The Nov. price of the fluid pipes

　　We are a factory of fluid pipes. Such as ASTM 106 Grb seamless fluid pipes, API5L Grb fluid pipes etc. I had quoted to our clients for seamless fluid pipes. Because it is a tender so need long time to make the decision. But our seamless fluid pipes since Sep. to now each ton had increased 400 RMB per ton. It will be a big gap between the current price and the quoted prices. So I have to contact our clients to give the news of increasing rate.  It is our duty and this is our service. And the customer have the right to know the prices timely.
