The design of the carbide nozzle is sintered according to the heat pressure of the hole and the hot straight hole. In the process of machining, precision grinding and surface treatment must be done to achieve the roughness of the hole roughness of Ra0.1 and r0.025. There is a scientific design of radius of curvature at two entrances.

Generally speaking,the shape of the design hole of the carbide nozzle is determined by the airflow pattern. Hard alloy nozzles generally have straight holes and perforations.

With the development of the oil industry and the increasing demand for energy, the technology related to oil drilling has been continuously promoted. Early oil drilling mainly USES human impact drill, mechanical cable drilling, rotary drill and so on, in the selected surface position of a certain diameter of the cylinder hole to the underground oil and gas layer. This type of high pressure air drill, drill hole drill and cone drill can be used with carbide ball tooth to improve the drilling efficiency and prolong the life of the drill bit. At present, the researchers have found a more effective high pressure abrasive jet technology for deep and marginal oil reservoirs. High pressure abrasive jet in high pressure water jet as the carrier, add a certain amount of abrasive particles, the impact of jet is greatly ascend,whichalso make the rock cutting efficiency is greatly improved, has a wider application prospect.

In the high pressure abrasive jet, a hard alloy nozzle is played. It has high hardness, high strength and excellent abrasion resistance. Usually in the process of drilling, usually in a high confining pressure conditions, thus the nozzle in the working process of the need to bear the high speed impact of high pressure abrasive, thus more prone to wear and failure. Ordinary materials, such as steel nozzles, are prone to heat deformation or disintegration, which require frequent replacement of nozzles, thus reducing the efficiency of drilling. In particular, it is very inconvenient to remove the drill bit when deep drilling is carried out. In addition, the inlaying of hard alloy materials in the most vulnerable parts of the nozzle is also a method to improve the performance of the nozzle and prolong its service life. The tungsten carbide nozzles can further improve the hardness of the nozzle and the abrasion resistance by reducing the size of WC grain size.

That is an introduction to the design of tungsten carbide nozzle, you can choose according to their industry and environmental characteristics required for hard alloy nozzle in combination with its working principle and design factors to select and efficient industrial applications.
