The single line diagram of process pipeline is not a simple plan, but a system diagram and an ISO diagram. The information contained in the single line diagram at least includes coordinates, length, elevation and nodes.
The single line diagram of process pipeline is mainly used for on-site construction and weld flaw detection. Generally, Party A or the supervisor will also require the single-line drawing of the construction party, which is usually drawn when the drawings are first reviewed at the construction site.
Direction, welding slogan, starting point, design pressure, design temperature, flaw detection ratio, etc. (The project name and work number name must be available) shall be indicated on the single-line diagram. If it is a construction drawing, it is best to draw the elevation and indicate the pipe specifications and materials.
Extended data:
Single-pipe drawing is also called pipeline axonometric drawing, pipeline single-line drawing and empty view of pipeline, and sometimes the pipe section drawing also refers to this, that is, the plane schematic annotation drawing of pipeline in three-dimensional direction.
Generally, it is necessary to mark the direction, length, diameter, material, wall thickness, and even the number of joints and anti-corrosion grade of the pipeline (the specific content to be marked depends on the actual requirements). Generally, it is drawn according to the size and elevation of the overall installation drawing, and the relevant software can automatically output the required single pipe drawing directly from the 3D model.
