Note: 1 In the table, the red area, green area, purple area is available for specifications, orange area is available but no performance area, and white area is not available for specifications.

2. The red area is to expand the specifications, which need to consider the influence of ultra-thin-walled rolling tearing and the "inner six-square" of small outer diameter thick wall, which needs to be reviewed; The purple area is a limited size and requires review.

3. The "x" sign in the table is a single ruler, and the production economy needs to be considered.

4. The wall thickness in the table is the rolling wall thickness range, and when ordering non-nominal wall thickness, it is necessary to calculate the rolling wall thickness according to the wall thickness tolerance to confirm whether it is a available specification;

5. No specifications for orange areas and outer diameters in the table require the development of new hole patterns and need to be reviewed.
