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.

higher strength-to-weight ratio, ideal for applications requiring
both strength and reduced weight. |
| Leak-Proof Sealing | Raised Face design ensures a secure, leak-proof seal under high
pressure, preventing leaks and improving system reliability. |
| Temperature Resistance | Suitable for high-temperature environments, ensuring stable
performance without degradation. |
| Long Service Life | The durability of titanium alloys ensures reduced maintenance needs
and extended service life, which is cost-effective in the long run. |
Material Grades:
| Material Grade | Composition | Advantages |
|---|
| Ti Gr2 | Pure Titanium (99.2% Ti) | Excellent corrosion resistance, good formability, cost-effective
for general applications. |
| Ti Gr5 | Ti-6Al-4V (Titanium alloy with 6% Aluminum and 4% Vanadium) | High strength, lightweight, corrosion-resistant, ideal for
aerospace and high-performance applications. |
| Ti Gr7 | Ti-0.2Pd (Titanium with 0.2% Palladium) | Outstanding resistance to acids, chlorides, and reducing
environments, perfect for chemical processing. |
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:
- Material Selection: High-quality titanium billets are selected based on the desired
material grade (Gr2, Gr5, or Gr7).
- 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.
- Heat Treatment: The titanium flanges undergo heat treatment processes to enhance
their mechanical properties and resistance to corrosion.
- Surface Finish: The raised face of the flanges is machined to ensure a perfect
seal surface, providing a leak-proof connection.
- 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.
