High-pressure pipeline systems are widely used in multiple industrial fields such as petroleum, natural gas, chemical engineering, and power. Their operating conditions typically involve high pressure, high flow rate, and complex medium environments. Ball valveshave been widely used in high-pressure pipeline systems due to their compact structure, convenient operation and good sealing performance. However, due to the particularity of high-pressure pipeline systems, the selection of ball valves needs to be more cautious to ensure their reliability and safety under complex working conditions.
Medium Type: Select corrosion-resistant materials such as stainless steel or alloy steel according to the chemical properties of the medium.
Medium Temperature: High-temperature media require the selection of high-temperature resistant materials, while low-temperature media require the selection of low temperature steel.
Medium Pressure: The pressure rating of the ball valve should be higher than the maximum working pressure of the pipeline.
Valve Body Material: High-strength carbon steel, low-alloy steel, or stainless steel are common choices.
Sealing Material: Under high-temperature and high-pressure conditions, metal sealing surfaces are superior to soft sealing materials.
Surface Treatment: Micro-arc oxidation or laser cladding can improve the wear resistance and corrosion resistance of components.
Floating ball valves and trunnion ball valves: Floating ball valves are suitable for small and medium-sized diameters, while trunnion ball valves are suitable for large diameter and high-pressure working conditions.
fully welded ball valves: The fully welded structure has good sealing and corrosion resistance.
Connection methods: Flange connection, welding connection, and threaded connection each have their advantages and disadvantages, and need to be selected according to the working conditions.
