Product Description

Tungsten carbide nozzles are installed on roller bits and PDC bits. When working, the nozzle sprays drilling fluid to cool the drill bit, flush the mud, and assist in rock breaking. There are mainly two types of threaded nozzles and non-threaded nozzles.

Advantages Of Tungsten Carbide Nozzles

Strong plasticity: Take our factory as an example. We are a custom factory that manufactures according to drawings. As long as you have a drawing, we can press the corresponding geometric shape through our own blank production line and then perform fine grinding. This is one of the benefits brought by mold processing. Even if you don’t have an exact drawing, but as long as you can provide sufficient information, such as approximate dimensions, working environment and other data, we also have a way to start from scratch.
Excellent physical and chemical properties: Tungsten carbide parts are made by pressing and sintering corresponding metal powders in a certain proportion and then grinding. This manufacturing process endows the nozzles made of hard alloy with a special pore structure, which can maintain its own hardness even in harsh usage environments such as oil and gas extraction, without cracking or wearing out to lose its original precision.

Applications Of Tungsten Carbide Nozzles

Oil and gas extraction

In this industry, hard alloy nozzles are mainly used in high-pressure cleaning, sand control treatment, drilling fluid jetting, etc. During extraction and equipment maintenance, the nozzle part needs to come into contact with drilling fluid and other high-pressure and high-speed fluids. Due to long-term and repeated strong erosion, if steel or ceramic nozzles are used, their replacement rate will be very high.

Chemical and metallurgical industries

In the chemical and metallurgical industries, corrosive media are common. Workers use special devices like nozzles to achieve purposes such as cleaning and atomization for process manufacturing. Corrosive substances like caustic soda, synthetic gas, and high-temperature molten metals repeatedly erode the nozzle area.

Precision mechanical processing

In precision machining, the application of nozzles involves functions such as coolant supply, chip removal, and lubrication. Besides the basic requirements of high-temperature resistance, high-pressure resistance, and wear resistance for the nozzle material, the precision of mechanical processing also sets higher standards for the precision of the nozzles themselves.
