Titanium Blind Flange Raised Face Ti Gr2 Gr7 BLRF for Oil and Gas
Pipelines
1. Product Introduction of ASME B16.5 Titanium Blind Flange
ASME B16.5 Standard:
Scope: ASME B16.5 covers dimensions, tolerances, materials,
marking, and testing for pipe flanges and flanged fittings.
Class 300: Class 300 flanges are designed to withstand higher
pressures compared to Class 150. They are rated for pressures up to
300 pounds per square inch (psi) at ambient temperatures.
Titanium Grades:
Titanium Grade 2 (Ti Gr2): Commercially pure titanium (CP titanium)
Grade 2 offers excellent corrosion resistance, formability, and
weldability, making it suitable for various industrial applications
where these properties are essential.
Titanium Grade 7 (Ti Gr7): Titanium Grade 7 contains palladium,
enhancing its corrosion resistance in reducing and mildly oxidizing
environments. It is particularly useful in chemical processing and
marine applications.
2. Product Information of Titanium Blind Flange
A titanium blind flange is a type of pipe flange made from titanium that is characterized
by its solid disk-like design without a central bore. It is
commonly used to cap off the end of a pipeline or to close off a
vessel or a pipe system temporarily or permanently.
Material and Construction:
- Titanium: Known for its exceptional corrosion resistance, titanium is used
in blind flanges to withstand aggressive environments such as
chemical processing, marine applications, and aerospace.
- Solid Disk Design: Unlike other flanges that have a center hole, blind flanges are
solid in the center, providing a sealed closure for pipelines.
Function and Applications:
- Pipeline Cap: Blind flanges are primarily used to seal the end of pipelines that
require closure. This can be for maintenance purposes, temporary
shutdowns, or as a permanent seal.
- Access Point: Once installed, a blind flange provides a point of access to the
pipeline system. It can be easily removed when necessary to allow
inspection, cleaning, or modification of the pipeline.
- Adaptability: Blind flanges can be machined to accommodate various pipe sizes.
They can be customized with standard-sized pipe connections, such
as threaded or welded downsizes, to fit specific piping
requirements.
Benefits:
- Secure Seal: Provides a secure and leak-proof seal when installed properly.
- Versatility: Suitable for a wide range of industries including chemical
processing, oil and gas, marine, aerospace, and more.
- Durability: Titanium blind flanges are durable and resistant to corrosion,
making them suitable for harsh operating conditions.
