Titanium Weld Neck Flanges for High-Pressure Industrial Piping
TSM Technology manufactures precision Titanium Weld Neck Flanges at its 60,000-square-meter forging and machining center in Baoji, Shaanxi Province. Our flanges are designed for critical piping systems with extremely high integrity and corrosion resistance requirements and are manufactured strictly according to ASME B16.5, ASME B16.47, and ASTM B363 standards.
When choosing titanium alloy welded neck flanges, more than just the product itself is needed; verified materials, precise machining tolerances, and traceability are also crucial. As a direct manufacturer, TSM eliminates intermediaries, ensuring you receive certified components with consistent metallurgical properties.
Engineering Specifications & Material Standards
The defining feature of Titanium Weld Neck Flanges is the long tapered hub that transitions the stress from the pipe to the flange, significantly reducing concentration at the base. This design is critical for applications involving high pressure, sub-zero temperatures, or cyclic loading.
| Standard | Specification |
|---|---|
| ASTM B363 | Standard Specification for Seamless and Welded Unalloyed Titanium and Titanium Alloy Welding Fittings |
| ASME B16.5 | Pipe Flanges and Flanged Fittings (1/2" through 24") |
| ASME B16.47 | Large Diameter Steel Flanges (NPS 26 through NPS 60) |
Selecting the Right Titanium Grade for Your Application
Choosing the correct material for your Titanium Weld Neck Flanges is determined by the fluid medium, temperature, and pressure. Our metallurgical team works closely with engineers to ensure the material grade matches the process environment.
| Grade | Ti (min %) | Key Alloy Elements | Tensile (ksi, min) | Yield (ksi, min) |
|---|---|---|---|---|
| Grade 2 | 99.2 | Fe ≤0.30, O ≤0.25 | 50 | 40 |
| Grade 5 (Ti-6Al-4V) | 90 | Al 6.0, V 4.0 | 130 | 120 |
| Grade 7 | 99.1 | Pd 0.12–0.25 | 50 | 40 |
| Grade 12 | 99.0 | Mo 0.3, Ni 0.8 | 70 | 50 |
Manufacturing Capability: The TSM Advantage
Located in Shaanxi, China, our facility leverages the local supply chain advantage to offer unrivaled lead times for custom Titanium Weld Neck Flanges. Unlike distributors who manage long supply chains, TSM manages the entire production cycle:
Raw Material Forging: We begin with high-quality titanium ingots, ensuring the starting material complies with ASTM chemical composition limits before it reaches the press.
Precision Machining: Our CNC lathes maintain the strict tolerances required for the raised face (RF) or ring-type joint (RTJ) surface finishes.
Butt-Weld Preparation: The weld bevel is machined to match specific pipe schedules (Sch 10S, 40S, 80S, etc.), ensuring seamless integration during site installation.
Dimensions and Tolerances
Our Titanium Weld Neck Flanges are manufactured to ensure full compliance with the dimensional requirements of ASME B16.5. This includes specific attention to the bore diameter, flange thickness, and bolt hole alignment. We understand that even a minor deviation can lead to misalignment on-site, causing costly project delays. Our quality team verifies:
Hub Taper: Correct slope for stress distribution.
Raised Face Height: Precision machined to 1.6mm or 6.4mm as per Class 150/300 requirements.
Bolt Hole Pitch: Guaranteed accuracy for rapid bolt-up.
Quality Assurance and Testing Protocols
As a leading supplier of Titanium Weld Neck Flanges, TSM Technology Co. implements a rigorous Quality Management System (QMS). We do not release product without comprehensive documentation.
Every shipment includes a Mill Test Report (MTR). Our standard testing includes:
Chemical Analysis (PMI): Verification of elements including Oxygen, Nitrogen, Hydrogen, Iron, and Carbon.
Mechanical Testing: Tensile strength and yield strength verification.
Non-Destructive Testing (NDT): Ultrasonic Testing (UT) for internal defects and Dye Penetrant Testing (PT) for surface integrity.
Dimensional Inspection: Full measurement report against requested standards.
Why Choose TSM?
When sourcing your inventory of Titanium Weld Neck Flanges from TSM Technology Co., your engineering team deals directly with the primary manufacturer. This bypasses international broker networks and trading agencies, shortening communication lines and preventing technical misinterpretations regarding material specifications.
Our primary production base located in Shaanxi leverages direct integrations with domestic premium titanium sponge reduction facilities. This allows us to secure stable raw material pricing and insulate our international clients from sudden material market volatility. Furthermore, our internal inventory management system holds a constant supply of pre-forged semi-finished blanks. This system allows us to complete precision finish machining, face profiling, and dimensional inspections within accelerated timeframes, outpacing standard European or American distribution networks by several weeks.
Custom Fabrication & OEM Services
While we maintain stock of standard Titanium Flanges, we specialize in custom manufacturing. If your project requires non-standard dimensions, specific titanium alloys, or large-diameter flanges (ASME B16.47 Series A or B), TSM has the technical capacity to manufacture to your drawings.
Whether you require a one-off custom flange for an emergency repair or a large-scale project supply, our engineers are ready to review your specifications. Simply upload your CAD files or datasheets, and we will provide a feasibility assessment and quotation.
Package
Every flange is individually wrapped in VCI paper, fitted with protective flange covers, and crated in ISPM 15 heat-treated wood. Our shipping team manages air freight, sea LCL/FCL, and express courier documentation. We routinely deliver to Houston, Rotterdam, Jebel Ali, and Singapore within 8–21 days from order confirmation, depending on size and finishing requirements.
