Abstract: Following the continuously going up of the crude oil prices in the world market, exploration of lo-cal crude oil sources has been enhanced in U.S.A., resulting in change of the demand for OCTG.Fluctuating along with the price of crude oil, the price of OCTG in U.S.A.had kept going up during the period of 2004-2006.Based on analysis with the principle of statistics, the trend of the OCTG pricing over the recent years in the country is identified, i.e., the price is rather high in the second and the third quarters of the year, while it goes down to the valley in the fourth quarter.Owing to the increasingly expanding of OCTG export from China to U.S.A. with comparatively low prices, it is possible for U.S.A.to launch an anti-dump proceedings against China, and this very development should be closely followed by relevant industrial circles in China.
