Steel Line Blanks

SECTION I-GENERAL

1 . I Scope This standard provides dimensions for operating line blanks

(or “blinds”) in sizes NPS 95 through NPS 24 for installation between ANSI B16.5 flanges in the 150,300,600,900, 1500, and 2500 pound pressure classes. The dimensions are suitable for blanks made of ten different steel plate materials. Line blanks used only for pressure testing are not part of this standard.

1.2 Definitions 1.2.1 A Figure 8 blank (also called a spectacle blank) is a pressure retaining plate with one solid end and one open end connected with a web or tie bar (see Figure 1).

1.2.2 Apaddle blank is similar to the solid end of a figure 8 blank (with a handle) and is generally used in conjunction with a paddle spacer in large sizes (see Figure 1).

1.2.3 Apaddle spacer is similar to the open end of a figure 8 blank (with a handle) and is generally used in conjunction with a paddle blank (see Figure 1).

1.3 Referenced Publications The latest edition or revision of the following standards

or specifications shall, to the extent specified in this standard, form a part of this standard.
