Because steam and oil and gas media may have high temperatures and corrosiveness, special attention must be paid to the selection of sealing materials. Make sure that the selected sealing material can withstand the working pressure, temperature and possible corrosive effects of the medium. For high-temperature steam, it is necessary to select a sealing material that is resistant to high temperatures; for oil and gas media, it is necessary to consider the material's oil resistance and corrosion resistance.
Although the valve body material of this check valve is available in carbon steel and stainless steel, the adaptability of the material still needs to be carefully evaluated when used for steam and oil and gas media. Stainless steel materials generally have better corrosion resistance and high temperature resistance and may be more suitable for these media. However, the specific selection still needs to be determined according to the characteristics and working pressure of the medium.
Make sure that the installation direction of the check valve is consistent with the flow direction of the medium to prevent the medium from flowing back. For large check valves, independent support should be used to reduce the impact of the pressure generated by the pipeline system. Regularly check the sealing performance of the check valve and the wear of the valve core and valve seat to ensure that the valve can function normally and safely. Keep the inside of the check valve clean and free of foreign matter and corrosive substances. For valves used for a long time, regular maintenance and care should be performed.
When used for oil and gas media, the explosion-proof performance of the check valve should be considered to ensure that the valve can be safely closed in the event of medium leakage or abnormal conditions. For high-pressure steam and oil and gas media, the check valve should have sufficient pressure release capacity to prevent the valve from being damaged or leaking due to excessive medium pressure.
When installing and using check valves, relevant standards and specifications should be strictly followed, such as national standards, industry standards, or installation guides and operating instructions provided by manufacturers. These standards and specifications usually contain detailed requirements and recommendations on valve selection, installation, maintenance, and inspection.
