Waterworks main-pipe cleaning: a Jinjie J-5022D custom equipment case

The site problems to address

• Access and tool positioning inside the pipe are limited
• Hose length, fittings and attachments affect tool-end pressure and flow
• Coordinate hose handling, discharge and work sequencing

Allocate equipment and consumables by task

From custom equipment to site operation

Power, hose deployment and the in-pipe tool were specified as a system to support equipment selection, operation and maintenance on the water main.

For this waterworks main, Wanshenglong paired the Jinjie J-5022D with the hose system and a dedicated in-pipe cleaning tool.

Positioning an in-pipe tool from outside the main

Inside a water main the operator cannot freely adjust spray distance and angle. Check the pipe material, bore, length, access openings, bends and the space available to feed and retrieve the tool before laying out the hoses and operator station.

Wanshenglong selects the cleaning unit and end tool together. For a tool fed through an access opening, check the dimensions, connections and retrieval method before ordering the power unit.

Delivering the required pressure to the tool

Long hoses, fittings and attachments affect pressure and flow at the tool. Two installations with the same pump outlet figures can perform differently. Detaching deposits also requires enough water to carry them out.

For this installation the J-5022D supplies the cleaning power. Pressure, flow, hose length and fittings must work together to deliver the required conditions at the tool.

Deploying and retrieving long hose runs

Plan where the hose will run, how it will be kept orderly and how it will be retrieved. A tangled hose is harder to reel and makes damage or connection problems harder to spot.

A wheeled in-pipe tool uses a frame and support wheels to position the cleaning attachments. A high-pressure hose connects the power unit to the tool. The trial footage shows them operating together.

Removing the material after it is loosened

Plan how rinse water and loosened material will leave each section. Coordinate the discharge point and site controls with the cleaning operation. Water mains also require the project operator’s flushing, disinfection and return-to-service procedures.

Planning covers the water supply, hose run, attachments and discharge. The project operator coordinates cleaning and return to service under the applicable procedures.

Specifying a complete system around the power unit

The J-5022D project combined the power unit, hose management and cleaning attachments, from duty assessment and design through assembly and trial operation.

Review drive, pressure, flow, hose and attachments against the actual task. This helps procurement, operators and the maintenance team agree what to order and how it will be supported.

Start with the conditions at your site

For a waterworks main, industrial pipe or specialist cleaning task, give Wanshenglong the pipe material, bore, length, deposits, access and water supply. These details help establish the Jinjie equipment and attachments to include in the specification.
