A very good solution for the creation of stainless steel pipes and manifold involves the use of free sliding flanges in order to avoid the orientation of the bolt holes that happens for flanges welded by means of overlap weld.
The positioning of the valves or components all along the pipe can be oriented by means of the rotation of free flanges until joining them. In particular, pressed flanges – by virtue of their peculiar shape – allow the lightening of the joint. This results in a variety of advantages both in terms of lifting the pipe and in terms of price (due to the lower weight of the flanges).http://www.wuxiyizhuo.com/stainl
