- Product Description
Titanium Welded Tube - High-Performance Tubular Solutions from Baoji Jucheng
Baoji Jucheng Titanium Industry Co., Ltd., located in China's Titanium Valley, manufactures premium titanium welded tube with over 20 years of specialized experience. Our production capabilities include OD6–OD1020mm with wall thickness from 0.5mm to 12mm, available in lengths up to 6000mm. Manufacturing over 500 sets of titanium equipment annually and maintaining 3,000 tons of titanium inventory, we ensure fast delivery cycles 30-50% shorter than seamless alternatives. Our welded tube is manufactured to ASTM B862 and ASME SB862 standards, utilizing automatic welding with post-weld heat treatment achieving weld joint efficiency of 1.0. Available in Gr1, Gr2, Gr5, Gr7, Gr9, and Gr12, each tube undergoes strict quality inspection backed by our 4 invention patents and 41 utility model patents.

What Makes Our Titanium Welded Tube Superior
High-quality titanium plate cutting is the first step in the production process. Precision rolling and automated welding with complete penetration and treatment come next.
During welding, both internal and external surfaces are shielded by high-purity argon gas. This stops oxidation and pollution of the atmosphere.
The weld zone microstructure is restored to the parent metal's characteristics through post-weld annealing. As a result, mechanical performance is comparable to seamless tubes at a substantially reduced cost.
Compared to extruded seamless goods, our cold-rolled strip feedstock produces better surface finishes. In liquid media applications, this smoother surface lowers fouling rates.
On the surface, the stable TiO2 oxide layer quickly develops. In settings high in chloride, it offers self-healing defense against pitting and stress corrosion cracking.

Industrial Applications
Chemical Processing: Shell-and-tube heat exchangers handling reducing acids benefit from our Gr7 options. The material withstands aggressive interfaces between process fluids and cooling water.
Desalination Systems: Brine heaters and multi-stage flash evaporators operate in high-temperature, high-chloride environments. Our tubes prevent crevice corrosion at tube-to-tubesheet joints above 80°C.
Marine Engineering: Seawater cooling systems and condensers utilize Grade 2 for optimal corrosion resistance. Thermal conductivity approximately 50% higher than stainless steel improves heat transfer efficiency.
Hydrometallurgical Extraction: Acid leaching autoclaves for nickel, cobalt, and gold extraction require materials that withstand high temperature, pressure, and acidic slurries. Standard stainless steel fails where our titanium welded tube excels.
Food and Pharmaceutical: Sanitary processing equipment benefits from the smooth surface finish and biocompatibility of titanium tubing.

Frequently Asked Questions
Q: Is the weld seam a weakness compared to seamless tube?
A: No. When manufactured to ASTM B338 standards with proper heat treatment, weld joint efficiency reaches 1.0. The weld strength equals the base metal strength.
Q: Can welded tubes replace seamless in heat exchangers?
A: Yes, for most low-to-medium pressure applications. You benefit from better wall thickness uniformity and reduced costs while maintaining performance.
Q: What grade should I choose for my application?
A: Grade 2 offers the best balance of strength, ductility, and corrosion resistance for general applications. Grade 7 provides enhanced crevice corrosion resistance in high-temperature chloride environments above 80°C.
Q: Can these tubes be bent for U-bend heat exchangers?
A: Absolutely. The annealed weld and excellent strip ductility allow tight radius bending. We recommend stress relief annealing after bending for optimal performance.
Q: How does your surface finish compare?
A: Our cold-rolled strip feedstock produces smoother surfaces than seamless extrusion. You experience reduced fouling and easier cleaning in service.
