Titanium Alloy Pipes and Tubes
Titanium alloys are a critical structural material in the nuclear power industry, offering key advantages including excellent corrosion resistance, high specific strength (high strength-to-weight ratio), good radiation resistance, and low neutron activation characteristics. Depending on specific service environments, titanium alloy products have been widely used in various critical applications, including nuclear power plant cooling systems, nuclear fuel reprocessing, and nuclear-powered vessels. Titanium alloy pipes and tubes are core components of nuclear power plant cooling systems — particularly in scenarios where seawater is used as the cooling medium, their advantages are truly irreplaceable.

Product Features
  • Material: High strength and high toughness with excellent overall performance. TA24 exhibits an outstanding combination of strength and ductility at room temperature. In the annealed condition, it achieves a measured tensile strength of 886 MPa, a yield strength of 836 MPa, while maintaining an elongation of 19.5% and a room-temperature impact energy of 85 J. This exceptional combination of high strength and toughness makes it well-suited for critical large-scale structural components such as deep-sea pressure hulls and propulsion shaft systems.

  • Excellent Seawater Corrosion Resistance: Titanium alloys, renowned as "marine metals," exhibit exceptional corrosion resistance in seawater environments. TA24 effectively resists localized corrosion issues such as pitting and crevice corrosion, allowing seawater piping systems to be designed with flow velocities exceeding 10 m/s. This capability significantly enhances system reliability while also enabling weight reduction.

  • Excellent High-Temperature Performance: As a near-α alloy, TA24 maintains good mechanical properties at temperatures as high as 550°C. Research data shows that it achieves a tensile strength of 445 MPa at 550°C and still retains 352 MPa even at 650°C.

  • Excellent Weldability and Processability: TA24 offers outstanding welding performance, with welded joints exhibiting high strength. Through post-weld heat treatment at 650–750°C, an optimal balance between strength and ductility can be achieved.

  • Dimensional Accuracy Assurance: The machining process follows a sequence of roughing, medium roughing, semi-finishing, and finishing on CNC machining centers. Finished products are inspected using CMM (coordinate measuring machine) inspection and GOM 3D scanning to ensure product quality.

  • Anti-deformation Process: TA24 material is prone to deformation during machining. We adopt a cutting process combining stress relief and coolant-assisted cold cutting, ensuring that flatness after machining is controlled within 0.1 mm per meter.

  • Custom Cutting Tools: TA24 material tends to cause rapid tool wear during machining. Based on the compositional characteristics of this material, we have developed custom cutting inserts specifically designed for machining it. This increases cutting efficiency by 60–80% and reduces tooling costs by 50–60%.

  • Typical Customers: Leading nuclear power companies both domestically and internationally.

  • CMM Inspection: After product machining is completed, GOM scanning inspection is performed on the product and an inspection report is issued.
