Media That Can Be Used In Flange Ball Valves
It can be used for water, oil, steam, natural gas, nitrogen, etc. For the main pipelines of oil and natural gas transportation, pipelines that need to be cleaned, and pipelines that need to be buried underground, choose ball valves with full diameter and full welded structure; for those buried on the ground, choose Ball Valve with full diameter welding connection or flange connection; for branch pipes, choose flange connection, welding connection, full diameter or reduced diameter ball valves.
For the transportation pipelines and storage equipment of refined oil, choose ball valves with flange connection.
For the pipelines of city gas and natural gas, choose floating ball valves with flange connection and internal thread connection.
In the oxygen pipeline system of the metallurgical system, it is advisable to use fixed ball valves with strict degreasing treatment and flange connection.
For the pipeline system and equipment of low-temperature media, it is advisable to use low-temperature ball valves with valve covers.
For the pipeline system of the catalytic cracking equipment of the refining equipment, a lifting rod ball valve can be selected.
In the equipment and piping systems of chemical systems with corrosive media such as acids and alkalis, it is advisable to use all-stainless steel ball valves made of austenitic stainless steel and polytetrafluoroethylene as valve seat seals.
Metal-to-metal sealing ball valves can be used in the piping systems or equipment of high-temperature media in metallurgical systems, power systems, petrochemical equipment, and urban heating systems.
When flow regulation is required, a worm gear-driven, pneumatic or electric regulating ball valve with a V-shaped opening can be used.
