What pressure range is classified as high-pressure water cleaning?

The classification of high-pressure water cleaning falls specifically within the range of 5,000 to 10,000 psi. This method is effective for removing contaminants such as dirt, rust, and old coatings from surfaces, preparing them for new coatings or further surface treatments.

The rationale for this classification lies in the power and effectiveness of water jets within this pressure range, which can efficiently strip away unwanted materials without damaging the underlying substrate. Proper use of water pressure is crucial to achieve the desired cleaning results while minimizing surface impact, ensuring the integrity of the material being cleaned.

Other ranges do not fit the definition typically assigned to high-pressure cleaning. For example, pressures below 5,000 psi do not deliver enough force to convincingly clean heavy deposits or coatings and are considered more suited for lower-level cleaning tasks. Pressures exceeding 10,000 psi, especially those approaching or surpassing 30,000 psi, fall into ultra-high-pressure cleaning, which requires more specialized equipment and safety measures due to the increased risk of damage to surfaces and potential injury to operators.
