Pipeline cleanliness improves product quality, and operating efficiency and mitigates debris-inflicted damage to plants such as compressors. From the day the pipeline is constructed it will need cleaning with pigs to remove weld slag, hydro test water, and general construction debris such as welding rods. As pipelines ages, debris such as scale, wax, and other deposits will accumulate. Operational and product conditions that encourage corrosion can affect the useful life of the pipeline and affect system integrity.
Knowledge of what is in the pipe, the rate of debris deposition of debris, and where the problems originate, together with an understanding of the general pipeline design is invaluable for developing an effective cleaning & maintenance program. Major failures can be avoided with regular maintenance.
When it comes to pipeline applications, whatever is pumpable can also bring things to a halt. From unwanted debris buildup or a complete blockage, the best way to overcome pipeline flow issues is pigging. At Inline Services, we produce pigging and liquid product recovery equipment that boosts production capacity by improving flow rates while reducing downtime and waste. Here’s a breakdown of the different types of pigs and the pipeline applications they benefit.
Inline Services is a leading manufacturer of pigging devices and product recovery systems for demanding applications. We deliver safe and effective custom solutions for your application from design and manufacture to implementation and upkeep.
In large pipelines with ultra high velocities, operators are reluctant to reduce flows down for pigging, as this results in a reduction of revenue generating delivery. We have designed bypass pigs specifically for these circumstances which can react to changes in speed and automatically slow down or speed up.
Inline Services manufactures pipeline pigs designed for new pipeline construction, cleaning and commissioning.
Corrosion is inevitable within a pipeline, however taking a proactive approach to preventative maintenance can save you thousands, if not millions of dollars in repair, replacement, or environmental clean-up costs.
Inline Services has designed pipeline pigs that aid in both the prevention and removal of black powder.
Crude oil and gas condensates contain varying amounts of wax or paraffin.
Inline provides a number of aggressive pigs for use in pipeline corrosion control, including brush designs to address pitting caused by bacterial corrosion.
Maintaining a routine pigging program will keep a pipeline in good condition, maintain optimal flow and reduce damage to plant and avoid eventual failures.
We specialize in gathering intelligence about the internal condition of the pipeline and determining efficient maintenance programs.

Simple Pigging System with Drop-Out
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.
