Vertical dimensions or pipe lengths are calculated using elevations, while horizontal measurements are computed using north-south and east-west coordinates.

Calculations for pipe lengths were done using coordinates and elevations.

Piping isometrics are drawn on a specific paper, which has lines forming equilateral triangles of 60°.

The next big thing that you should focus on learning and gaining knowledge about is how to read an isometric drawing.īut before wrapping up, let us highlight some key points related to piping isometric drawings.

Represents a Stress Analysis model built up for reference to determine final stress markup to update the stress requirements.

marking up deviation during site modifications.

Isometric drawings for piping are commonly used for: Uses of Isometric drawing in Piping Engineering services Piping Isometric drawings are favoured in online course for piping engineering because they are efficient yet straightforward while conveying complex information. Descriptions of Piping and Component with size, quantity, and material codes.Important information to note from Piping isometric drawingsĪ piping isometric drawing provides all the required information like: One can find the original dimensions specified in the Bill of Material, tagging, call-out, or notes.

Pipes are primarily shown in the same size.

Pipes are usually drawn using a single line irrespective of the different line sizes and the other configurations such as reducers, flanges, and valves.

It is not drawn to the exact scale measurement, but it is proportionate with exact dimensions represented.

Let’s check some notable distinguishing features of isometric drawings. Generally, isometric drawings are a 2d representation of 3d piping designs. This is because the transferred information should be adequate through the process through which the piping should relate to other elements, with exact dimensions and other parameters in place. If we look at the criticality of isometric drawings in oil and gas courses for mechanical engineers, it is magnificent. So, the 3d model is sketched on paper by compressing its dimensions so that the assigned personnel can easily understand all its necessary parameters. Usually, 3d models cannot be understood by the personnel at the fabrication and construction site. However, another segment of drawing deals with the replication of 3d models that the members can understand at a construction site. In P & ID, it was mostly about piping design. In the previous blog on P & ID drawings, we have discussed only a segment of engineering drawing necessary in the oil and gas industry.
