Petroleum is the "blood of industry", and a scientific and effective oil extraction process is an inevitable requirement for social and economic development. In the process of oil extraction and transportation, parts such as flow bushings, plug rings, wear-resistant sleeves, oil pump valve balls, valve seats, and valve sleeves need to be used in combination. The high hardness, high density, high strength and stable chemical properties of tungsten steel materials as well as its good bending strength and impact toughness make the performance of tungsten carbide products in improving oil drilling and transportation surpass other material options, excellent wear resistance Loss of corrosion resistance greatly improves drilling efficiency, extends tool life, and reduces operating costs.In order to meet the customized processing of tungsten carbide to meet the requirements of more petroleum machinery equipment accessories, our company provides multiple choices of tungsten carbide processed tungsten steel materials. The commonly used physical parameters of tungsten carbide processed tungsten steel materials are as follows:
1. Grain size um: 0.4～2.0
2. Cobalt content Co%: 6.0-20
3. Density g/cm3: 13.96-14.85
4. Hardness HRA: 89.5-93
5. Bending strength MPa: 3200-4500
6. Young’s modulus Gpa: 570-620
The demand for high-performance mechanical parts in modern manufacturing industries has become an important dependence on improving production efficiency and promoting economic development. For the petroleum industry, high-quality products in the equipment manufacturing industry are basic equipment that ensures safe operation and long-term use of petroleum production lines. The performance requirements for bushings, bushings, and ring products have become an inevitable focus, which reflects the importance of tungsten carbide tool products. Promotional work in the petroleum industry, aerospace, and automobile industries. The corrosion resistance, high temperature resistance and wear resistance of tungsten steel bushings and tungsten steel shaft sleeves are the basic requirements for long-term operation of petroleum machinery. In particular, the production and processing of precision petroleum machinery tungsten carbide bushings and tungsten steel flow bushings that require relatively high dimensional accuracy require quite rigorous process cooperation.
