Types of Carbon Steel Blind Flanges
Blind carbon steel flanges are designed to provide a reliable and leak-free seal. They are
manufactured using high-quality carbon steel, which offers excellent strength and durability. The
flanges are precisely machined to ensure accurate dimensions and proper fitment. The sealing surface
of blind carbon steel flanges can be raised face, flat face, or ring type joint (RTJ), depending on
the application and sealing requirements.
- Raised Face Blind Flange: This type of blind flange features a raised face on the sealing
surface, providing a larger contact area for improved sealing and stability.
- Flat Face Blind Flange: Flat face blind flanges have a flat sealing surface, resulting in
a flush connection when installed.
- Ring Type Joint (RTJ) Blind Flange: RTJ blind flanges have a groove machined into the
sealing face, allowing for the use of a metallic ring gasket.
- Male-Female (MF) Blind Flange: MF blind flanges have a male face on one flange and a
corresponding female face on the other.
- Tongue and Groove Blind Flange: This type of blind flange has a raised tongue on one
flange and a matching groove on the other.

Uses of Carbon Steel Blind Flanges
Blind carbon steel flanges are frequently employed during pressure testing procedures. By attaching a
blind flange to the end of a pipeline, the system can be isolated, allowing pressure to build up for
testing purposes. The blind flange effectively seals the pipe, preventing any leakage during the
pressure testing process. When maintenance or repairs are required on a section of piping, blind
carbon steel flanges can be used to seal off that specific area.
Quality of Carbon Steel Blind Flanges
The quality of the material used in manufacturing blind carbon steel flanges is vital. carbon steel
is commonly chosen for its strength, durability, and resistance to corrosion. High-quality blind
flanges are typically made from carbon steel that meets stringent industry standards, ensuring
long-lasting performance even in demanding environments. Blind Carbon Steel flanges should be
manufactured in compliance with recognized standards such as ANSI (American National Standards
Institute) or ASME (American Society of Mechanical Engineers).
