Tungsten Carbide Nozzle Types

Tungsten carbide nozzle is a kind of device that composed of the hard phase WC and the binder phase Co, and through a closed cavity or conduit, and out of controlled substances or special direction of gas flow and accelerate. Its hardness can reach 90HRA, tensile strength can reach 2300N/mm and it has the highest competitive price among the nozzle materials due to its good performance in wear and corrosion resistance. At present, tungsten carbide nozzle has been widely used in blasting and shot peening equipment, which can effectively ensure the related products can be used in best atmosphere and abrasives for a long time.

Tungsten carbide nozzle has many types, according to the shape of the nozzle hole (airflow pattern), it can be divided into straight hole, mound hole and restricted hole. The common straight hole has internal air flow in a stream, live or work to form a sealed-type airflow pattern, is often used in some of the more simple, small cleaning work, such as cleaning and welding molded parts, cleaning the house, handrails, stairs, stone carving and so on. Besides, tungsten carbide straight hole nozzle also includes hollow cone nozzles, solid cone nozzles, nozzle square, rectangular nozzles, oval nozzle, fan nozzle, column flow (DC) nozzles, two-fluid nozzle, multi-fluid nozzle and so on. Mounted nozzle can form a relative full flow mode for a given polishing rate of pressure increase up to 100%, compared to the long mound-like nozzle straight bore nozzle in the case of 40% less abrasive consumption may increase 40% in productivity. Venturi nozzle is the best choice for large airflow surface to improve the efficiency. Nozzle with wide throat is also called as wide-angle nozzle, which can be specifically divided into large droplets and small droplets nozzle. It has a large export and a big difference out of the hole when the hose matches the same size, its productivity can be improved by nearly 15% smaller than conventional nozzle throat. In addition, according to different classification methods, tungsten carbide nozzle also has many types, such as petrochemical nozzles, nozzle agriculture, textile nozzle, paper nozzles, nozzle printing, environmental protection (desulfurization, denitrification, denitrification, dust, etc.) nozzle, spray nozzle, steel nozzle metallurgy, electronics nozzles and so on by the applications.
