LF2 flange

LF2 flange LF2 belongs to American standard low temperature alloy steel forgings. Executive standard: ASME SA350/SA350M-2004

Sealing principle of LF2 flange. However, the larger the bolt diameter is, the better. Because the larger the bolt diameter is, the suitable flange will bend, which can only increase the wall thickness of the flange part. The whole equipment needs a large size and weight, which has become a special problem in the environment. In this case, weight has always been a major concern. In addition, LF2 flange is a kind of failure seal, which requires 50% of the bolt load to squeeze the gasket, 50% load can maintain the pressure

LF2 flange not only saves space and weight, but also protects the joint from water leakage and has good sealing performance. The size of the compact flange is reduced by reducing the seal diameter, thereby reducing the section of the sealing surface

Replace the flange gasket with a sealing ring to confirm that the sealing surface matches the sealing surface. In this way, the sealing surface can be compressed with only a small amount of pressure. With the reduction of the required pressure, the size and number of bolts will decrease accordingly. Therefore, a new product with small volume and light weight (70% - 80% less than the traditional flange) has been designed

Application of LF2 flange

LF2 flange has the advantages of convenient installation and low cost, so it is widely used. LF2 flange is suitable for pipeline systems with low pressure rating, small pressure fluctuation and small vibration. LF2 flange is a relatively good flange product, which reduces the mass and space of flange and plays an important role in industrial application
