What is the typical pressure used for high-pressure water blasts when cleaning vessels?

In high-pressure water blasting applications for cleaning pressure vessels, the typical pressure range utilized is between 8,000 to 20,000 PSIG. This range provides sufficient force to effectively remove contaminants, deposits, and buildup inside the vessels without damaging the vessel material itself. High-pressure water blasting is a common practice in the maintenance of pressure vessels in various industries, including manufacturing and petrochemicals, due to its efficiency and effectiveness.

Within this range, the pressure must be carefully controlled. Pressures below this threshold may not adequately clean surfaces, while pressures exceeding this range can increase the risk of damaging the vessel or leading to safety hazards. Understanding the appropriate pressure limits is crucial for anyone involved in the inspection and maintenance of pressure vessels to ensure both operational effectiveness and safety.
