Project details


Task:

  • Monitor gaseous and aerosol-bound substances
  • Isokinetic collection of samples
  • High requirements placed on interior pipe surfaces (Ra < 10 µm)
  • Almost gapless connections
  • Prevent the build-up of condensate

Solution:

Use special flanges with a fitting accuracy of around 1/100. Use suitable pipes whose interior surface is electropolished or treated with Teflon. Install a pipe trace heating system to prevent the build-up of condensate.
