We offer a full range of pre-commissioning services and is becoming the service-provider of choice for pipeline construction companies looking for reliability, safety and quality. The limits of the pipeline pre-commissioning activities are from pig launcher to pig receiver and include all in-line valves, flanges and fittings.
• Filling using forced flooding or free-filling methods.
• Cleaning using chemical or mechanical methods that removes deposits or debris to ensure optimum flow and efficient throughput.
• Gauging that detects any internal restrictions and gives indicative results as to whether the pipeline is geometrically suitable for the progression to more aggressive cleaning pigs. Gauging is achieved by fitting a pig with an aluminum plate, sized to approximately 90% of internal pipeline diameter. This is carried out to prove the dimensional quality of the internal diameter of the pipeline
• Hydro-testing is performed to expose defective materials that have missed prior detection, ensure that any remaining defects are insignificant enough to allow operation at design pressures, expose possible leaks and serve as a final validation of the integrity of the constructed system.
• Dewatering and Swabbing using advanced compression and dewatering train designs to leave the minimal residual water.
• Drying using forced air to lower the internal dew point of pipeline. This avoids hydrate formation when pipeline is put into service by using the blower.
• Purging using nitrogen to effectively and completely purge the pipeline prior to commissioning, capping or abandonment. The mobile nitrogen unit is considered for this purpose.

For pipeline pigging, cupped or foamed pigs with swabs, abrasive materials or wire brushes are pushed through pipes to remove debris, sand, loose coatings, rust, and scales. With pig train technology, several foamed pigs with different chemical solutions in between are pushed through pipes for special cleaning purposes.
• Ideal for long pipeline and multiple bends
• Environmentally friendly and minimizes waste
• Shorter cleaning time
• Steam pipeline
• Gas pipeline
• Water pipeline
• Hydrocarbon pipeline
• Transfer pipeline
