What is the typical pressure range used for high pressure water blasting when cleaning vessels?

The pressure range of 8000-12,000 PSIG is commonly employed in high-pressure water blasting, particularly for cleaning pressure vessels. This range is effective in removing tough deposits, such as rust, scale, and other contaminants found internally within a vessel. High pressure is necessary to ensure that the water can penetrate deeply into the surfaces and provide thorough cleaning.

In industrial settings, this level of pressure is typically utilized for applications where extensive cleaning is paramount to maintain safety and efficiency. This range strikes a balance between delivering enough force to dislodge stubborn materials while managing the safety risks associated with very high-pressure cleaning, such as equipment damage or safety hazards to workers.

Other specified pressure ranges, while still useful in different applications or for lighter cleaning tasks, do not achieve the necessary force for the most challenging cleaning scenarios that vessels often encounter. Consequently, using the 8000-12,000 PSIG range is standard practice for effective and safe cleaning operations.
