There are single-sided seat plates and double-sided seat plates for flange connection seat plates. Structural diagram of flange welded single-sided seat plate (1) Flange welded single-sided seat plate. The flange welded single-sided seat plate is mainly installed on the top, side wall and bottom of the cabin or cabinet as the entrance and exit of the cabin or cabinet. Valves, accessories or pipes can be installed directly on the single-sided seat plate. Flange welded single-sided seat plate is suitable for seawater, fresh water, oil, air and steam pipelines below 300 °C. The commonly used nominal diameter is 15-150 mm, and the nominal pressure is lower than 1.6 MPa. The shape of the single-sided seat plate is similar to the corresponding lap-welded Steel Flange. (2) Flange welded double-sided seat Plate Flange welded double-sided seat plate is generally used for pipelines passing through decks and tanks, and the two sides of the seat plate are respectively connected to valves, accessories or pipes. Flange welded double-sided seat plate, compared with the single-sided seat plate, the double-sided seat plate has an extra shoulder and double-sided installation stud bolts. The outer diameter of the shoulder is 10-20 mm larger than that of the corresponding flange, and the thickness of the shoulder is 6-12 mm. Its scope of application and other structural dimensions are basically the same as those of the single-sided seat plate. The flange welded double-sided seat plate is shown in Figure 3. Its manufacturing and installation method is basically the same as that of the single-sided seat plate, but when marking the position of the screw holes, the positions of the upper and lower screw holes of the seat plate must be staggered from each other and must not overlap; the diameter of the opening on the deck or bulkhead is larger than that of the seat. The plate diameter is 2 to 3 mm larger.
