How to handle Micro Bore Hose blocked by impurities?

Micro Bore Hose realizes gas and water supply through micron-sized micropores on its wall. Due to small pore size, sediment impurities, suspended solids in water, algae dirt and soil particles easily accumulate and cause micropore blockage after long-term operation. Blockage leads to reduced gas and water supply, uneven gas and water output, and even partial pipeline failure in severe cases. Blockage treatment follows the principle of simple flushing first, then deep cleaning and finally preventive maintenance. Adopt corresponding solutions according to blockage severity to dredge the hose and restore its performance.

Mild surface blockage is the most common type, characterised by slightly reduced gas and water output of the hose without fully closed micropores. Blocking substances are mostly floating dust, fine sediment and loose algae, and pipeline disassembly is unnecessary. Shut down equipment valves first and inspect the overall pipeline integrity to confirm no damage or air leakage. Boost water or air pressure slowly and maintain high pressure for continuous flushing for 3 to 5 minutes. High-pressure water and gas flow scours loose impurities on the pipe surface and dredges slightly covered micropores. Gently rub the pipe surface during flushing to assist dirt detachment. After flushing, check gas and water output of micropores. Uniform and smooth flow indicates successful dredging. This high-pressure flushing method can handle mild blockages and serve as a routine preventive maintenance measure.

Moderate shallow blockage is characterised by weak gas and water output in partial pipelines and partially closed micropores. Blocking substances include solidified sediment, viscous biofilm and organic residues. Simple high-pressure flushing cannot remove them completely, so pipeline disassembly and segmented cleaning are required. Cut off gas and water supply first, drain accumulated water inside the pipeline, remove pipe joints and lay segmented hoses flat. Prepare clean water together with soft brushes, sponges and other flexible tools. Steel wire brushes, hard iron wires and other hard tools are prohibited to avoid scratching pipe walls and permanently damaging micropores. Wipe the inner and outer walls of each pipe section section by section, focusing on cleaning biofilm and dirt in areas with dense micropores. After wiping, soak the hose in room-temperature clean water for 10 to 15 minutes to soften stubborn attachments, then conduct high-pressure flushing again until all micropores deliver uniform gas and water without dead corners. Dry the hose and reconnect the pipeline for operation.

After dredging, long-term prevention is the key to reducing repeated blockage. Perform simple high-pressure flushing once a week in daily maintenance to remove loose surface impurities, and conduct full pipeline inspection and deep cleaning every month. When equipment shuts down and remains idle, drain all water inside the pipe, lay it flat and dry it for storage to avoid stagnant water breeding algae and bacteria. For use in aquaculture and sewage scenarios, improve water quality regularly to reduce suspended solids and organic matter content. For agricultural irrigation scenarios, install filtering devices at water inlets to intercept large-particle sediment impurities, lower blockage probability from the source and extend the overall service life of Micro Bore Hose.
