The F.F.X forming method for ERW line is one kind of advanced mature forming system which we design and manufacture ourselves for 10 years. We developed this system according to our many years experience and by means of foreign correlation technique. The rate of save the use of rollers and product quality is nearly the same to latest technical mode. This roll pass technical has the characteristic of forming steadily, high quality and convenient change specification, especially suitable for large thickness and high quality. And this technical can improve the quality of products greatly in plate shape, roundness, surface quality of the pipe, flattening test and so on.
