Pipe clamp connector design / analysis (to ASME VIII…)

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

Hub and clamp or ‘Grayloc’ type pipe connectors may be designed and analysed in accordance with ASME VIII Div. 1 Appendix 24.

Design input

Input is similar to the pipe flange design program, with:

  • input data panels (see right, top & below) specific to the pipe connector hub, clamps, bolting, and gasket. Bolt spacing may be varied within allowable limits.
  • internal pipe pressure, connector bending moment, and pipe axial force inputs

Connector analyses output

  • Full code comparison stress results are presented.
  • A scale section plot, views of the clamp, and additional calculated data may be viewed (as right, below). The scale plots enable the design to be visualised and a better finished product obtained.

Analysis support

  • Example analyses
  • Integral database of commonly available pipe sizes, with automatic input of selected pipe data
  • Extensive help files: explanatory notes and comments on many of the key inputs; comments on different calculation methods, where appropriate; gasket characteristics and data, from ASME VIII; bolt areas, by size
  • Scientific calculator
