Tungsten Carbide Venturi Nozzle Introduction

Details: Category: Tungsten Information; Published on Friday, 17 October 2014 17:49; Written by xjq; Hits: 460

Tungsten carbide Venturi nozzle is a kind of widely used tungsten carbide product, with excellent properties of high hardness, abrasion, corrosion resistance, etc.

The structure of tungsten carbide Venturi nozzle can be divided into three parts, namely,convergent section, straight section and diffusion section. Tungsten carbide venturi nozzle more than doubles the abradant outlet velocity than straight hole nozzle under the same pressure. It works more efficiently with higher hardness, abrasion resistance and longer service life.

Tungsten Carbide Sand Blasting Nozzle

Details: Category: Tungsten Information; Published on Friday, 17 October 2014 17:46; Written by xjq; Hits: 501

Tungsten carbide sand blasting nozzle, characterized by its high hardness, abrasion and corrosion resistance, is an important part of sand-blasting guns. It is highly durable and suitable to be employed in working environments where rough working and brittle nozzle damage may easily happen. In addition, the Venturi design and air supply of this kind of nozzle can ensure its high efficiency.

Tungsten carbide sand blasting nozzle has wide application scope, which includes the paint process in industries like petroleum drilling, airplane, ship, car,bridge, etc. and jean surface treatment.Sand blasting and rust cleaning products produced by tungsten carbide injection molding technology are mainly applied in sand blasting and rust cleaning treatments of large scale equipment in areas like ship, bridge, chemical engineering, container, water conservancy, machinery, pipeline,etc. and their components and parts.

Tungsten Carbide Self-excited Pulsed Nozzle Introduction

Details: Category: Tungsten Information; Published on Friday, 17 October 2014 08:47; Written by xjq; Hits: 452

Tungsten carbide self-excited pulsed nozzle is developed and manufactured according to the principle of self-excited oscillation and can be used as the nozzle of roller bit. It addition to possessing the excellent properties of common tungsten carbide nozzles, it also has its unique property of intermittent jet, which improves operation efficiency.

The principle of tungsten carbide self-excited pulsed nozzle is as follows: The water jet flow coming out from the upper part of the nozzle is reflected by the upper and lower surfaces. The reflection pressure wave in the upper surface equals to the initial phase of water pressure wave moving downwards and thus forming wave superposition, which hit the jet flow reflected by the lower surface, resulting in strong circular shear stress, which makes high shear jet stream into instantaneous vacuum form alternating water bomb. High pressure generated in the vacuum projects the water bomb at a high speed, forming discontinuous water bomb jet flow, and thus overcoming the disadvantages of low energies of continuous jet nozzles and improve the instantaneous impact force of the jet effective spray distance and the hydraulic energy when the jet flow arrives at the cleaning area.

Manufacturing Technique of Tungsten Golden Bar

Details: Category: Tungsten Information; Published on Friday, 17 October 2014 09:00; Written by Sherry; Hits: 466

Golden tungsten bar is manufactured in the form of bar, which is rectangle. Tungsten alloy is first made before plating gold on it. The tungsten alloy bar also has the properties of tungsten-high density and corrosion resistance. Therefore, the value would be remained as gold for the increasing value of tungsten and gold in August, 2011.

After the manufacturing of tungsten alloy bar, engraving should go next. After the choosing of letters, our technician would think of the difficulties of engraving, and work out methods of appropriate proportion to engrave. We always engrave words as customer' s drawings.

When engraved, the tungsten bar can be chamberred, for that people are not to get hurt form the sharpe edges. However, the unchambered tungsten golden bar also has the pleasant suface.The last procedure of manufacturing tungsten golden bar is to plate gold of 18K or 24K on it. This is also a choice made by customers.

Tungsten Carbide Drill Nozzle Introduction

Details: Category: Tungsten Information; Published on Friday, 17 October 2014 08:40; Written by xjq; Hits: 471

Polycrystalline diamond compact bit, referred to PDC bit, is a kind of drilling tool commonly used in geological drilling industry. When working in soft to medium hard formations, PDC bit has many advantages like high speed, deeper drilling depth, long service life, stable working condition, few drilling troubles, high well quality and so on.PDC bit’s high performance should give credit to the tungsten carbide drill nozzle.

Tungsten carbide drill nozzle is a kind of directional nozzle with one or more lateral pores. When installed on PDC bit, it can be used to cleaning drills and wells. Common tungsten carbide drill nozzle is cylindrical and can spread balanced pressure on rock surface.

During the drilling process, tungsten carbide drill nozzle can restrain bit balling development and improve drilling speed and assure drilling safety.
