Core Products: Engineered for Harsh Chloride Environments & Lightweight Demands
The excellence of titanium lies in its ability to form an extremely stable and self-healing oxide film when exposed to oxidizing media, especially chloride-containing environments. Our product line is precisely positioned for this.
Compared to stainless steel, Titanium valve balls exhibit near-perfect, inert corrosion resistance in seawater, wet chlorine, chloride solutions, and various oxidizing acids. The TA1 valve balls we provide, representative of commercially pure titanium, combine excellent formability, weldability, and cost-effectiveness. They are the ideal upgrade to replace stainless steel balls in such environments, significantly extending equipment life and eliminating corrosion leak risks.
Forging Unlocks Superior Performance
For critical applications demanding higher strength and reliability, we offer Forged titanium valve balls. The forging process effectively refines the as-cast structure, significantly grain-refining, and eliminates internal defects, thereby greatly enhancing the ball's fatigue strength, fracture toughness, and consistency of mechanical properties. This makes them the preferred core for valves in high-pressure, high-cycle, or safety-critical services.
Precision Products for Various Valve Architectures
We provide precision titanium balls suitable for all types of valve designs:
- Floating titanium valve balls: Optimized for floating ball valve designs. Leveraging titanium's low density, they further reduce valve operating torque, unifying corrosion resistance with operational ease.
- Precision titanium valve balls: Regardless of the design, we ensure products achieve exceptional geometric accuracy (sphericity, dimensional tolerances) and surface finish. For titanium, precise dimensional control is fundamental to ensuring reliable sealing with various seat materials.
Technical Focus: Overcoming Manufacturing Challenges of "Low Stiffness" and "Reactive Surface"
Machining titanium is a true test of a manufacturer's expertise, with its low elastic modulus (prone to deflection) and high chemical activity being the two core challenges.
Strategy Against Low-Stiffness Deflection:
In manufacturing Precision titanium valve balls, we adopt a multi-step, light-depth-of-cut machining approach and design dedicated fixtures to meticulously counteract the elastic deflection of titanium under cutting forces, ensuring ultimate dimensional stability and form accuracy.
Processes Controlling Chemical Reactivity:
To prevent oxidation and hydrogen pickup (which can lead to embrittlement) during machining due to high temperatures and air exposure, we employ cutting fluids with special additives for sufficient cooling and lubrication. Vacuum annealing is scheduled after key processes to relieve machining stresses and purify the surface.
Proprietary Surface Treatment Technology:
We avoid traditional pickling processes that risk hydrogen embrittlement or contaminant introduction. Instead, we utilize a combination of mechanical polishing and controlled electropolishing to prepare a clean, uniform, passivated surface rich in stable titanium oxide for Titanium balls, ensuring their long-term corrosion resistance.
