GB/T 16598 Standards Class 150 Titanium Blind Flange Ti Gr2 Gr5 Gr7 for Pipeline Applications ASME B16.5 Raised Face BLRF

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

The ASME B16.5 Class 150 Raised Face Blind Flange (BLRF) made from Titanium Grades Gr2, Gr5, and Gr7 is a high-performance flange designed specifically for demanding pipeline applications in industries such as chemical processing, petrochemical, aerospace, and more. These titanium flanges offer superior corrosion resistance, high strength, and reliable sealing properties for critical systems that need to withstand extreme conditions.

These BLRF (Blind Flange Raised Face) flanges are part of the ASME B16.5 standard and are engineered for Class 150 pressure ratings. They are specifically used for closing off pipeline sections, providing secure, leak-proof seals under high-pressure and high-temperature conditions. Titanium alloys, with their excellent resistance to corrosion and fatigue, are ideal for environments where traditional materials like steel would degrade over time.

Key Features:

• Material Grades: Available in Titanium Gr2, Titanium Gr5 (Ti-6Al-4V), and Titanium Gr7 (Ti-0.2Pd), each offering distinct advantages depending on the application.

  • Gr2: Offers superior ductility and excellent corrosion resistance.
  • Gr5: Known for high strength and lightweight properties, especially suitable for aerospace and high-strength applications.
  • Gr7: Provides excellent corrosion resistance in both oxidizing and reducing environments, ideal for chemical processing.

• Pressure Rating: Class 150, suitable for medium-pressure pipeline systems, providing high resistance to internal and external stresses.

• Flange Type: Blind Flange (BLRF), designed for sealing pipeline ends and providing a secure, leak-tight closure.

• Sealing Surface: Raised Face configuration ensures an effective seal between flanges, reducing the risk of leaks and improving the reliability of the pipeline system.

Manufacturing Process:

These Titanium Blind Flanges are produced through a precise forging process, ensuring the highest level of strength and durability. The steps involved include:

1. Material Selection: High-quality titanium billets are selected based on the desired material grade (Gr2, Gr5, or Gr7).
2. Forging: Titanium billets are heated and forged into the desired shape to create the flanges, followed by precise machining to achieve the correct dimensions and tolerances.
3. Heat Treatment: The titanium flanges undergo heat treatment processes to enhance their mechanical properties and resistance to corrosion.
4. Surface Finish: The raised face of the flanges is machined to ensure a perfect seal surface, providing a leak-proof connection.
5. Inspection & Testing: All flanges undergo rigorous inspection, including dimensional checks and non-destructive testing (such as ultrasonic testing) to ensure they meet the required standards and specifications.

Applications:

These Titanium BLRF Flanges are primarily used in high-demand pipeline applications where corrosion resistance, strength, and durability are essential. Some of the key industries and applications include:

• Chemical Processing Plants: Handling aggressive chemicals and corrosive substances.
• Petrochemical Industry: Suitable for high-temperature, high-pressure applications.
• Aerospace: Lightweight, high-strength flanges used in critical aerospace applications.
• Marine & Offshore: Resilient to saltwater and corrosive elements, ideal for marine pipelines and equipment.
• Power Generation: High strength and corrosion resistance for systems exposed to high pressures and temperatures.
