Foreword

This standard is drafted in accordance with the rules given in GB/T 1.1-2009. This standard is equivalent to the international standard ISO 2563..2009 "aircraft pipe and pipe V-type clamp connection flange contour size." This standard is proposed by China Aviation Industry Corporation. This standard is under the jurisdiction of the National Aviation Standardization Technical Committee (SAC/TC435). The drafting of this standard. China Aviation Comprehensive Technology Research Institute, China Commercial Aircraft Co., Ltd. Shanghai Aircraft Design and Research Institute. The main drafters of this standard. Li Junsheng, Wen Fang, Jin Xin. Aircraft piping and piping Type of V-Clamp Connection Flange

1 Scope

This standard specifies the dimensions of the flange for connecting the British-made pipe and the pipe V-type clamps, including. --- light solid flange contour; --- medium solid flange contour; --- Heavy-duty solid flange profile; - Narrow sheet metal flange profile; --- wide sheet metal flange profile; --- wide solid flange outline; --- wide sheet metal with solid flange outline.

2 size

2.1 According to the specific use of the type, V-shaped clamp flange in the combination of the outline of the size should be consistent with the provisions of Figure 1 to Figure 7. The dimensions are given in millimeters and the corresponding inch values are given in parentheses. 2.2 The pre-installed design is optional by the user, but the pre-installed design should be within the contour profile given in this standard. 2.3 Schematic diagram of the symmetrical flange is given, but depending on the user's choice, the flange surface may be asymmetric, allowing a combination of contours Within the use of complementary tenon structure or other complementary surface. The width of the sheet metal flange is symmetrical. The single wide sheet metal flange shown in Figure 7 is suitable Figure 6 shows a single solid flange fit. 2.4 The single solid flange shown in Figure 7 can be machined on a pump or valve with the pipe. Unit in millimeters (inches) Description. 1 - Outside diameter of pipe. a gauge size. b Nominal size. Figure 1 Light solid solid flange profile ...
