Titanium Blind Flange (Ti Gr2, Ti Gr5, Ti Gr7) ASME B16.5 Class 150 Raised Face BLRF for Pipeline Applications

Product Overview: ASME B16.5 Titanium Blind Flange

The ASME B16.5 Class 150 titanium blind flange is a type of flange manufactured according to the ASME B16.5 standard, specifically designed for low-pressure applications. It is available in various titanium grades such as Titanium Grade 2 (Ti Gr2), Titanium Grade 5 (Ti Gr5), and Titanium Grade 7 (Ti Gr7). Below is a detailed description of the ASME B16.5 Class 150 titanium blind flange:

ASME B16.5 Standard:

• Scope: ASME B16.5 outlines specifications for the dimensions, tolerances, materials, markings, and testing procedures of pipe flanges and related fittings.
• Class 150: The Class 150 designation indicates that the flange is rated for a pressure of up to 150 psi under standard ambient temperature conditions. This pressure rating makes it suitable for low-pressure applications.

Titanium Grades:

• Titanium Grade 2 (Ti Gr2): This grade is commercially pure titanium (CP titanium), known for its excellent corrosion resistance, formability, and weldability. It is widely used in various industrial sectors due to these properties.

• Titanium Grade 5 (Ti Gr5): Also known as Ti-6Al-4V, this titanium alloy contains 90% titanium, 6% aluminum, and 4% vanadium. It is highly valued in the aerospace, marine, and chemical processing industries for its high strength, toughness, and resistance to heat.

• Titanium Grade 7 (Ti Gr7): Titanium Grade 7 contains a small amount of palladium (0.15%), which enhances its corrosion resistance, especially in reducing and mildly oxidizing environments. This makes it an ideal material for highly corrosive environments such as chemical processing and marine applications.

Design Features:

• Face Type: The blind flange may come with different face types, including Raised Face (RF), Flat Face (FF), or Ring Type Joint (RTJ), depending on the sealing needs of the application.

• Dimensions: The ASME B16.5 standard provides precise specifications for dimensions such as the outside diameter (OD), bolt circle diameter (BC), bolt hole diameter (BH), and overall thickness (T). These dimensions ensure that the flanges are compatible with other ASME B16.5 flanges, enabling easy interchangeability.

Titanium Grades for ASME B16.5 Titanium Blind Flange

Titanium Grade 2 (Ti-CP):

Titanium Grade 7 (Ti-0.15Pd):

• Composition: Titanium alloy with 0.15% palladium.

• Properties:

  • Corrosion Resistance: Outstanding resistance to corrosion, especially in reducing environments.
  • Weldability: Good weldability, suitable for welding and fabrication.
  • Strength: Lower strength than Grade 5 but still sufficient for many applications.

• Applications: Primarily used in chemical processing, desalination plants, marine environments, and applications requiring superior corrosion resistance.

Benefits of Using Titanium Flanges

1. Superior Corrosion Resistance: Titanium is immune to rust and corrosion in environments like seawater, acidic solutions, and other chemically aggressive media. This extends the lifespan of the flange and reduces maintenance costs.
2. Lightweight: Titanium alloys, particularly Ti Gr2 and Ti Gr5, are known for their lightweight yet strong properties. This is particularly advantageous in aerospace and high-performance engineering applications where weight is a critical factor.
3. High-Temperature Resistance: Titanium performs well under both low and high-temperature conditions. Ti Gr5 can withstand temperatures up to 600°F (316°C), and Ti Gr2 can handle temperatures up to 450°F (232°C).
4. Excellent Fatigue Resistance: Titanium is highly resistant to fatigue, which ensures that the flange performs reliably over an extended period, even under cyclical or fluctuating pressure conditions.
5. Improved Durability: Titanium alloys exhibit outstanding durability, meaning components made from these materials are less likely to suffer from damage over time, reducing the need for replacements.

Applications of Titanium Flanges

• Chemical Processing: Titanium flanges, particularly Ti Gr2, are ideal for applications where pipelines carry chemicals, acids, or other aggressive fluids. Their resistance to corrosion ensures safety and reduces the likelihood of leaks.
• Marine and Offshore: In marine environments, where seawater can rapidly degrade standard materials, titanium flanges are used for high-performance and long-lasting sealing.
• Aerospace: In the aerospace industry, the need for lightweight yet strong materials is paramount. Titanium's excellent strength-to-weight ratio and resistance to corrosion make it an ideal choice for flanges used in aircraft or rocket systems.
• Desalination Plants: Titanium flanges are widely used in desalination facilities where they help in processing seawater into fresh water, enduring both high pressure and corrosive seawater conditions.
• Power Generation: Used in power plants, especially those dealing with high-temperature fluids and chemicals, titanium provides a long service life.

Key Features and Advantages of ASME B16.5 Titanium Blind Flanges

• High-Quality Standards: Conforms to the ASME B16.5 standard, ensuring proper dimensions, pressure ratings, and flange compatibility.
• Robust Sealing Capabilities: The raised face design enhances the flange's ability to form tight seals when used with gaskets, improving the overall integrity of the piping system.
• Ease of Installation: The standard bolt hole pattern and bolt circle dimensions make it easy to install and replace when required.
• Cost-Effective Over Time: Despite the higher upfront material cost, the reduced maintenance requirements and longer lifespan make titanium flanges a cost-effective choice in the long run.

Technical Specifications

Titanium Blind Flange Inspection

EN 10204/3.1B Certificate:

The EN 10204/3.1B certificate is a standard document that verifies the titanium alloy used in the flange manufacturing process meets the required specifications. It includes detailed information on the chemical composition and mechanical properties of the material, confirming its compliance with relevant standards. This certificate is issued by the manufacturer, ensuring that the material conforms to the necessary criteria.

Raw Materials Certificate:

The raw materials certificate provides a comprehensive overview of the materials used to manufacture the titanium flanges. It outlines essential details such as the source of the raw materials, their chemical composition, and any test results from material inspections. This document ensures full traceability and quality control starting from the raw material acquisition phase.

100% Ultrasonic Flaw Detection:

Ultrasonic testing (UT) is a non-destructive method employed to identify any internal or surface imperfections within the titanium flanges. A 100% UT coverage means that every single flange is subjected to a complete and thorough inspection to detect potential flaws, ensuring that the flanges are free of defects that could affect their performance or structural integrity.

Hydrostatic Test:

During the hydrostatic test, the titanium flange is subjected to a liquid (usually water) pressurization process to assess its ability to endure the specified pressure without any leaks or deformation. This test ensures that the flange can safely handle the required pressure ratings and meet the necessary safety standards.

Third-Party Inspection Report:

A third-party inspection report is conducted by an independent inspection agency, providing an impartial assessment of the titanium flanges' quality. This report verifies that the flanges meet the relevant standards, specifications, and customer requirements, adding an additional layer of assurance and credibility to the manufacturer's quality control procedures.
