Flange welding
April 09, 2019
The main design flaw of flat-welded flanges is that it does not guarantee zero leakage. This is its design deficiencies: the connection is dynamic, and periodic loads such as thermal expansion and undulation, can cause movement between the flange faces, affecting the function of the flange, thereby compromising the integrity of the flange and eventually leading to leakage. Any product can not be without defects, but try to control the product to the minimum, so the company in the production of flat welding flange try to improve product performance, to make the most of its role. Flat welding flange features: Flat welding flange not only saves space, reduce the weight, more importantly, to ensure that the joints will not leak, with good sealing performance. The reason why the compact flange size is reduced is due to the reduced diameter of the seal which will reduce the cross-section of the sealing surface. Second, the flange gasket has been replaced by a seal ring to ensure that the sealing surface is matched to the sealing surface. As a result, only a small amount of pressure is required to compress the sealing surface. As the required pressure is reduced, the size and number of bolts required can be reduced accordingly, resulting in a small, lightweight new design (70-80% lighter than traditional flanges) product. Therefore, a flat flange welding quality flange products, reducing the quality and space, played an important role for industrial purposes. More Search Keywords: Flanges
