Centrifugal Casting Steel Tube – For Large Spool Reels, Heat-Treated, Alloy Steel, Custom Dimensions Available

Our Centrifugal Casting Steel Tubes are engineered for high-strength, heavy-duty applications, such as large spool reels, winches, and rotating machinery. 

Using centrifugal casting technology, these tubes deliver:

·Uniform wall thickness for consistent strength
·High fatigue resistance under heavy loads
·Custom dimensions for specific spool or reel requirements

All tubes are heat-treated to enhance hardness, toughness, and wear resistance, ensuring long service life.

 Typical Steel Grades

·35CrMoV – standard for heavy-duty spool reel tubes
·42CrMo, 40CrNiMo – optional for specialty applications
·Custom alloy compositions available upon request

 Size Range

·Outer Diameter (OD): Ø200–665 mm (7.874–26.18 in)
·Wall Thickness (WT): 10–100 mm (0.394–3.937 in)
·Length: Custom-cut up to 6 m (19.7 ft)

Common Sizes for Spool Reel Tubes (OD × ID × WT)

Wall thickness is calculated as (OD – ID)/2, rounded to typical manufacturing standards. Custom sizes are available on request.

Tolerances (per ASTM A297)

·OD: ±0.5 mm for Ø200–665 mm
·WT: ±10%
·Length: ±10 mm for cut lengths

 Manufacturing Process

1. Alloy Steel Selection – 35CrMoV or alternative grades
2. Centrifugal Casting – ensures uniform wall thickness and dense microstructure
3. Heat Treatment – normalizing, quenching, and tempering for hardness and toughness
4. Optional Machining – final OD/ID precision, end finishes, and drilling
5. Inspection – wall thickness, straightness, roundness, and surface quality
6. Ready for Assembly – tubes delivered to customer specifications
