This service “detailed pressure drop calculation for pipelines” includes the calculation of the pressure drop for a pipeline in the stationary case.

The above-mentioned “detailed” calculation means that a detailed calculation takes place for the individual pipeline sections of the pipeline under consideration on the basis of isometrics.

This service includes the calculation of the pressure drop for:

· 1 pipe, maximum 20 bends, max. 10 different sections in one isometry of the same pipe

· inpatient case

· The documentation takes the form of a short report, there is no presentation

· Maximum one revision


Support by the client

The client shall provide all documents required for the performance of the investigation in up-to-date form. The processing period of two weeks (14 days) does not begin until all necessary documents have been handed over to horst weyer und partner gmbh.

Overview of the required documents:

  • Complete and up-to-date isometrics of the pipeline, alternatively true-to-scale 3D pipeline design in *.dwg-format
  • Number of fixtures and fittings (calculated with database standard)
  • Characterisation of the material flow in the pipeline (volume or mass flow, temperature, outlet pressure, density and viscosity as well as the substances involved).
  • Conditions at the outlet of the pipeline

Boundary conditions and exclusions

The fee quoted is based on the following boundary conditions and exclusions:

· The detailed pressure drop calculation for pipelines based on the isometrics for up to 10 sections of the same pipeline (sections have different nominal diameters, for example).

  • There is no on-site appointment.
  • The calculation is based on the stationary case, there is no dynamic calculation for changing operating parameters.
  • Pressure drop values based on standard installations as well as standard values for pipelines from weyer database
  • The results are handed over as a short report, there is no presentation.
  • No editing of drawings required
  • Occurring substances are contained in the internal database.

Processing will not begin until the required documents have been received. Feel free to send them to us via the chat window below.
