Large flanges not only save space, reduce weight, but more importantly ensure that joints do not leak and have good sealing performance. The reduction in the size of the compact flange is due to the reduced diameter of the seal, which will reduce the cross-section of the seal face.
Second, the large flange gasket has been replaced by a sealing ring to ensure that the seal faces the sealing surface. In this way, only a small amount of pressure is required to press the cover tightly.
Large flanged threaded connection (wired) flange and welded flange. Low-pressure small-diameter wire-bonded flanges, high-pressure and low-pressure large diameters are all welded flanges. The thickness of the flanges of different pressures and the diameter and number of connecting bolts are different.
As the required pressure is reduced, the size and required number of bolts can be reduced accordingly, so a new product with small size and light weight is finally designed. Large flanges reduce quality and space and play an important role in industrial applications. The flat welding flange connection is to fix two pipes, pipe fittings or equipment on one flange first, and between the two flanges, with flange mats, bolted together to complete the connection.
