QUICK TIPS Calculate the recommended minimum spray ball flow rate required for cleaning process vessels by entering the tank diameter:
_______________ = _______________ x 9.5 (Spray Ball Flow in gpm) (Tank Diameter in feet)
A minimum flow rate of 3 gallons per minute (gpm) for every foot of tank circumference is required to produce sufficient turbulent flow to cascade solution down vessel walls.
Choosing a Spray Ball Type: Spherical: Most common spray ball; ideal for general patterns.
Tangential: The 90 degree / perpendicular flat area at the “top” of a tangential spray ball, allows for a vertical spray pattern. This can help provide maximum spray coverage to the top of a tank. Spray Bubble: These are size-on-size sprays (hemisphere to supply tube) and ideal for saving space. Although it is a space saving design, it’s important to recognize that the design also eliminates any “upward” spray coverage, assuming a vertical supply tube application. It’s essentially one half of a spray ball (one hemisphere), attached to end of tube with the same diameter.

Strainer Sizing: Use the below recommendations for sizing a strainer to use upstream of static spray balls. This will keep debris from being collected inside the spray ball which would reduce effectiveness of cleaning. Wedgewire Element: 0.015" or smaller
Mesh Overlay: 40 mesh or higher Filter Tubes: 425 micron or smaller
GOOD TO KNOW • Spray Ball Material: 316Lss • Maximum Operating Pressure: 70 psi • Wraparound clips are standard • Material Test Reports (MTRs) are available
• Hastelloy and AL-6XN material options are available for some spray balls • Custom spray balls require longer lead times
