Built for Tough Alloys: High‑Strength Tube Straightening Machine

Engineered to correct bends and twists in stainless steel, titanium, Inconel, and high‑strength alloy tubes – delivering ≤0.2 mm/m straightness without surface damage or work hardening.

The Challenge of Straightening High‑Strength Alloy Tubes

Tubes made from tough alloys – such as 17‑4 PH stainless, Ti‑6Al‑4V titanium, Inconel 718, and high‑strength carbon steels – resist permanent deformation. Their high yield strength and spring‑back make conventional straighteners ineffective. Worse, improper straightening can induce cracking, work hardening, or surface galling.

Our Solution: A Straightener Built for Tough Alloys

FangRong’s high‑strength tube straightening machine combines robust construction with intelligent control to master difficult materials:

• Heavy‑duty multi‑roll or rotary design – Withstands the high forces required for alloy straightening.

• CNC servo‑controlled roll pressure – Applies precisely calculated over‑correction to compensate for spring‑back.

• Closed‑loop laser measurement – Verifies straightness in real time and auto‑adjusts roll positions for consistent ≤0.2 mm/m results.

• Surface‑protective roll coatings – Polished carbide or polyurethane rolls prevent galling on titanium and stainless.

Key Features for Tough Alloys

Feature	Benefit
High‑tonnage hydraulic roll adjustment	Up to 100+ tons of straightening force
Variable speed control	Slow, controlled passes for work‑hardening‑sensitive alloys
Twist correction station	Eliminates axial rotation common in cold‑drawn alloy tubes
Data logging	Full traceability of straightness values for AS9100 / ISO audits

Typical Results

Alloy	Tube Size	Incoming	Outgoing Straightness
17‑4 PH stainless	25×2 mm	4.5 mm/m	≤0.12 mm/m
Ti‑6Al‑4V titanium	15×1.5 mm	3.8 mm/m	≤0.10 mm/m
Inconel 718	20×2.5 mm	5.0 mm/m	≤0.15 mm/m
4140 steel (heat treated)	30×3 mm	3.5 mm/m	≤0.10 mm/m

Applications

• Aerospace – Hydraulic lines, fuel system tubing, actuator components

• Oil & gas – Downhole instrumentation, control lines, valve components

• Medical – Surgical instrument tubes, implantable device cannulas

• Power generation – Heat exchanger tubes in aggressive environments

Why Standard Straighteners Fail on Tough Alloys

• Insufficient force – Cannot overcome high yield strength.

• No spring‑back compensation – Alloy springs back after passing through rolls.

• Surface damage – Hard alloys gall against uncoated steel rolls.

• Residual twist – General‑purpose straighteners lack dedicated twist correction.

FangRong’s Advantage

• 20+ years of experience with difficult‑to‑straighten alloys.

• Custom roll contouring for thin‑wall or heavy‑wall tubes.

• Pre‑shipment testing with your alloy samples.

• Global service support.

Conclusion

For manufacturers processing high‑strength alloy tubes, ordinary straighteners are not enough. FangRong’s high‑strength tube straightening machine delivers the force, precision, and surface protection required to achieve ≤0.2 mm/m straightness – consistently, without compromising material integrity.
