Calculator Description
Pipe Strength Calculator v1
The pipe strength calculator is used to calculate the behaviour of a pipe with closed or open ends including: buoyancy filled or empty, internally or externally pressurised, applied moments and forces and includes temperature effects

Pipe Strength

Subject

A pipe is used to transport fluids from one location to another.

Its ability to do this safely depends upon its capacity to cope with its operational environment and end constraints.
I.e. buoyancy, internal and external relative pressures, end conditions (open or capped) and externally applied loading (forces, moments, etc.), all of which will generate primary and shear stresses in the pipe wall.

These primary and shear stresses must be combined for the purposes of fatigue and design.

Calculator

The pipe strength calculator determines the reactions on a pipe due to its internal and external environment and loading conditions.

Whilst Pipe is very comprehensive, it is unnecessary to complete all input data if you are only looking for specific outputs, such as hoop stress or buoyancy for which guidance is provided in the technical help page.

The pipe strength calculator provides the structural properties of the pipe, along with stresses, forces, buoyancy and physical distortion resulting from the above conditions.

The output data from Pipe can be exported to CalQlata’s Combined Stress calculator where the combined stress at your designated radius will be calculated.

For help using this calculator see Technical Help

Pipe Strength Calculator - Options

The input and output data are the same for both calculation options in Pipe :

You enter: and the pipe strength calculator will provide:
  • Internal diameter
  • External diameter
  • Density of the internal fluid
  • Density of the external fluid
  • Density of the pipe material
  • Young’s modulus of the pipe material
  • Poisson's ratio of the pipe material
  • Internal pressure
  • External pressure
  • Bending moment
  • Shear force
  • Torsion
  • Temperature variation
  • Linear expansion coefficient
  • Radius at which you would like to know the stress
  • Added mass
  • Mass of the pipe (per unit length), incl. added mass
  • Mass of the fluid inside the pipe (per unit length)
  • Buoyancy (per unit length)
  • Cross section area of the pipe wall
  • Cross section area of the pipe bore
  • Second moment of area
  • Polar moment of inertia
  • Hoop stress
  • Longitudinal stress
  • Radial stress
  • Bending moment stress
  • Shear stress from pressure
  • Shear stress from shear force
  • Shear stress from torsion
  • Shear stress from pressure and bending
  • Change in internal diameter
  • Change in external diameter
  • Change in length ('Closed Ends' only)
  • Axial force (pressure) ('Closed Ends' only)
  • Axial force (temperature) ('Closed Ends' only)
  • Axial force (total) ('Closed Ends' only)

Open Ends

Both ends of the pipe are open thereby eliminating direct longitudinal stress & growth and end cap forces.

No Axial Growth

Both ends of the pipe are open but longitudinal growth is stopped thereby inducing direct longitudinal compressive stress and end cap forces.

Closed Ends

Both ends of the pipe are closed thereby inducing direct longitudinal tensile stress & growth and end cap forces.
