The efficient operation of pipelines transporting liquid or gaseous hydrocarbons is crucial. Any upset to the internal pipe surface can significantly impact both pipeline throughput and energy requirements for maintaining design flow rates. Maintaining a clean pipeline will help to maximize flow, will increase system longevity, will enhance system reliability while lowering associated safety risks and will, ultimately improve bottom line profitability for pipeline owners and operators.

Throughout the operational life of pipelines, it is common to encounter deposits, including a buildup of sand, scale, wax, asphaltenes, black powder, hydrates and emulsions which can create flow restrictions, bore reductions, higher back pressures and accelerated corrosion.

Pipeline group deliver a wide range of specialized pipeline cleaning solutions planned to address any of these problems. Services include the following:

• Pressure Testing: N2 is more effective to find leaks in the (gas lines, plants piping system & vessels) before they put them back into operation.
• Purging – Cutting/Welding:  Displacing Pipelines with N2 gas to remove Oxygen, to prevent corrosion & to fill the line with inert gas for Cutting / Welding operation.
• De-watering & Drying: Displacing Pipelines with N2 gas, to remove water after testing. This procedure also include heating up N2 Gas Temp, to the max. to remove moisture from inside the line till reaching the required dew point.
• Cooling Down piping / vessels system -To cool down system in plants, when they reach Max Temperature.
• Water Filling & Hydro testing-To test for any leaks, pressure is built up through water filling.
• De-cruding-To remove residue oil using N2.
• De-gassing: Displacing Pipelines with N2 gas, to remove gases (H2S).
