FAQ
Q: 1. How are titanium elbows classified by bending method, and what are their applications?
A: According to radius and bending angle, titanium elbows are mainly classified as follows:
| Dimension | Type | Key Parameter | Application |
|---|---|---|---|
| Radius | Long radius (R=1.5D) | Radius = 1.5 × pipe OD | General applications, mainstream choice |
| Short radius (R=1.0D) | Radius = 1.0 × pipe OD | Space‑limited, compact layouts | |
| Angle | 45°, 90°, 180° | Standard angles | Conventional directional changes |
| Special angles | Customized as needed | Special layout requirements | |
| Manufacturing | Seamless / Butt‑weld | Integral forming | High pressure, high safety requirements |
| Welded, stamped, cast | By process | Cost‑performance trade‑off |
Selection principle: For most projects, use 90° long‑radius elbows. Short‑radius elbows may be used when space is limited and pressure is low. For high-pressure or high-sealing requirements, choose seamless or butt‑weld elbows. Special‑angle elbows can be custom‑ordered.
Q: 2. How do titanium elbows perform in corrosive and high‑temperature environments? Which grades are suitable for which media?
A: The core advantages of titanium elbows are excellent corrosion resistance and high‑temperature performance. In air and oxygen‑containing media, titanium instantly forms a dense, stable TiO₂ passive film that self‑repairs quickly if damaged. The corrosion rate is extremely low (<0.001 mm/year) in chlorides, seawater, wet chlorine, nitric acid, etc.
Grade characteristics and typical applications:
| ASTM equivalent | Max. temp. | Features | Typical applications |
|---|---|---|---|
| Gr.1 | ≤300°C | Very low impurities, best formability & weldability, lower strength | Mild corrosive environments where forming is critical |
| Gr.2 | ≤300°C | Balanced performance, best cost‑effectiveness, and most commonly used | Seawater, chlor‑alkali brine, wet chlorine, oxidizing acids, pressure ≤10 MPa |
| Gr.7 | Same as TA2 | ~0.2% Pd added, greatly improved resistance to reducing acids and crevice corrosion | Dilute HCl, H₂SO₄, severe crevice corrosion conditions |
| Gr.12 | Same as TA2 | Mo + Ni addition, excellent crevice corrosion resistance, more economical than TA9 | Oil & gas pipelines containing chlorides, heat exchanger sealing faces |
| Gr.5 | ≤450°C | α+β alloy, very high strength (UTS ≥895 MPa), good overall mechanical properties | High‑pressure valve stems, downhole tools requiring high strength and corrosion resistance |
Corrosion resistance data:
Chloride (Cl⁻) tolerance: >20,000 ppm – eliminates the SCC issue of stainless steel
High temperature: TA2 up to 300°C (short‑term 600°C); TC4 up to 450°C
Corrosion rate in boiling HCl, HNO₃, chlor‑alkali media: <0.018 mm/year – 15× better than stainless steel
In the wet chlorine (chlor‑alkali industry), TA2 elbows last >10 years
Special cautions:
Titanium must not be used with liquid or dry chlorine (moisture <0.5% may cause combustion). Wet chlorine is safe.
In oxygen‑free, high‑temperature concentrated reducing acids (e.g., concentrated HCl, H₂SO₄), the passive film may be unstable.
Titanium must not be used with fuming nitric acid containing <2% water or >6% free NO₂.
Q: 3. What pressure and cyclic stress can titanium elbows withstand?
A: Thanks to the high strength and low density of titanium, titanium elbows outperform stainless steel in both pressure capacity and fatigue resistance.
Pressure capacity:
Gr2 industrial pure titanium elbows: working pressure ≤10 MPa
Titanium alloy elbows can reach 30 MPa with optimized wall thickness
Tensile strength: Gr2 345–480 MPa, Gr12 480–620 MPa, Gr9 620–800 MPa
Fatigue resistance:
Gr2 elbows: fatigue limit ~600 MPa, life >10⁷ cycles under alternating stress – suitable for vibrating environments
Gr5 after high‑pressure heat treatment: fatigue strength increased by 80%, crack growth rate reduced to ~10⁻⁶ mm/cycle
Density of titanium = 4.5 g/cm³ (~60% of steel) – lower inertial load delays fatigue crack initiation
