A flange, the widespread use and promotion in the machinery industry, users get the praise and favor. Extensive use of welded flange, determined by using a range of different characteristics, used under medium conditions are relatively mild conditions, such as low-voltage non-purify compressed air, low-pressure water circulation Looper flange, it has the advantage of cheaper prices.
