As part of the final commissioning process for a newly constructed building in Dammam, Eastern Province, Saudi Arabia, WJ supplied one of its latest Atlas Copco PAC108 pumps to a specialist flushing contractor. The pump was used to flush and clean the completed pipelines, ensuring they were free of debris and contaminants before the building’s systems became operational. With its high capacity and efficiency, the PAC108 provided a reliable and effective solution to achieve the required flushing velocity.
At WJ, we have invested in a new fleet of specialist pumps for Saudi Arabia, including models from Atlas Copco and Pioneer. Our goal is to provide clients with the most suitable pumping solutions, ensuring high operational reliability while maximizing fuel efficiency—helping clients save costs during operation.
The Importance of Pipeline Flushing
Flushing is a critical process in the commissioning of new pipeline systems. It removes construction debris, rust, dust, grease, and other contaminants, preventing damage to the main system pumps and improving overall operational efficiency. The process involves pumping fluid at a specific velocity to create friction, which cleans the pipes.
At the pipeline’s outlet, filter pods equipped with filter bags capture the removed debris. The filter mesh size, typically ranging from 20 to 1 micron, is selected based on the required level of cleaning.
For district cooling pipeline systems, a flushing velocity of 2 to 3 m/s is typically targeted to ensure effective cleaning. Chemical additives can also be introduced to enhance the cleaning process. In larger systems, where pipeline diameters and lengths are significant, the system may be flushed in sections to control pump requirements and pressures efficiently.
For existing operational pipelines, hot tapping may be required to connect to live pipelines. This method is commonly used to remove debris buildup and residues that can impact the efficiency of pipelines and heat transfer systems.
