光滑面法兰一般只用于低压，配软质的薄密封垫；
Smooth surface only commonly used for low pressure, flange with soft qualitative thin gasket;
如果要用金属垫片，则应将光滑面缩小，使其与垫片的接触面积减小。
If want to use metal gasket, it should be smooth surface narrowed, make its and gaskets of contact area is reduced.
如果要用金属垫片，则应将光滑面缩小，使其与垫片的接触面积减小。
If you use metal gaskets, smooth surface should be reduced, to reduce the contact area with the pads.
这样，在螺栓张力相同的情况下，缩小后的窄光滑面的压紧应力就会增大。
Thus, under the same bolt tension, reduce narrow smooth surface after the compressive stress will increase.
取下UVSCALE，观察颜色分布，确定光量分布。 * 观察时使用非光滑面。
