Pipeline Cleaning for New Pipelines

CLEANING

Newly constructed pipelines are pigged to remove construction debris such as welding rods, weld bead slag and mill scale, rust, as well as to remove hydrostatic water.  Inline Services manufactures pipeline pigs designed for new pipeline construction, cleaning and commissioning, in addition to manufacturing pigs used for drying pipelines in preparation for introduction of hydrocarbon products.

We understand that not all pre-inspection pipeline cleaning needs are the same, so we carry a variety of solutions catered to specific cleaning requirements including:

  • Low-Density Swab Pigs – dry pipelines and remove lite dust
  • Foam Disc Pigs – remove hydro-static water and debris
  • Wire Brush Pigs – achieves a high degree of pipeline cleanliness by removing  debris that could trap moisture
  • Gauging Pigs – confirms there are no restrictions in the pipeline for future running of cleaning and ILI pigs

Simple Pigging System with Drop-Out

This animation demonstrates an Inline Services VIPRS pig running through a line where a JB pig receiver unit is present. Before the pig is placed in the line the valve has been closed so that no product is present behind the VIPRS pig. As the pig moves through the line the inside of the pipe is cleaned and excess product is pushed through to the destination. Once the pig triggers the magnetic pig senor and reaches the JB receiver unit, the unit is removed with the pig inside. Once the pig is removed, the receiver is returned to the pipe.

Simple Pigging System Closure

This animation demonstrates a simple pigging system closure. Inline’s VIPRS pig is positioned in the launcher as the product is run through the pipeline. At the end of the product run, the VIPRS pig is launched to remove all product from the line. The pig will trigger the indicator to alert that the pig has reached the end of the line.

Bi-Directional Pigging

This animation demonstrates Bi Directional Pigging. Inline’s VIPRS pig positioned in the launcher as product is run through the pipeline. At the end of the product run, the VIPRS pig is launched to remove all product from the line. When the VIPRS pig reaches the JB receiver, the propelling media is turned-off. When this happens the VIPRS pig is resting at the jail bar in the JB receiver; propellant is used on the receiver side of the pig to return it to the launcher.

Automated CIP System

This animation demonstrates a fully automated VIPRS bi directional pigging process system with CIP. Inline’s VIPRS pig is first positioned in the pig launcher. The product is pumped from the storage tank to the destination. The VIPRS pig is then launched to push the remaining product to the destination and captured in the VIPRS wash chamber at the destination station. Next, the CIP solution is pumped through the line to wash the chamber and pig. Finally, the pig pushes the CIP solution out of the piping and leaving the pig clean and ready for the next product run.
