Pigging After Construction
Pigs are used after construction to remove debris left in the line when it was assembled; for removing stubborn debris, such as millscale and weld bead slag from the pipe wall; initial gauging to determine there are no obstructions and ensure that the ovality is within acceptable limits; and geometry or caliper pigging for measuring and recording any obstructions.

This is a brief sequence of pigging after construction of a pipeline:

  1. Debris Removal
    (Clear Construction Debris)
  2. Gauging
    ( Detect dents & buckles)
  3. Cleaning
    (Remove rust, dirt & mill scale, add corrosion inhibitor)
  4. Flooding
    (Flood prior to hydrotest)
  5. Hydrotest
    (Test the pipeline integrity)
  6. Dewatering
    (Displace water with air, N2, chemical and product)
  7. Air/Vacuum Drying
    (Drying the pipeline)
  8. Line Packing/Nitrogen Packing
    (Preserving the pipeline using N2)
Pigging During Operations
 
During pipeline operation, pigging is require in case of:
 
  1. To separate products
    ( Multi products lines, dewatering)
  2. Improving flow efficiency
    (Removal of sand and wax from oil lines, clearance of dirt and condensate from gas line)
  3. Corrosion inhibitor
    ( Batching with inhibitor, water drop-out removal)
  4. Meter proving
    (Calibration of Flowmeter)
