The steel pipe is curved in the length direction, and its degree of curvature is called the degree of curvature. The bending degree specified in the standard is generally divided into the following two types:
Local bending: Using a one-meter-long straight ruler, measure the chord height (mm) by measuring the chord height (mm), which is the value of local bending. The unit is mm/m, which means the method is 2.5mm/m. This method is also suitable for tube end bending.
Full-length total bending: Using a string, pull from both ends of the tube, measure the maximum chord height (mm) at the bend of the steel tube, and convert it into the length (in meters) as a percentage of the length of the tube. Long curvature.
