2. Product Definition
Titanium tube sleeve is short‑length precision tubular component processed from seamless titanium tube, used as bushing, ferrule, connecting sleeve and protective sleeve.
-
By material grade: Grade2 pure titanium sleeve, Grade5 Ti‑6Al‑4V alloy sleeve
-
By structure form: Straight‑through sleeve, step‑bore sleeve (custom available)
3. Material Advantage: Material‑Medium‑Corrosion‑Cleanliness
-
Grade2 (CP‑Ti): Excellent corrosion resistance for seawater, salt spray, neutral chloride medium. Low hardness, good ductility, easy machining. Clean surface free of heavy‑metal residue, suitable for non‑load‑bearing corrosion‑resistant assembly.
-
Grade5 (Ti‑6Al‑4V): High strength and wear‑resistant property. Resists marine salt spray and weak acid medium. For high‑load structural sleeve parts. Not fit for strong reducing acid environment without palladium alloy addition.
-
Surface cleanliness: Deburred, degreased and cleaned after CNC machining; no cutting‑fluid residue for assembly requirement.
4. Technical Standards
-
Base tube standard: ASTM B338 seamless titanium tube
-
Machining drawing standard: ISO general dimensional tolerance specification
-
Reference: ASTM B265 for raw material verification
-
Certificate: EN10204 3.1 MTC for raw tube; dimension inspection report for finished sleeves, batch traceability.
5. Full Manufacturing Workflow: From Drawing To Finished Goods
-
Raw material incoming inspection: Check seamless titanium tube dimension, material certificate, surface quality.
-
Tube cutting: Precise length cutting with low‑stress sawing.
-
CNC turning: Machine outer diameter, inner diameter, wall thickness to reach ±0.02‑0.05mm tolerance.
-
Deburr inner & outer edges, remove sharp corners.
-
Surface treatment: Polishing / brushing / anodizing as customer requirement.
-
Ultrasonic degreasing & cleaning to remove machining oil residue.
-
Full dimension sampling inspection, visual surface check.
-
Labeling, dust‑proof packaging for export shipment.
6. Key Component Performance
-
Machining accuracy: Strict OD / ID / wall‑thickness tolerance control; key dimension 100% sampling inspection.
-
Weldability: Grade2 has good weldability; Grade5 needs argon shield protection during welding operation.
-
Non‑destructive test: Raw tube UT inspection for internal defects; visual check for surface scratch and crack.
-
Surface performance: Anodized layer improves wear resistance and anti‑scratch property.
