Sigma offers a comprehensive design, manufacture and calibration service for pipe assembly build fixtures.

Our engineers can use customer supplied CAD model data or master pipes to design and model bespoke fixtures for both building and interchangeability checking of rigid pipes. The fixtures are manufactured, usually in aluminium, in our tool-room and calibrated using a CMM.


  • Robust aluminium construction

  • Manufactured and calibrated to original CAD coordinates

  • Dual purpose: assembly aid and ICY validation
