Titanium Welded Tube
THT is one of the leading titanium welded pipe suppliers in China. Our titanium welded pipes are processed through automated continuous production lines, using titanium strip coils with uniform wall thickness. They undergo cold bending, welding with online heat treatment, sizing and straightening, non-destructive testing, and air tightness testing processes, achieving a material utilization rate of around 80%, from sponge titanium to finished titanium pipes.Our titanium welded pipes feature the following characteristics:
- High precision of pipe-making machine, minimal axial runout: We employ advanced pipe-making machinery to ensure the production precision of titanium welded pipes and minimize axial runout, ensuring stable and reliable product quality
- 100% X-ray inspection of weld seams: We strictly adhere to the standard of 100% X-ray inspection of weld seams to ensure that there are no internal defects, meeting the highest safety standards.
- Weld seams present a fish scale pattern, silver-white in color: The surface of our weld seams is smooth, presenting a fish scale pattern, and possesses a silver-white appearance, which is aesthetically pleasing.

Titanium Welded Tube VS Titanium Seamless Tube
1. Different production processes: Titanium welded pipes are mainly made through welding processes, while titanium seamless pipes are mainly made through rolling processes
2. Different performance characteristics of titanium pipes: Due to different production processes, the roundness and wall thickness of titanium seamless pipes are better than those of titanium welded pipes. Under high temperature and high pressure, titanium seamless pipes are more corrosion-resistant and pressure resistant than titanium welded pipes
3. Different production standards: The main production standards for titanium welded pipes are ASTM B338, ASTM B862, etc., while the main production standards for titanium seamless pipes are ASTM B338, ASTM B861, etc
4. Price difference: The rolling process of titanium seamless pipes is complex and the cost rate is low. Under the same specifications, titanium welded pipes are much more competitive than titanium seamless pipes
Application
Titanium welded pipes are suitable for low-pressure applications and pipeline systems, with different grades serving different purposes.
GR1 titanium welded pipes are primarily used for heating elements, exhaust systems, titanium water cups, as well as applications requiring bending or shaping.
GR2 and GR12 titanium welded pipes are commonly used in the manufacturing of chemical equipment, such as heat exchangers, condensers, reactors, pipeline systems, etc. In chemical equipment applications, GR2 is recommended for fluid temperatures at ambient levels, while GR12 is recommended for higher fluid temperatures.
Titanium Grade 5 (Ti-6Al-4V) pipes are typically utilized in aerospace, medical, chemical processing, marine, sports, and oil and gas industries. Their high strength, corrosion resistance, and lightweight properties make them well-suited for applications including aircraft components, implants, chemical equipment, shipbuilding, sports equipment, and components in the oil and gas sector.
