How To Properly Size Your Blast Hose

SIMPLE WAY TO DETERMINE IF YOU’RE BLAST HOSE IS THE CORRECT SIZE

If you’re familiar with our Primed Insights – or BlastOne consulting in general – you’ll know we are huge proponents of blasting with a minimum of 100psi at the nozzle! Visiting jobsites, it’s normal to find actual pressures much lower. Recently we visited a ship yard that had 8 operators working at 35psi! They simply didn’t know.

Part of the issues was they were using the wrong sized whip hoses. They were too small for the nozzles being used.

SIMPLE RULE OF THUMB FOR SIZING BLAST HOSE

• Blast hose = 3x Nozzle size (internal diameters)
• Blast hose = 4x Nozzle size (internal diameters)

Here’s a very useful chart taken from our catalog giving standard sizing for various nozzles and hose based on pressure.

You can easily test your pressure by using a BlastOne Nozzle Pressure Test Kit. Anything below 100 PSI coming out of the nozzle is going to cost you profits.
