The bypass valve required for the use of petroleum liquid machinery is also called a self-operated bypass differential pressure valve. It is a valve installed on a bypass pipe, such as a pressure reducing valve, a control valve and a steam trap, etc., which are usually installed with a bypass pipe. to the bypass valve. As a supplement to the performance of the pressure reducing valve and steam trap, the bypass pipe is used to provide more pressure or flow, requiring the valve to have lower resistance, so the valve is often in a fully open state during use. If a control valve is installed in the pipeline and the valve is required to be opened/closed quickly, the tungsten steel sleeve of the bypass valve made of tungsten steel can better meet the performance requirements.
Tungsten steel valve sleeves are used for precision production of tungsten steel valve cores for bypass valves. Tungsten steel valve sleeves are widely used in the oil drilling industry because of their good physical properties. The working environment of the oil drilling industry is harsh. Usually, sand-bearing wells, heavy oil wells, and high-pressure oil-repellent wells contain some highly corrosive substances such as water, various gases, wax, and sand. Even thousands of meters of strata are extracted, which requires valve sleeves, valve balls and valve seats to have good sealing performance, wear resistance and corrosion resistance. In some deep oil wells with high water content, no gas and oil wells with strong corrosion and large sand content, tungsten steel valve core and tungsten steel valve sleeve can better reflect the characteristics of high density, wear resistance and corrosion resistance. Excellent performance.
Our company provides multiple options for processing tungsten steel materials. The physical parameters of commonly used tungsten steel valve sleeve materials are as follows:
1. Grain size um: 0.4～2.0
2. Cobalt content Co%: 6-20
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
