Tantalum Seamless Tube
XI AN LINHUI IMPORT AND EXPORT Co., LTD. operates two specialized factories with 30 titanium metal production lines, bringing 21 years of manufacturing expertise in high-performance refractory metals. Our Tantalum Seamless Tube eliminates weld-zone vulnerabilities through precision extrusion and cold drawing processes, ensuring uniform grain structure across the entire cross-section.
With ISO/SGS/TUV certified quality control and an yearly generation capacity of 800 tons, we convey zero-defect tubing for forceful chemical situations. Our consistent development anticipates special erosion at weld beads—a basic advantage when dealing with hot concentrated HCl, H₂SO₄, and HNO₃ in shell-and-tube warm exchangers. Conveyance alternatives incorporate DHL, FedEx, discuss cargo, and ocean freight to meet your venture timelines.
Key Features & Benefits
Eliminates Disastrous Weld Failures
The consistent plan expels the weakest interface in destructive benefit. No weld dot implies no metallurgical heterogeneity where corrosive assault concentrates.
Superior Weight Integrity
Uniform divider thickness permits secure operation at higher weights. Perfect for U-bundle warm exchangers requiring tight bowing radii without basic compromise.
Extreme Chemical Resistance
Withstands concentrated sulfuric corrosive up to 175°C, all concentrations of hydrochloric corrosive underneath 100°C, and bubbling nitric acid—conditions where stainless steel and nickel amalgams come up short quickly.

Manufacturing Process
Step 1: Vacuum Bend Melting
High-purity tantalum powder experiences electron pillar dissolving in vacuum chambers to kill oxygen contamination.
Step 2: Rotating Forging
Ingots are hot-forged into empty billets. Temperature control guarantees grain refinement to ASTM 6 or better for ideal ductility.
Step 3: Cold Drawing
Multiple passes through exactness passes on decrease distance across whereas keeping up divider consistency. Middle of the road strengthening in vacuum avoids work hardening.
Step 4: Last Annealing
Tubes are stress-relieved at controlled temperatures to accomplish a completely recrystallized microstructure, basic for bowing applications.
Applications
Chemical Processing Heat Exchangers
Condenses and reboils concentrated acids in compact reactors. The Tantalum Seamless Tube enables U-bundle configurations without compromising structural integrity.
Semiconductor Manufacturing
Serves as thermocouple sheaths and CVD furnace components. High purity (3N5-4N grade) prevents silicon wafer contamination during high-temperature processing.
Nuclear Energy Systems
Contains liquid lithium and sodium loops in next-generation reactors. Tantalum's resistance to liquid metal corrosion ensures safety in fusion research applications.
Packaging & Shipping
Tubes are wrapped in polyethylene film, then packed in plywood crates with desiccant. Shock-absorbing foam protects tube ends during transit.
We offer DHL and FedEx for urgent samples, air freight for medium volumes, and sea freight for bulk orders. Full documentation includes EN 10204 3.1 certificates and customs paperwork.
Export Markets
Our product reaches 40+ countries including USA, Germany, Japan, South Korea, UAE, and Canada. We maintain partnerships with major EPC contractors like CEFC, PTT, PETRONAS, and LUKOIL.
Primary markets include chemical processing plants, semiconductor fabs, and research institutions requiring zero-failure performance in corrosive environments.
Quality Inspection
Ultrasonic Testing (UT) per ASTM E213 detects subsurface flaws.
Eddy Current Testing (ET) per ASTM E426 identifies surface discontinuities down to 0.1mm.
Hydrostatic Testing validates pressure capability at 1.5x design pressure. Dimensional verification uses laser micrometers to confirm ±0.05mm wall tolerance.
Metallurgical Analysis includes grain size evaluation (ASTM E112) and interstitial gas measurement to prevent embrittlement. 100% traceability via heat number documentation.
FAQ
Q: Can your item handle hydrofluoric acid?
No. HF and fluorine gas quickly assault tantalum by stripping its defensive oxide layer. Soluble arrangements and oleum moreover cause serious corrosion.
Q: What's the advantage of Ta-2.5W over unadulterated tantalum?
Ta-2.5W (R05252) offers 30-50% higher pliable quality whereas keeping up erosion resistance. It's favored for high-pressure or high-velocity applications.
Q: Can tantalum work in discuss at tall temperatures?
Above 300°C, tantalum responds with oxygen and nitrogen, causing embrittlement. Utilize requires vacuum, idle gas, or encased situations when heated.
Q: How do you connect tantalum tubes to steel equipment?
Fusion welding makes fragile intermetallics. We utilize blast holding to steel tubesheets, flare fittings, or weld entirely to other tantalum components in dormant airs.
