As a manufacture of drill pipe in China, we have produced many 5'' drill pipe in 2008 and at that time this product is popular in the market, but now it is not so popular, as a merchaindiser, I feel a great pressure, anyone can give me some advice to how to deal with? if you have a good suggestion, kindly please send me an e-mail(francisco@rontech.com.cn)

Thank you so much for your attention
