Project Description
FLAT FAN NOZZLE
HIGH IMPACT NOZZLES – MICRO SIZE
In some plants the centre-to-centre distance among descaling nozzles can be very narrow. In these cases the use of micro-descaling tips avoids the installation of nipples and nozzles or rings onto the spray manifold, which would be difficult, if not impossible, with standard nozzles.

ASSEMBLY PARTS
WELDING NIPPLES
ZWM 0035 B2
Micro descaling nozzles can be assembled on the ZWM 0035 B2 nipple, 35 mm. long. PNR can supply on request a series of different length. The precision machined nipple inlet port assures precise positioning of the nozzle flat fan jet to the specified offset angle value of 15 ° with regard to the manifold centre line.
FLOW STABILIZER
XHW MG20 T1
The flow stabilizer is a critical component for proper descaling, by reducing flow turbulence losses, a larger fraction of the water flow energy can be used for generating impact on the surface to be descaled. The design consists of a cylindrical brass body with a polished inner surface, housing a cast stainless steel flow stabilizer which straightens the liquid path to minimize turbulences.
LOCKNUTS
VAW MM18 B1
The sturdy design and the generous dimensions of this locknut give the maximum protection to the nozzle and the nipple thread.
GASKET
VDA 10A5 T3
The VDA 10A5 T3 round gasket provides proper assembly and secure seal between nozzle and nipple.
