High Neck Flange - Premium Titanium Piping Component
LINHUI TITANIUM manufactures enterprise-grade High neck flange products with certified 99.9% titanium content, delivering exceptional corrosion resistance and sealing performance. Our customized specifications feature precision-engineered components weighing 2Kg with a particle size of 200, specifically designed for critical industrial applications. Each flange undergoes strict quality control to meet ASTM B381 standards, offering superior structural integrity through tapered hub design that eliminates stress concentration points.
Our advanced manufacturing process ensures zero turbulence at pipe joints. The butt-weld construction provides seamless internal connections, ideal for high-pressure and high-temperature systems where reliability is non-negotiable.
Key Features & Benefits
Superior Stress Distribution
The tapered hub transfers operational stress from the flange to the pipe, reducing fatigue failure risk by up to 60% compared to standard flanges.
Zero Turbulence Design
Machined bore matches pipe internal diameter precisely, eliminating erosion-corrosion at connection points in high-velocity flow systems.
Extreme Corrosion Resistance
Titanium construction withstands aggressive media including chlorine gas, sulfuric acid, and seawater for 20+ year service life.

Manufacturing Process
Forging Stage
High-purity titanium ingots undergo controlled forging at 900°C, creating uniform grain structure for enhanced mechanical properties.
Heat Treatment
Stress-relief annealing at 650°C for 2 hours ensures dimensional stability and eliminates residual stress from forming operations.
Precision Machining
CNC machining achieves bore tolerance within ±0.05mm. Tapered hub geometry is programmed to match exact pipe wall transitions, ensuring smooth stress flow.
Surface Treatment
Acid pickling removes oxide scale, followed by passivation to enhance natural corrosion-resistant film formation.
Quality Inspection
100% NDT Testing
Every High neck flange undergoes ultrasonic and eddy current inspection to detect subsurface defects before shipment.
Dimensional Verification
CMM (Coordinate Measuring Machine) confirms all critical dimensions meet drawing specifications within ±0.1mm tolerance.
Pressure Testing
Hydrostatic testing performed at 1.5x design pressure to validate structural integrity under operational conditions.
Third-party inspection available through SGS, BV, TÜV, and DNV upon request.
Applications
Offshore Gas and Oil
vital for riser systems and subsea manifolds where optimum joint reliability is required due to dynamic load from ocean currents.
Processing Chemicals
prevents dead zones where corrosive deposits build up in conventional fittings by managing aggressive media in chlor-alkali plants.
Generation of Power
Utilized in desalination facilities and superheated steam lines, it can withstand high temperatures without causing seal deterioration.
Refineries for Petrochemicals
transports cryogenic LNG and volatile fluids with little erosion caused by turbulence at connection locations.
