[0023] like Figures 1-2As shown, a convenient tool for measuring the wall thickness of pipes and plates and the inner diameter of small pipes is provided. The tool has a front and a back, with a horizontal edge I1 at the top and horizontal edges II2 and III3 at the bottom. One end of horizontal edge I1 is connected to an outer beveled edge 4, and the other end is connected to an outer straight edge 5. The outer straight edge 5 is connected to one end of horizontal edge III3. The end of the outer beveled edge 4 is connected to a short straight edge I6, and the bottom end of the short straight edge I6 is connected to one end of horizontal edge II2. The other end of horizontal edge II2 is connected to a short straight edge II7, and the top end of the short straight edge II7 is connected to an inner seam beveled edge 8. The top end of the inner seam beveled edge 8 is connected to an inner seam straight edge 9, and the bottom end of the inner seam straight edge 9 is connected to the other end of horizontal edge III3. The inner seam beveled edge 8 and the inner seam straight edge 9 on the front side are symmetrically marked with the numbers 1 to 8 (I). The outer beveled edge 4 and the outer straight edge 5 on the back side are symmetrically marked with the numbers 15 to 50 (II). A hole I10 is provided near the horizontal edge I1 and the outer straight edge 5. A hole II11 is provided near the short straight edge I and the horizontal edge II2.

[0024] The tool has a thickness of 2mm, a top length of 13.5mm, and a total bottom length of 50mm.

[0025] The length of the shorter straight side II7 is less than the length of the shorter straight side I6.

[0026] The length of the inner seam straight edge 9 is less than the length of the outer straight edge 5.

[0027] The length of the outer straight edge 5 is 80mm.

[0028] The length of the inner seam bevel 8 is less than the length of the outer seam bevel 4.

[0029] The length of horizontal side Ⅲ3 is less than the length of horizontal side Ⅰ1, and the length of horizontal side Ⅰ1 is less than the length of horizontal side Ⅱ2.

[0030] The length of horizontal side I1 is 13.5 mm.

[0031] Holes I10 and II11 have a diameter of 3mm, making it convenient for users to hang them on keychains, thus making the tool easier and faster to use.

[0032] This utility model is made of 2mm thick stainless steel, which has high hardness and is not easily damaged.

[0033] This invention is suitable for measuring the wall thickness of pipes and plates with a diameter of 1-8 mm, as well as small-diameter pipes with an inner diameter of 15-50 mm.

[0034] The front side of this utility model is used to measure the wall thickness of pipes and plates.

[0035] When measuring the thickness of a sheet material, place one side of the sheet material firmly against the inner straight edge 9 of the tool and slowly move the tool forward. When the tool can no longer be moved, press the other edge of the sheet material tightly against the inclined edge 8 and read the scale reading at this fixed position. This scale reading is the thickness of the sheet material. When using this tool, it is necessary to keep it perpendicular to the sheet material at all times to ensure the accuracy of the measurement.

[0036] When measuring the wall thickness of a pipe, place the outer diameter surface of the pipe firmly against the inner straight edge 9 of the tool and slowly advance the tool forward. When the tool can no longer be moved, ensure the inner diameter edge of the pipe is tightly against the inclined edge 8 and read the scale reading at this fixed position. This scale reading is the wall thickness of the pipe. When using this tool, always keep the horizontal edges II2 and III3 of the tool parallel to the center line of the pipe diameter to ensure measurement accuracy.

[0037] The reverse side of this invention is used to measure the inner diameter of small pipes.

[0038] When measuring the inner diameter of a pipe, place the inner diameter surface of the pipe firmly against the outer straight edge 5 of the tool and slowly advance the tool forward. When the tool can no longer move, the edge of the inner diameter surface of the pipe should be tightly against the outer beveled edge 4, and the scale reading at this fixed position should be taken. This scale reading is the inner diameter of the pipe. When using this tool, it is necessary to keep the horizontal edges II2 and III3 of the tool parallel to the center line of the pipe diameter at all times to ensure the accuracy of the measurement.
