Description

A kind of pipeline measurement method and its device

technical field

The invention belongs to the technical field of pipeline measurement, in particular to a pipeline measurement method and a device thereof.

Background technique

In order to avoid dimensional problems during on-site installation, which may cause normal installation, delay the on-site construction period, and increase some unnecessary losses, it is necessary to measure the size of each pipe before leaving the factory to ensure that the size is within the tolerance range. If you encounter a pipeline that is not 90 degrees during pipeline measurement, it will be more troublesome to measure the end face to the center of the elbow. You need to find the center of the elbow to measure accurately. The specific operation is to first place the entire pipeline horizontally, and then find Find the center line of the pipes on both sides, connect the center lines to find the center of the elbow, and finally measure the size from the end face to the center of the elbow. , it is easy to cause errors.
