Tungsten Carbide Spiral Nozzle for PDC Bits in Cross Shape
These Tungsten carbide Nozzles are made from hot pressing with
straight bore and venturi bore type. Due to its hardness, low
density and excellent wear and anti-corrosion, Tungsten carbide
nozzle has been widely used in sandblasting and shot peening
equipment, offering a long life with optimum air and abrasive use.
Zhuzhou Zonco Sinotech Wear-resistant Material Co,. LTD. is a

business relationships with new customers.
Basic Information
The cemented carbide nozzles are mostly to be used for water
cooling and slurry scouring of the drill bit during the drilling.
The size and the form of the water holes should be designed
selectively according to the different geological conditions and
the flow rate. The nozzles are normally divided into two kinds
according to the varied drill bits and the conversion requirement,
one of these is with thread and another without thread. The nozzles
without thread are mainly to be used to the PDC drill bits.
Types
There are five kinds of the nozzles including cross type(4 slots),
Y type(3 slots), hexagonal type, internal hexagonal type and plum
blossom type according to the assembling and disassembling with
different tools(wrench).
All kinds of the thread including the metric norm, inch norm, and
USA norm(thick teeth, fine teeth, and special teeth) can be made,
and the accuracy of the thread reaches 3 A of the American
standard(the highest accuracy). The size of water jetting holes of
the nozzles that we now produce is from 0 to 17.5mm diameters. The
quality of the products takes an advanced level in China.
Our Advantages
There are many different sizes and types of the products for choose
and we can also provide to our customers with the products
according to their drawings and requirements.
Wide variety of nozzles, including threaded, standard, and
extended, for all bit designs. Precision manufactured for optimal
nozzle location and arrangement, improved flow velocity, and
reduced pressure loss.

Cemented Carbide Nozzle
Application:
The cemented carbide nozzles are used to PDC drill bits and cone
roller bits for flushing, cooling and lubrication drill bit tips
and cleaning stone chips in the well bottom with drilling liquid in
the working conditions at high pressure, vibration, sand and slurry
impacting during oil and natural gas prospecting process.
