Spray nozzles are available in many different materials of construction. Brass, cast iron, stainless steel, PVDF, CPVC – even titanium.
Which is right for your application? That depends on variables such as temperature, corrosion, abrasion, and chemical compatibility. Combining some of these variables, such as temperature plus abrasion, can decrease the expected performance or life span of a nozzle.
Here are some useful guidelines:
- Match the nozzle to the rest of the system. If the rest of the tank and piping is polypropylene, use a polypropylene nozzle.
- Some industry standards do exist. All food related applications will require either 316ss or PVDF to keep FDA inspectors happy.
- Chemical compatibility should be considered. For example, the printed circuit board industry prefers PVDF to handle the corrosive etching liquid.
- Most industrial applications choose 303 stainless steel to handle more aggressive pressures.
- Paint line washers tend to use polypropylene nozzles that offer high corrosion resistance and a lower cost.
