Expansion Loop Design and Analysis

Pipemill: for the design, analysis and layout of piping components

  • Four typical expansion loop types are available.
  • Data bases for standard pipe size and wall thickness and expansion characteristics may be accessed, or user data entered.
  • Displacements, stresses and end loads are calculated.
  • Allowable stress is calculated in accordance with ASME B31.3 and any over-stress will be clearly flagged. The calculation is based on a stiffness matrix and results compare well with commercial stress analysis packages.
  • Iterative runs may be performed to optimise loop size.

Analyses support

  • Example analyses
  • Explanatory notes and comments on each set of calculations
