Grade 5 Titanium Flange – A Reliable Solution for Aerospace, Automotive, Electronics, and Energy Industries

I. Product Introduction:

Name: Grade 5 Titanium Flange
SKU: N/A

Titanium flanges are key connecting components in piping systems, made from Gr2 or premium titanium alloys,such as Gr5、Gr7 and Gr12,valued for their excellent corrosion resistance, high specific strength, and compatibility with extreme environments. They are widely used in petrochemical, marine, aerospace, and pharmaceutical industries where traditional steel flanges fail to meet performance requirements.

Because of its special advantages, the Titanium Flange plays an important role in industries like aerospace, automotive, energy, and electronics.

II. Classification:

Here means classification by Structural Type which is mostly used in engineering, and this is the most widely recognized classification in industrial applications, based on the connection mode with pipelines.Please see the tables below:

Flange Type	Abbr.	Structural Characteristics	Installation	Advantages
Weld Neck Flange	WN	Integral neck design, thickened hub, smooth transition between flange and pipe	Welded connection with pipe	high strength, good stress distribution; suitable for high-pressure, high-temperature, and vibration-prone systems
Slip On Flange	SO	Flat disc structure with a central bore for pipe to slip through, then welded (fillet weld on both sides)	Easy alignment during installation, lower cost than WN flanges	suitable for medium and low-pressure pipelines
Blind Flange	BL	Solid disc without a central bore	Used to seal the end of pipelines or equipment openings	Easy to disassemble for maintenance and inspection
Threaded Flange	TH	Internal threads on the central bore, connected to threaded pipes	No welding required	Suitable for pipelines that cannot be welded (e.g., flammable, explosive media) or low-pressure systems
Lap Joint Flange	LJ	Matched with lap joint stub ends; flange can rotate freely on the stub end	Convenient for pipeline alignment, reusable	Suitable for corrosion-resistant alloy pipelines (e.g., titanium, stainless steel)

III. Technical Specifications:

This kind of Titanium Flange is available in various sizes and grades to suit different applications. please see the attached for your options as below:

Specification	Value
Material	Grade 5
Standards	ASTM B381, ASME B16.5,GB/T9112-2010,EN 1092-1
Tensile Strength	345–1000 MPa (grade-dependent)
Size	DN10–DN2000 (NPS ½"–48") (custom sizes acceptable)
Thickness	5 mm to 100 mm
Pressure Rating	Up to 1500 psi depending on material and size
Sealing Face	RF (Raised Face), FF (Flat Face), RJ (Ring Joint)
Temperature Resistance	Up to 600°C (varies by the naterial)
Corrosion Resistance	Excellent ------ resistant to acids, seawater, and high-temperature environments
Finish	Smooth, polished, or custom finishes

IV. Key Performance Advantages:

1. Corrosion Resistance: Withstands seawater, acids, and chloride environments (corrosion rate <0.01 mm/year).

2. High Strength-to-Weight Ratio: Reduces installation load and transportation costs vs. steel flanges.

3. Biocompatibility: Safe for food, pharmaceutical, and medical applications.

4 .Temperature Stability: Operates reliably from cryogenic (-253°C) to moderate high temperatures (≤300°C for Gr2; ≤400°C for Gr5).

V. Typical Applications:

1. Chemical/Petrochemical: Acid recovery, chlor-alkali plants, and high-purity fluid handling.

2. Marine Engineering: Offshore pipelines, desalination systems, and shipbuilding.

3. Food/Pharmaceutical: High-purity processing lines requiring non-contamination.

4. Aerospace/Nuclear: Rocket propulsion systems, reactor cooling loops, and vacuum chambers.
