Project Description
FLAT FAN NOZZLE
HIGH IMPACT NOZZLES – SPECIAL SIZE
High Impact nozzles are widely used in hot rolling processes as they provide an adequate impact for a consistent descaling. The modern design of these nozzles offers the convenience of a more rational alignment system which allows a copper seal to be used between nipple and nozzle tip. The nozzle efficiency is enhaced by means of a carefully designed flow stabilizer, which minimizes turbulence due to sharp direction change at the inlet from the main manifold. Provision is also made for a filter to be mounted at the nozzle inlet, minimizing nozzle clogging and abrasion.

ASSEMBLY PARTS
WELDING NIPPLES
ZWC
HV nozzles can be assembled on a series of different nipples, with the same inlet, but with three different lengths. The precision machined nipple inlet port assures precise positioning of the nozzle flat fan jet to the specific offset angle value of 15° with regard to the manifold center line.
FLOW STABILIZER
XHW
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. Different length nipples are available, with or without inlet filter. The codes always include a multifin flow straightener.
LOCKNUTS
VAW B100 B1
VAW D100 B1
The VAW B 100 B1 and VAW D 100 B1 locknuts for ZWB series descaling nipples have been designed profiting from a large experience on the field. The sturdy design and the generous dimensions give the maximum protection to the nozzle and the nipple thread. One lucknut size fits all standard size ZWB series nipple of any length.
GASKET
VDA 24C1 T3
The VDA 24C1 T3 round gasket provides proper assembly between nozzle and nipple. One size fits all standard size ZWB nipple types.
