Inspection Pig is an indispensable tool for cleaning the total hard coke deposits formed in the inner surface of the furnace tube(coil). This replaces conventional cleaning of furnace tubes either by chemical or combustion method.

Standard Features
  • These pigs are fitted with pins uniformly studded around the surface of the pig so that during travel through the length of the tube, they scrape the hard coke deposits from the inner surface of tubes and coils.
  • As the coke deposits are removed, bigger size pigs are used for further scrapping of the coke till all the coke deposits are removed.
  • This ensures safe deposits removal in a short time without damaging the tube (coil).
