High-Strength Forged Flange
With 21 years of precision production experience under its belt, LINHUI TITANIUM has been offering High-Strength Forged Flange solutions since 2003. To meet bulk requests, we produce 800 tons annually in two plants with thirty production lines and ISO/SGS/TUV quality certification. Our Forged Flange achieves tensile strengths up to 895 MPa (Grade 5) with dimensional tolerances of ±0.05mm by eliminating casting porosity through controlled forging. 100% ultrasonic and dye penetrant testing for zero-defect delivery is ensured by strict adherence to ASTM B381. International logistics via DHL, FEDEX, and sea freight ensures quick delivery to over 60 countries. Limited capacity; to request a quote within a day, send an email to linhui@lhtitanium.com.
Key Features & Benefits
Forged grain alignment increases fatigue resistance by 40% as compared to cast equivalents. The TiO2 passive layer provides defense against chloride stress corrosion cracking in harsh chemical environments, such as saltwater.
Grade 2 offers maximum ductility for chemical processing. Grade 5 (Ti-6Al-4V) provides aerospace-grade strength for high-pressure subsea applications. Surface finishes between Ra 3.2µm and Ra 0.8µm meet vacuum and hydrogen service requirements.

Manufacturing Process
Raw material undergoes PMI verification before entering forging. Billets are heated to 950°C–1050°C, then die-pressed to align grain flow with flange geometry.
Post-forging annealing at 700°C–850°C relieves residual stress. Alpha Case removal via machining ensures a clean, ductile surface. Final CNC machining achieves bolt hole tolerances per ASME B16.5
Quality Inspection
Every High-Strength Forged Flange passes 100% ultrasonic testing per AMS 2631 to detect internal voids. Dye penetrant inspection reveals surface hairline cracks before shipment.
Tensile and yield tests validate heat treatment success. CMM metrology confirms dimensional accuracy. Microstructure analysis verifies Alpha Case elimination. EN 10204 3.1 certificates document heat number traceability.

FAQ
Q: Can Grade 2 flanges withstand high-pressure service?
A: Class 150–600# moderate pressures are OK for Grade 2. For Class 900+, choose Grade 5 for improved tensile strength.
Q: How can galvanic corrosion be prevented in steel piping?
A: Use dielectric isolation kits (insulated gaskets, sleeves, and washers) to electrically separate titanium from steel.
Q: How much time does it take to receive customized sizes?
A: Depending on intricacy, production takes 25 to 40 days; designs are approved in a day.
Q: Do you provide services for third-party inspections?
A: Upon request, witness testing is offered for SGS, BV, TÜV, and DNV.
