Less than six times, and not less than 100 mm
The bending radius of the elbows used on-site for pipes should not be less than 3.5 times the outer diameter of the pipe； The distance from the weld to the starting point of the elbow should be (not less than the outer diameter of the pipe), and it must also be at least 100 mm.
030. The bending radius of pipes when bent on-site should not be (less than or equal to 5 times) the outer diameter of the pipe； The distance from the weld to the starting point of the elbow should be (not less than the outer diameter of the pipe), and it must also be at least 100 mm. Should the words “not appropriate” be removed? This post was last edited by zhangcwzj on 2009-3-18 17:02.]
