How to look at the pipeline?

First of all, a general understanding,

Firstly, the view configuration, quantity and expression content of each view of engineering pipeline are summarized. And initially understand the meaning of legend and code, as well as the drawings of non-standard pipe fittings and pipe racks. Then browse the equipment project number, nozzle list, construction requirements and plans of different elevations, etc.

Second, layout analysis,

First of all, according to the process sequence and pipeline number, find out the equipment number and nozzle of the starting and ending points of the pipeline one by one. And according to the projection relationship, expression, graphic symbols and relevant regulations of the floor plan, find out the inlet and outlet, branch and installation position of each pipeline, as well as the types and arrangement of valves, fittings, instruments and pipe racks;

Third, size analysis,

By analyzing the dimensions in the pipeline layout, we can understand the positioning of pipelines, equipment, nozzles and fittings. , and the mutual distance relationship between them. By analyzing other marks, we can know the process materials, pipe diameters, valve models, pipe fittings specifications, installation requirements, etc.

Extended data:

Classification of pipeline engineering drawings:

First, according to the professional division:

1, industrial pipeline and industrial equipment installation project.

2, sanitary pipes, construction and installation projects (building water supply and drainage pipes, heating pipes, gas pipes, ventilation and air conditioning pipes, fire pipes, etc.). ).

Second, according to the graphics and functions:

Basic drawings: drawing catalogue, design and construction instructions, equipment and materials list, process flow chart, plan, axonometric drawing (system drawing), elevation drawing and section drawing, node drawing, detailed drawing and standard drawing (also called standard atlas).
