Pipe cleaning

Pipe and tube cleaning is generally used to un-block pipe-work that is becoming unusable because of material build up inside it. This can be caused by scale or loose product that has collected and blocked the pipe entirely.

Tool variety

Pipe cleaning operations which utilise water jets can be performed using a variety of tools. Different tools provide capability for different types of pipe and material removal.

Tool categories

Broadly speaking pipe cleaning tools can be categorized into two categories:

Static - The heads of these tools do not contain a swivel for rotation.

Rotary - These heads contain a swivel and rotate under the power of the water jets.

Tool selection

When selecting a tool, the first step is to determine what size tool will best fit into the pipe being cleaned, and whether the pipe is straight or has elbows. Next is selecting a tool capable of handing the pressure and flow rate required for effective cleaning.

Tool setup

Once the tool is selected, the jet placement (orientation) in the head of the tool must be determined. The magnitude of the pulling force required to make the run and whether the pipe has scale or is partially or fully blocked will determine the location and number of jets in the cleaning head.

Finally, for rotary-type or forced rotation type tools, the rotation speed of the head, based on the size of the pipe and the nature of the deposit to be removed. Typically slower rotation speeds are required in larger pipes or if the deposit is very thick and hard to remove therefore requiring more jet dwell time.
