Forged flange

Forged Flange - High-Performance Titanium Pipeline Connection Solutions

Forged flange components that satisfy the most exacting industrial specifications are LINHUI Titanium's specialty. Our products offer customized sizes with nominal diameters ranging from 1/2'' to 48'' inch (DN15mm-DN1800mm), and they meet ANSI, JIS, DIN, and GB standards.

Advanced forging techniques are used to precisely engineer each flange, resulting in continuous grain flow structures that avoid porosity problems typical of cast alternatives. For high-pressure applications up to Class 2500, we guarantee zero-defect quality with 100% NDT inspection and thickness tolerance managed within ±0.05mm.

Our titanium flanges are perfect for weight-sensitive offshore and aerospace installations because they provide an exceptional strength-to-weight ratio at about 60% the density of steel.

Important Features & Advantages

Enhanced Structural Integrity: By coordinating metal grain flow with flange geometry, the forging technique significantly improves impact toughness and fatigue resistance when compared to cast counterparts.

Superior Corrosion Resistance: Our forged flange products provide resistance to stress corrosion cracking and pitting brought on by chloride in seawater and extremely acidic conditions, where stainless steel fails.

Lightweight Performance: Titanium's density of 4.51 g/cm³ enables significant weight reduction without compromising strength, which is crucial for offshore FPSO topsides and aircraft hydraulics.

Thermal Stability: Reliability in the face of abrupt temperature changes without fracturing is made possible by a low coefficient of thermal expansion.

Product Information

Production Procedure

Forging Operations: Raw titanium billets are hot forged at controlled temperatures to produce refined grain structures and continuous metal flow that eliminates internal flaws.

Heat Treatment: Stress-relief annealing maximizes mechanical attributes and provides dimensional stability for your individual pressure and temperature needs.

Precision Machining: CNC processing creates hub profiles, sealing faces, and bolt holes with exact dimensional tolerances in accordance with your technical standards.

Surface Treatment: Post-machining pickling removes Alpha Case, an oxygen-enriched brittle layer formed during forging, and restores full corrosion resistance.

Applications Of Forged flange

Offshore Oil & Gas: Subsea manifold connections, topside piping, and seawater injection systems where weight reduction and chloride resistance are crucial.

Wet chlorine gas, brine solutions, corrosive acid systems that need leak-proof connections, and chlor-alkali facilities are all part of chemical processing.

Heat exchanger connections and pipe systems in desalination facilities are subjected to extremely high saline levels, necessitating little maintenance.

Power Generation: Condenser cooling systems and FGD (flue gas desulfurization) applications in coastal facilities where traditional materials break down quickly.

High-pressure fluid systems in aerospace hydraulics necessitate lightweight parts with remarkable strength-to-weight ratios.​​​​​​​

Quality Inspection

100% NDT Verification: Ultrasonic testing (UT) in compliance with ASTM B381 and AMS 2631 is used to identify internal discontinuities. Dye Penetrant Inspection (DPI) is used to identify surface defects.

PMI Analysis: X-ray fluorescence spectroscopy confirms grade validity and chemical composition conformance, including palladium content for Grade 7.

Mechanical Testing: Tensile, yield, and elongation tests on particular samples are used to confirm the effectiveness of heat treatment and material properties.

Dimensional Validation: CMM inspection ensures that bolt hole position is precise and sealing surface roughness meets specification requirements.

Traceability Documentation: EN 10204 3.1/3.2 certificates with complete heat number traceability are included with every shipment.

FAQ

Q: What makes forged flanges superior to cast ones?

A: Forging creates the improved impact toughness and fatigue strength needed for high-pressure applications by eliminating porosity and producing continuous grain flow.

Q: What distinguishes Grade 2 from Grade 5?

A: In chemical situations, Grade 2 provides outstanding corrosion resistance. For subsea and high-pressure aircraft applications, Grade 5 has double the strength.

Q: Is it possible to attach titanium flanges to stainless steel?

A: Galvanic corrosion is a risk associated with a direct connection. When combining various metals, use insulation kits (sleeves and washers) to electrically isolate them.

Q: What is the highest temperature at which it can operate?

A: Standard titanium flanges function dependably between 400°C and 500°C. It is advised to use alternative materials or specialty alloys beyond this range.

Q: How could galling be avoided during installation?

A: To avoid thread seizure and guarantee correct torque application, use MoS2 lubricants or silver-plated bolts and nuts.
