Hello, teachers! How should the statement in paragraph 1 of clause 4.1.3 on page P173 of HG/T20582-2020, which reads \"The distance between the edge of the weld at the opening and the edge of the butt weld on the shell should be less than di/6, or at least the smaller of twice the shell thickness and 40 mm\", be understood? Why must it be less than di/6? Is it a typo?
It must be a typo; \"not less than\" is the logical choice
