    • The pigs can also break apart

      Pigs can even break apart into pieces in the pipeline. Recovery of a broken piece is a problem, but a second problem. The first problem, I think, is to find the broken piece is stuck.

      I have read a piece about a "scraper pig" breaking into pieces in the 800-mile long Alaskan pipeline. :

    • Here is some good info on pigs

      Hi guys...

      Found a pig manufacurer's site which gives more information on pigs : <link removed>
      They divide pig tasks into 3 categories :
      Utility pigs
      In-line inspection pigs
      Gel pigs

      They have divided utility pipeline pigs into two groups based upon their fundamental purpose:
      Cleaning pigs
      Sealing pigs

      Then there are various types or forms of pigs :
      Mandrel pigs
      Foam pigs
      Solid cast pigs
      Spherical pigs

      There is more at the site.
