How to mark the welding joint of such a pipeline? At what distance should we mark a welding joint?
The welding spots are determined according to the installation size needs of the pipe fittings and the pipe transportation needs, and are not evenly distributed.
The welding number is generally not marked on the design drawings. When the construction unit receives the drawings and before starting work, the technical staff will prepare a unified welding number. For straight pipes (without socket welding), there are no pipe fittings in the middle and direct butt welding connections. According to the length of the pipe, it is not appropriate to add a welding port to 6 meters.
