Key Features & Benefits
Corrosion Resistance Excellence
Our product resists aggressive media including seawater, chlorine, and acidic environments. Grade 7 variants with palladium addition offer superior performance in reducing acids.
Lightweight Yet Durable
Titanium density is 40% lighter than steel while maintaining exceptional strength. This reduces installation labor and structural load requirements.
Extended Service Life
Zero maintenance required in marine environments. The passive oxide layer self-heals, eliminating replacement costs for 20+ years.

Manufacturing Process
Billet Selection & Heating
Raw titanium billets undergo PMI testing before heating to 900–950°C in inert atmosphere furnaces. This prevents oxidation and ensures uniform grain structure.
Hot Forming
Hydraulic presses shape preheated billets into elbow geometry. Controlled cooling prevents residual stress accumulation that could cause service failure.
Welding (for Large Diameters)
Plate material is roll-formed and TIG welded without filler metal. The weld seam maintains base metal corrosion resistance properties.
Stress Relief Heat Treatment
Post-forming annealing at 650–750°C removes internal stresses. This restores ductility and prevents delayed cracking in corrosive environments.
Applications
Chemical Processing Plants
Your chlor-alkali production lines benefit from Grade 2 elbows that eliminate nickel alloy replacement costs. They handle wet chlorine gas at temperatures up to 150°C without degradation.
Marine Engineering
Shipbuilders specify our Pure Titanium Elbow fittings for seawater cooling systems. The weight reduction improves vessel fuel efficiency while resisting biofouling.
Desalination Facilities
Multi-stage flash (MSF) plants use Grade 7 elbows in brine heaters. The palladium addition prevents crevice corrosion in high-salinity environments exceeding 70,000 ppm TDS.
Pharmaceutical Manufacturing
Your clean-in-place (CIP) systems require contaminant-free piping. Our fittings meet FDA compliance for direct product contact in sterile fluid transfer.
Why Choose Us?
Coordinate Plant Pricing
Eliminate go betweens markups. You get mill-direct costs with full traceability by means of warm number documentation and EN 10204 3.1 certificates.
Rapid Reaction Times
Technical citations inside 4 hours. Drawing audits completed in 24 hours. Stock things dispatch inside 3–7 days.
Flexible Arrange Quantities
Trial orders begin at 100kg. Our 200-ton stock bolsters prompt small-batch necessities whereas scaling to container-load volumes.
Engineering Bolster Team
In-house metallurgists help with fabric review choice. We give welding strategy determinations (WPS) and rib separation proposals for mixed-metal systems.
Packaging & Shipping
Protection Standards
Each product is wrapped in bubble film and set in plywood cartons with shock-absorbing froth. Desiccants avoid dampness introduction amid sea transit.
Labeling Compliance
Heat numbers, fabric grades, and dimensional markings are laser-etched on each fitting. We give export-grade documentation counting commercial solicitations and pressing lists.
Logistics Partners
DHL/FedEx for tests (3–5 days worldwide conveyance). Discuss cargo for pressing orders (7–10 days). Ocean cargo for bulk shipments (20–35 days with holder tracking).
Export Markets
We've conveyed over 5,000 tons of titanium fittings to 60+ countries:
North America: USA, Canada, Mexico
Europe: Germany, UK, France, Netherlands
Middle East: UAE, Saudi Arabia, Qatar
Asia-Pacific: South Korea, Japan, Singapore, Australia
Long-term organizations incorporate chemical temporary workers like PTT and PETRONAS, furthermore maritime shipyards in South Korea and Japan.
Quality Inspection
Dimensional Verification
CMM gear measures center-to-face separate, exterior breadth, and divider thickness per ASME B16.9 resistances. Our acknowledgment criteria: ±0.5mm for distance across, ±0.1mm for divider thickness.
Non-Destructive Testing (NDT)
100% ultrasonic testing (UT) on consistent elbows recognizes inside laminations. All welded the item fittings experience radiographic testing (RT) to recognize porosity.
Surface Quality Control
Dye penetrant review (DPI) uncovers surface breaks or laps. Our acknowledgment standard: zero direct signs surpassing 3mm.
FAQ
Q: What's the contrast between consistent and welded elbows?
A: Consistent elbows (Φ10–Φ108) are expelled from strong billets, perfect for high-pressure basic frameworks. Welded elbows (Φ108–Φ680) are shaped from plate with TIG-welded creases, cost-effective for huge distances across after 100% RT inspection.
Q: Can I interface titanium elbows to stainless steel pipes?
A: Coordinate contact in electrolytes causes galvanic erosion. Utilize spine confinement units with protection gaskets and sleeves to anticipate stainless steel degradation.
Q: How do I select between Long Span and Brief Span elbows?
A: Select LR (1.5D) for standard channeling to minimize weight drop. Select SR (1.0D) as it were when space limitations exist, noticing it increments stream turbulence by 30%.
Q: Does the elbow require post-weld warm treatment?
A: Per ASTM B363, stretch help at 650°C is required after shaping. This avoids hydrogen embrittlement and reestablishes ductility for destructive service.
Q: Why is Review 2 most common?
A: Review 2 equalizations erosion resistance, formability, weldability, and taken a toll. It handles most mechanical situations whereas being 40% cheaper than Review 5 combinations.
