Aluminum Alloy Nuts, Chemical Nuts, and Precision Hardware Parts CNC Turning Services
We provide comprehensive CNC turning services for aluminum alloy nuts, chemical nuts, and precision hardware parts, leveraging advanced equipment and technology from Japan and Germany to deliver superior quality components.
Application and Characteristics of Aluminum Alloy Positioning Bushes in Chemical Equipment Hardware
Core Application Scenarios
Pumps and Valves (Most Widely Used)
Positioning of pump bodies and covers for centrifugal pumps, magnetic pumps and chemical pumps
Stem guiding bushes for globe valves, ball valves, butterfly valves and control valves
Sealing components: positioning support for stuffing boxes and mechanical seals
Reactors and Pressure Vessels
Stirring shaft positioning: guiding for stirring shafts in reactors and autoclaves
Manhole/quick-opening structures: positioning and sealing of flanges
Piping and Fluid Transportation Systems
Pipe supports and clamps: lightweight and corrosion-resistant positioning
Expansion joints: bushes provide guidance and positioning
Filtration and Separation Equipment
Centrifuges and filter presses: positioning bushes for drums, filter plates and spindles
Membrane separation and ion exchange: component positioning and sealing
Instruments and Actuators
Flow meters, level meters and control valves: positioning and guidance
Pneumatic/electric actuators: connecting rods and shaft bushes
