In order to solve the difficult problem of an intersection-line Underlining of two pipe crossing in the engineering field

A device of realize the synchronous underlining function of branch pipeline intersection-line and main pipeline intersection hole is developed. Specifically

it is a device to realize the function of fast and synchronous marking of branch pipe intersecting line and main pipe intersecting hole by manual operation and using profiling principle. The device has the characteristics of high accuracy of underlining

easy operation

low manufacturing cost

strong universality and reusable. It is suitable for marking intersecting lines and intersecting holes of small and medium-sized intersecting pipelines before welding in the field of production

small batch and field construction. At the same time

It also provides a new way of thinking for the research of pipe intersection synchronization underlining

low-cost automatic cutting and welding

which has certain practical reference value.
