Precision CNC Machining China Custom Titanium Alloy Pressure Vessel Manufacturing

As a technical engineer specializing in titanium alloy processing, I focus on the manufacturing of pressure vessels that require precision and reliability. These vessels are machined from titanium grades like TA2, TA9, TA10, or TC4 using CNC centers to ensure uniform wall thickness and structural integrity. Titanium alloy offers high strength-to-weight ratio and exceptional corrosion resistance, making it ideal for extreme operating conditions. Our production process adheres to strict pressure vessel standards, from initial material cutting to final assembly. For instance, we employ K-TIG deep penetration welding to achieve full penetration in single passes, minimizing heat input and avoiding defects like porosity. This approach ensures safety under high-pressure or cryogenic environments.

1. Superior Corrosion Resistance: Resists most acidic and alkaline media (e.g., NaOH, KOH). In a chemical project, vessels exposed to dye intermediates showed no pitting after 5 years of service.
2. High Strength and Lightweight: Tensile strength exceeds stainless steel with 40% weight reduction, critical for aerospace and mobile equipment.
3. Broad Temperature Tolerance: Operating range from -269°C to 650°C (depending on material). Tests at -196°C (liquid nitrogen) under 330 bar pressure confirmed structural stability.
4. Precision Machining: CNC milling and turning ensure accuracy (±0.1mm) for flanges and heads. For composite structures, explosion bonding securely joins titanium layers to substrates like 16MnR.
5. Customization Options: Configurable with jackets for heating/cooling, agitation systems (anchor/paddle types), and multiple ports (gas inlet, sampling), with variable speed control (0-500r/min).

• Chemical and Dye Industries: Reactors for sulfidation, nitration, and polymerization, resistant to corrosive agents.
• Aerospace: Propellant tanks for liquid oxygen/nitrogen, validated at -196°C.
• Pharmaceutical and Food: GMP-compliant vessels preventing metal ion contamination.
• Energy and Metallurgy: Hydrogen storage systems and high-pressure extraction units.

We offer end-to-end solutions from design to production. For example, we developed a dual-temperature vessel (-50°C cryogenic to 230°C heating) using TA10 alloy and a segmented jacket design for rapid thermal switching. Services include 3D modeling, stress simulation (FEA), and compliance with ASME/GB standards. For small batches (e.g., 12 units), lead time is 4-6 weeks.

• Technical Consultation: Free material selection guidance (e.g., comparing pure titanium vs. alloys).
• Testing: Each vessel undergoes hydrostatic tests, leak checks, and X-ray weld inspection.
• After-Sales: Installation support, maintenance reminders, and lifetime warranty for structural defects.
