Key features

Aerodynamically optimized spiral scroll geometry minimizes gas turbulence and maximizes kinetic-to-static pressure conversion.

Cast from high-density nodular iron with superior fatigue strength to resist continuous thermal stress and pressure pulsation.

Ultra-dense casting microstructure guarantees zero micro-porosity gas leakage under high operating discharge pressures.

High-rigidity frame design maintains strict internal clearances between the impeller, diffuser, and scroll under heavy loads.

Product Q&A

Q:Why is Ductile Iron preferred over Gray Iron for centrifugal air compressor scroll casings?

Centrifugal compressors operate under continuous pressure pulsations, thermal stress, and high gas velocities. Ductile Iron (ASTM A536) provides twice the fatigue limit of Gray Iron, preventing casing fractures and ensuring dimensional stability over long operation cycles.

Q:Can your scroll casing match our existing diffuser ring and impeller clearances?

Yes. We machine internal scroll profiles, diffuser seating faces, and mating flanges on high-precision CNC boring centers. We hold critical axial and radial tolerances to within microns based on your engineering drawings.

Q:Do you provide material certificates and quality documentation?

Yes, every shipment includes an EN 10204 3.1 Material Test Certificate (MTC) detailing chemical composition, tensile strength, yield strength, hardness, and non-destructive testing (NDT) reports upon request.
