Project piping design is based on many calculations. Project pipe classes are designed based on the relevant calculation codes. The E80 software uses the EN 13480-3 for the internal and external pressure calculation of pipe and fittings. The difference with PCC EN 13480-3 calculations is that the output includes the information about intermediate results and the flow of calculation.

The E80 application can be used to study the code calculations for different design conditions, materials of construction and component dimensions. The tool is used for engineering training as conducted at InIPED, the International Institute of Plant Engineering and Design.

The application has in addition to regular calculation reports an unconventional output: it can show a detail report how every formula is passed and what the input/output is. This is very useful when for example an iteration is done to get a solution. The validation of each calculation is a separate report with a summary and the detail in- and output.

The dimensions entered are shown in a dimensional sketch to scale. The sketch can be exported to DXF format for further use in a CAD application. The sketch has a tool to measure dimensions when the engineering is working on the calculations.

The E80 application is made for Notified Bodies, Authority Approval Companies, for code calculation development, researchers and those engineers who are interested in the minute details of the calculations.

Proper engineering calculations include the validation of the dimensional input of the pressure components being calculated. The assessment based only on values is sometimes difficult due to interpretation or just the amount of dimensions to be checked. The most efficient assessment is done to use a sketch representing the dimension input to scale to the user.

The dimensions entered in E80 are therefore shown in a dimensional sketch to scale. This sketch can be exported to DXF format for further use in a CAD application. The sketch has a tool to measure dimensions working with the calculations. The dimensions can be checked in the CAD application but also the calculated material and pressure areas, which are regularly used in the calculations.

Although the EN 10253-2 is a dimensions standard, it contains calculation for internal pressure of elbow, tee, reducer and cap of the standard. The calculations are based on the EN 13480-3 but do not always give exactly the same results as the EN 13480-3.

The EN 10253-2 calculations have been added to the E80 application. The purpose is to be able use the calculations when necessary and to do comparisons with the EN 13480-3 calculations.
