Grade 7 Titanium Alloy Pipe Manufacturer - Daxun Alloy
Provide High Quality Grade 7 Titanium Pipe to Customers Around The World
Grade 7 titanium pipe is a palladium-enhanced commercially pure titanium alloy (Ti-0.12Pd), engineered for ultimate corrosion resistance in the most aggressive environments. It combines the inherent formability and weldability of pure titanium with exceptional durability against reducing acids and chlorides. Its density (4.51 g/cm³) is approximately 60% that of steel, while offering unparalleled defense against chemical attack, pitting, and crevice corrosion. The alloy excels in harsh conditions—including hot reducing acids, chloride-rich solutions, and sour gas environments—maintaining integrity where other materials fail.
- Palladium’s electrochemical role: Pd acts as a cathodic catalyst, promoting rapid repassivation of the titanium oxide layer when damaged. This self-healing mechanism prevents localized corrosion (pitting/crevice) in reducing acids like HCl, H₂SO₄, and wet chlorine environments where conventional titanium fails.
- Synergy with titanium matrix: While retaining pure titanium’s inherent ductility and weldability, the Pd dopant creates a barrier against hydrogen embrittlement and stress corrosion cracking (SCC), enabling reliable performance in chemically aggressive media
Where is Grade 7 titanium pipe used?
In chemical processing plants, it’s the material of choice for reactor vessels, heat exchangers, and piping systems handling sulfuric acid, hydrochloric acid, and chlorinated organics due to its inertness. Marine and offshore industries rely on it for critical seawater systems, desalination equipment, and subsea components, leveraging its unmatched resistance to saltwater corrosion and biofouling. Oil and gas operations employ it in downhole tubing, Christmas tree components, and sour gas pipelines where high-pressure H₂S and CO₂ environments cause rapid degradation of standard alloys. Pharmaceutical and biotech facilities use it for ultra-pure water systems and chemical delivery lines, ensuring zero contamination. Additionally, nuclear waste treatment e pollution control systems utilize it for scrubbers and condensers exposed to corrosive flue gases and acidic effluents, combining longevity with absolute reliability.
Key Performance:
Strength-Ductility Balance:
- Tensile Strength: 483 MPa (annealed state) – Matches Grade 2 but with superior corrosion resistance.
- Elongation: ≥20% – Exceptional ductility for cold forming and high fatigue resistance.
- Density: 4.51 g/cm³ – 60% lighter than steel, ideal for weight-sensitive applications.
Corrosion Resistance:
- Palladium-enhanced performance: Resists pitting/crevice corrosion in seawater, chlorides, reducing acids (HCl, H₂SO₄), and sour gas (H₂S).
- Outperforms Grade 2/9: Immune to corrosion in oxidizing media and aggressive chemical environments where stainless steel fails.
- Galvanic compatibility: No risk of galvanic corrosion when paired with dissimilar metals.
Weldability & Processability:
- Welding: Excellent TIG/laser weldability – no post-weld cracking due to Pd stabilization.
- Forming: Superior cold workability vs. Grade 5; easily formed into tubes, sheets, and complex shapes.
- Heat Treatment: Stress-relieved at 480–595°C to optimize corrosion resistance and ductility.
Application Advantages:
- Chemical Processing: Reactors, piping, heat exchangers – handles hot reducing acids, chlorides, and sour gas.
- Marine: Desalination plants, seawater cooling systems – lifetime immunity to saltwater corrosion.
- Aeroespacial: Hydraulic fluid lines – lightweight durability in corrosive fuel/hydraulic environments.

Caraterísticas principais
- Strength-to-Weight Ratio: Comparable to pure titanium (Grades 1–4) but lower than Ti-6Al-4V (Grade 5) or Ti-3Al-2.5V (Grade 9). Optimized for corrosion resistance over mechanical strength.
- Corrosion Resistance: Unmatched in reducing acids (e.g., HCl, H₂SO₄), chlorides, and crevice corrosion environments. Outperforms all commercially pure grades (1–4) and Grade 5/9 in aggressive chemical media due to palladium (Pd) stabilization.
- Biocompatibility: Fully non-toxic and MRI-compatible. Suitable for surgical instruments and chemical processing equipment, though not used for permanent implants (Grade 23 preferred).
- Formability: Retains excellent cold formability, weldability, and machinability of pure titanium. Significantly easier to fabricate than Grade 5/9, enabling complex geometries without specialized tooling.

Grade 7 titanium tube form (4)
-
Titanium seamless tubes are made by piercing and drawing solid titanium bars, and the hollow part of the tube is made by piercing or hot extrusion. Titanium seamless tubes are ideal for very large diameter to wall thickness ratios and have very good external dimensional tolerances.
-
Titanium welded pipe is a tubular product made of strip titanium that is roll formed and fusion welded along the longitudinal seam. The welding process used by Daxun Alloy does not use any filler metal during the welding process.
-
Titanium square tubes are drawn from round tubes or round tube billets and can be formed into right angles or rounded corners. They can also be cold extruded, which is efficient and low cost. The only disadvantage is that the tolerance will gradually increase.
-
Tubular products are welded and then re-drawn to final size. Welding and drawing is ideal for producing thick walled, large diameter tubes that cannot be welded directly to size but still offer cost savings over seamless tubes. All Daxun welded and drawn tubes are bright annealed.

O tipo de liga de titânio de que necessita depende do projeto em que está a trabalhar, uma vez que cada tipo tem benefícios diferentes.
Todos os graus de liga de titânio são extremamente fortes e resistentes à corrosão, o que significa que continuarão a funcionar bem nas condições mais adversas.
Os graus mais elevados de liga de titânio (5-12) são ligas concebidas para benefícios específicos. Por exemplo, a liga de titânio de grau 12 tem uma excelente resistência ao calor, o que a torna uma escolha perfeita para permutadores de calor de casco e tubo, tubagens hidráulicas e equipamento da indústria química.
Os graus 1-4 são ligas de titânio puro e são a escolha perfeita se precisar de um material soldável e dúctil para sistemas de tubagem e tubos. Encontrará graus inferiores utilizados nas indústrias marinha e industrial.
Se está a iniciar um projeto e não tem a certeza de qual o melhor tipo de liga de titânio para si, contacte-nos hoje mesmo; teremos todo o gosto em ajudá-lo.
Na DAXUN, oferecemos uma vasta gama de graus de liga de titânio, do grau 1 ao grau 12.
Os graus 1-4 são titânio puro, enquanto os graus superiores são ligas.
Os tipos de liga são populares pela sua elevada relação resistência/peso.
O grau de liga de titânio mais utilizado que encontramos é o grau 5. Embora continue a ser rica em titânio, esta classe é uma das mais fiáveis porque pode suportar temperaturas até 600°F e resistir a condições extremas.
As qualidades superiores são preferidas por indústrias como a aeroespacial e a marítima devido à sua resistência ao desgaste e à corrosão.
Por outro lado, os graus inferiores são utilizados principalmente para soldadura devido à sua menor resistência.
