Part 4 is displayed. As shown in the figure, this “GB standard selection screen” includes main material data relating to a steel pipe material (main steel pipe material) defined in the JIS standard as “SUS304HTB” and an equivalent steel pipe material corresponding to the main steel pipe material in the GB standard. Corresponding display is performed by arranging the equivalent material data of the above and below.

  More specifically, on the “GB standard selection screen”, the chemical composition of the main steel pipe material and the equivalent steel pipe material, the yield point and the tensile strength, etc. relating to the strength of the main steel pipe material and the equivalent steel pipe material are displayed in a vertical contrast. A display field is provided. That is, this “GB standard selection screen” is displayed so as to make it easy to grasp the chemical composition and strength relativity regarding the main steel pipe material and the equivalent steel pipe material. FIG. 4 shows an example in which two equivalent steel pipe materials corresponding to GB standard number “GB13296-91” and GB standard number “GB9948-88” correspond to the main steel pipe material of JIS standard number “SUS304HTB”. Yes.

  When the display calculation unit 3 detects that “SUS304HTB” is selected and specified by the operation unit 1, the display calculation unit 3 searches the display element data in the storage unit 2 using “SUS304HTB” as a search condition, thereby displaying the display element corresponding to “SUS304HTB”. Data is acquired, and the display element data is applied to each display field to generate image data of the “GB standard selection screen” and output it to the display unit 4. As a result, the display unit 4 displays “GB” shown in FIG. “Standard selection screen” is displayed.

  Here, on the “GB standard selection screen”, as shown in FIG. 4, a size display button for instructing display of a size related to each equivalent steel pipe material is displayed.
