Consideration of countermeasures for water pipe internal camera inspection.

There are various methods, such as using friction from brushes, as countermeasures for water pipe internal camera inspections.

In the "pipe cleaning method," cleaning of the pipes is carried out using drainage pipes and fire hydrants. To clean effectively, it is necessary to maintain an internal flow rate of about 1 meter per second. Additionally, in special pipe cleaning methods, physical tools such as pigs are used to frictionally clean the inner surfaces of the pipes and discharge foreign objects, as well as methods that use frictional forces from brushes to efficiently remove debris inside the pipes, and methods that utilize the shear force of slag flow. The "Water Pipe Internal Camera Survey Handbook" introduces various methods for consideration of countermeasures. [Countermeasures] ■ Special pipe cleaning methods ■ Soft pig cleaning (SCOPE method) ■ High-speed carbonated water cleaning (HS method) ■ High-pressure jet cleaning with rotating brushes (TS method), etc. * For more details, please refer to the PDF materials or feel free to contact us. * This PDF material is a digest version.
