The residual stress of the pipe has a great influence on the dimensional accuracy of the pipe, so it must be tested.

However, after clamping and fixing, when the detection head used for stress measurement needs to measure different angles of the long-distance pipeline, the long-distance pipeline cannot be rotated. Therefore, the long-distance pipeline needs to be loosened from the clamp, and the long-distance pipeline needs to be rotated to adjust the angle and then fixed again before measurement can be performed, which makes the operation more complicated.
