Piping System Calculations

Pressure loss calculation

Individual calculations for pipes, partial resistances, geodetic height and energy balance for compressible and incompressible fluids.

  • Enhanced flow resistance database according to I. E. ldel'chik “HANDBOOK OF HYDRAULIC RESISTANCE“
  • Pressure loss with NPSH calculation 
  • Graphical support

Support of two-phase flow conditions according to three different calculation methods:

  • L. Friedel “Improved friction pressure drop correlation for horizontal and vertical two phase pipe flows” European two phase flow group meeting, Ispra, 5-8 June 1979
  • H. Müller-Steinhagen – K. Heck „A Simple Friction Pressure Drop Correlation for Two-Phase Flow in Pipes” Chem. Eng. Process., 20 (1986) 291-308
  • Homogeneous flow model

Pressure surge

  • Calculation for single-run piping systems which end with a control valve, as a function of the closing time and the valve characteristic
  • Valve database and graphical support

Sizing

  • Calculation of basic values, such as the surface area, volume, flow velocity and Joukowsky peak

Pipe wall thicknesses

  • Calculations optionally according to:

EN 13480 (2002)
ASME B31.3 (2016) 
DIN 2413 (2011)
DIN 2413 (1993)
DIN 2413 (1972)

  • Pipe bends with or without a constant wall thickness can be calculated for pulsating and static loads in addition to straight pipes
  • Pipe materials in accordance with EN 13480:2002 can be selected from a user extensible Material Database and you can also calculate all relevant parameters, such as tensile strength, creep rupture strength and yield strength.

Pipe compensation

  • Calculations for L and U-bends, changes in length, pipe support loads and stress limits

Span calculation

  • Calculation of the individual weights (pipe, medium, insulation)
  • Span calculation taking account of sag
  • Pipe materials in accordance with EN 13480:2002 can be selected from a user extensible Material Database
