Zirconium Seamless Tubes

Zirconium Seamless Tubes

XI AN LINHUI IMPORT AND EXPORT Co., LTD. manufactures Zirconium Seamless Tubes to ASTM B658 and GB/T 26283 standards, featuring grades ZR60702 and ZR60705. Produced through advanced hot extrusion and cold pilgering across two factories with 30 production lines, our tubes eliminate welded seams and heat-affected zones—critical weak points in corrosive chemical and nuclear applications.

With 21 a long time of titanium and zirconium metal fabricating encounter, we convey tubes accomplishing thickness resistance inside ±0.05mm, 100% NDT review, and full traceability per EN 10204 3.1/3.2. Our consistent development guarantees predominant burst quality and erosion insusceptibility in situations where stainless steel falls flat inside months—particularly in high-temperature natural acids and decreasing atmospheres.

Key Features & Benefits

Exceptional Erosion Resistance

Self-healing ZrO₂ oxide layer withstands sulfuric corrosive (<70%), acetic acid, and hydrochloric environments where titanium degrades rapidly.

Zero Weld Seams

Seamless construction eliminates localized corrosion points and premature failure risks common in welded alternatives.

Nuclear-Grade Performance

Low thermal neutron absorption cross-section prevents structural embrittlement in reactor applications under 150 atm pressure and 350°C.

Dimensional Precision

Controlled cold pilgering maintains tolerance within ±0.05mm for reliable assembly in heat exchangers and process vessels.​​​​​​​

Why Choose Us?

Coordinate Plant Access

Eliminate go betweens markup—our vertically coordinates generation guarantees competitive estimating and quality control from ingot to wrapped up tube.

Rapid Response

4-hour citation turnaround, 24-hour drawing survey, and stock conveyance inside 3–7 days for pressing extend requirements.

Full Traceability

Every tube incorporates warm number following with total MTC documentation per EN 10204 3.1/3.2 standards.

Engineering Support

In-house metallurgists help with fabric determination, erosion investigation, and application-specific proposals for your handle conditions.

Manufacturing Process

Step 1: Vacuum Circular segment Melting

High-purity zirconium ingots experience rehashed softening cycles to evacuate hafnium and follow debasements, guaranteeing steady chemistry.

Step 2: Hot Extrusion

Billets are warmed to 750–850°C and expelled through exactness passes on, shaping the starting empty tube structure.

Step 3: Cold Pilgering

Multiple lessening passes accomplish last measurements and upgrade mechanical properties whereas keeping up strict resistance control.

Step 4: Strengthening & Finishing

Vacuum strengthening diminishes leftover stretch. Tubes get salted, cleaned, or sandblasted wraps up per client specifications.

Applications

Chemical Processing

Heat exchangers, reboilers, and condensers in acidic corrosive, urea, and melamine plants where forceful media assault standard alloys.

Nuclear Energy

Fuel cladding tubes in PWRs and BWRs, containing uranium pellets beneath tall radiation whereas standing up to light creep.

Acid Regeneration

Sulfuric corrosive recovery frameworks working at changing concentrations and bubbling temperatures without inactive layer breakdown.

Pharmaceutical Manufacturing

Process channeling dealing with destructive intermediates requiring outright fabric virtue and contamination-free surfaces.

Export Markets

Our Zirconium Seamless Tubes reach 60+ countries across North America (USA, Canada), Europe (Germany, France), Middle East (UAE, Saudi Arabia), and Asia-Pacific (Japan, South Korea). We maintain long-term partnerships with EPC contractors like CEFC, PTT, PETRONAS, and LUKOIL in refinery and chemical plant projects.

FAQ

Q: Can these tubes be welded to stainless steel?

A: Direct welding creates brittle Zr-Fe intermetallics. Use mechanical flanges or explosion-bonded transitions instead.

Q: What's the difference between ZR60702 and ZR60705?

A: ZR60705 contains 2–3% Niobium for enhanced strength and corrosion resistance in severe chloride environments.

Q: How do you prevent hydrogen embrittlement?

A: Controlled pilgering creates circumferential hydride platelets rather than radial ones, mitigating crack propagation risk.

Q: Why the higher cost versus titanium?

A: Complex Hafnium separation, vacuum arc melting, and low-yield seamless extrusion drive premium pricing—but lifespan is decades versus months in reducing acids.

Q: Maximum continuous operating temperature?

A: 350°C practical limit for chemical service; above this, oxide layer thickening accelerates and becomes brittle.

Q: Minimum order quantity for custom sizes?

A: 100 kg from stock; custom runs typically require 500 kg but we accommodate trial orders after technical consultation.
