100 tons, respectively. Moreover, this report also makes analysis on 13 Chinese copper processing material manufacturers, involving Zhejiang Hailiang Co., Ltd., Zhejiang Honglei Copper Co., Ltd., Anhui Jingcheng Copper Share Co., Ltd., Chinalco Luoyang Copper Co., Ltd., China-Kinwa High Technology Co., Ltd., Jiangxi Copper Corporation, and so on. Being the largest copper pipe exporter and the largest precision copper bar manufacturer in China, Zhejiang Hailiang Co., Ltd. focuses on the machining and trading of precision copper pipes. As of end-2011, the company's copper pipe capacity was 308,000 tons, including 166,000 tons of seamless copper pipes for refrigeration, 120,000 tons of copper and copper alloy pipes for construction / heat exchange, and 22,000 tons of copper alloy pipe fittings. Anhui Jingcheng Copper Share Co., Ltd., China's leading producer of copper plate and strip, is mainly dedicated to the operation of brass series and tin-phosphor bronze series of copper-based alloy plates and strips. In 2011, the company's brass plate and phosphor bronze plate & strip sales reached RMB2930 million and RMB280 million, respectively. In January 2012, its 30,000 t/a High Precision Copper Plate and Strip Project officially went into operation. Following the advancement of this project, the company's product line will be further extended.
