quality PL Flange not only saves space and weight, but more importantly, it ensures that the joints will not leak and has good sealing performance. The reduced size of the compact flange is due to the reduced diameter of the seal, which reduces the cross-section of the sealing face. Second, the quality PL Flange gasket has been replaced by a sealing ring to ensure a match of the sealing face to the sealing face. In this way, only a small amount of pressure is required to compress the sealing surfaces.

　　As the required pressure is reduced, the size and number of bolts required can be reduced accordingly, so the result is a new product design that is small and lightweight. Therefore, the quality PL Flange on sales type is a relatively high-quality flange product, which reduces the quality and space, and plays an important role in industrial applications.

　　The sealing principle of quality PL Flange on sales: The two sealing surfaces of the bolt press the flange gasket against each other and form a seal, but this also leads to the destruction of the seal. In order to keep the seal, it is necessary to maintain a huge bolt force, for this reason, the bolt will be made bigger. And larger bolts will match larger nuts, which means that bolts with larger diameters are required to create conditions for tightening the nuts.

　　Fundamentally, the quality PL Flange on sales is an ineffective seal that requires 50% of the bolt load to squeeze the gasket and only 50% to maintain pressure.
