As a specialized manufacturer with ISO-certified facilities spanning 1,000-3,000 square meters, Wuxi Weiman Gaodeng Special Steel produces premium titanium welded tubes for critical applications. Established in 2017, our advanced manufacturing capabilities enable us to deliver precision-engineered Gr1, Gr2, Gr7, and TA9 titanium alloy tubes that meet stringent industry requirements. These tubes combine exceptional corrosion resistance with high strength-to-weight ratios, making them ideal for chemical processing equipment and medical devices.
Core Technical Specifications:
Material Composition: Commercially pure titanium (Gr1/Gr2) and palladium-enhanced alloy (Gr7/TA9)
Corrosion Resistance: Withstands aggressive media including chlorides, acids, and alkalis
Temperature Tolerance: -196°C to 600°C operational range
Biocompatibility: Meets ISO 5832-2 standards for medical implants
| Grade | Tensile Strength (min) | Key Application |
|---|---|---|
| Gr1 | 240 MPa | Chemical heat exchangers |
| Gr2 | 345 MPa | Pharmaceutical piping |
| Gr7 | 345 MPa | Acid processing systems |
| TA9 | 620 MPa | Surgical instruments |
The welded construction ensures cost efficiency without compromising performance, with all joints undergoing non-destructive testing. Our proprietary cold-working process enhances structural integrity while maintaining precise dimensional tolerances of ±0.1mm. These tubes feature:
Internal surface roughness Ra ≤ 0.8μm for medical fluid transfer
Electropolished options available for ultra-clean applications
Custom end finishes (beveled, threaded, or flanged)
With 101-200 skilled professionals and annual exports valued at US$5-10 million, we serve global clients across North America, Europe, Asia, and Oceania. Our shipments depart from Shanghai, Ningbo, and other major Chinese ports, with flexible logistics solutions. The combination of our manufacturing expertise and titanium's innate properties delivers:
50-70% weight reduction compared to steel alternatives
Extended service life in corrosive environments
Reduced maintenance costs for processing plants
Frequently Asked Questions:
Q: What distinguishes Gr7 from standard titanium grades?
A: Gr7 contains 0.2% palladium, significantly enhancing resistance to reducing acids like sulfuric and phosphoric acid.
Q: Are these tubes suitable for implantable medical devices?
A: TA9 grade meets ASTM F136 standards for surgical implants, with optional certification documentation.
Q: What welding methods are employed?
A: We utilize autogenous TIG welding under argon shielding, ensuring contamination-free joints.
Q: Can you match specific chemical composition requirements?
A: Yes, we adjust alloying elements like oxygen and iron content per customer specifications.
Q: What quality control measures are implemented?
A: Each batch undergoes hydrostatic testing, eddy current inspection, and chemical analysis.
Q: Do you provide custom cutting services?
A: We offer precision cutting to required lengths with deburred edges at no additional cost.
