A thin-walled seamless stainless steel tube is a precision-manufactured hollow stainless component with a very small wall thickness relative to its diameter. The seamless process removes weld seams, ensuring uniform properties, improved reliability, and excellent performance in high-precision applications such as electric motor housings.
Outer Diameter (OD): approx. 1.0 mm up to 100 mm (varies by supplier)
Wall Thickness (WT): ultra-thin options from about 0.05 mm up to about 0.8 mm; regular thin-wall tubes may extend to several millimeters
Surface Finish: bright annealed, polished, or smooth cold-drawn finish
Manufacturing Process: cold-drawn or cold-rolled seamless tubing
Lightweight yet strong: Thin wall design reduces mass while maintaining structural integrity.
Corrosion & temperature resistance: Stainless alloys provide excellent resistance to oxidation, corrosion, and thermal exposure.
High dimensional precision: Seamless tubes offer tight tolerances, smooth internal/external surfaces, and excellent roundness.
Reliable structural performance: No weld seam eliminates seam-related weaknesses, improving fatigue and mechanical reliability.
Flexible customization: OD, WT, length, and finish can be tailored to suit different motor designs.
1. Weight Reduction
Customers often need lighter housings to improve motor efficiency and reduce inertia.
Advantage: We supply ultra-thin seamless tubes with extremely low wall thickness while preserving mechanical strength.
2. Reliability Under Vibration and Load
Motors experience continuous vibration and cyclic loads.
Advantage: Seamless construction provides superior uniformity and fatigue performance with no weld seam failures.
3. Corrosion and Environmental Durability
Motor housings in humid or chemically exposed environments require corrosion-resistant materials.
Advantage: We offer 304, 316L, duplex, and super-duplex grades with excellent corrosion resistance.
4. Precision for Tight Fits
Motor assemblies require accurate dimensions, smooth surfaces, and low friction.
Advantage: Cold-drawn production ensures high dimensional accuracy and excellent inner/outer surface quality.
5. Customization Flexibility
Different motors require different sizes and finishes.
Advantage: Wide range of OD/WT options and customizable finishes support diverse engineering needs.
