Wear Resistance Tungsten Carbide Nozzle for PDC Bits
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
factory which is focused on precision of wear resistant components
and newmaterials research and production, marketing, meanwhile, we
offer cost effective products and material option solution for
those customers who seek high performance products used in extreme
complex working condition.Main products: hard alloy wear-resistant
parts, metal matrix composite wear-resistant parts, superhard
powder materials, etc.Our company has a strong ability of
transforming scientific research to actual production.
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.
