Introduction
In industrial piping systems, flanges are essential components. Among them, the CS Blind Flange holds a special place. It is designed to close pipe ends and provide strength to the entire system.
At Fortis Forge, we manufacture high-quality CS Blind Flanges that meet global standards. This blog explains their features, types, applications, and benefits.
What is a CS Blind Flange?
A CS Blind Flange is a solid disk made from carbon steel. Unlike other flanges, it has no opening. Its main function is to stop flow at the pipe end.
These flanges are bolted into place and can be removed when required. They are strong, durable, and ideal for high-pressure systems.
Importance of CS Blind Flanges
Blind flanges are crucial for pipeline safety. They allow maintenance without disturbing the entire system.
Key functions include:
Closing pipeline ends securely
Allowing pressure testing
Providing easy access for inspection
Ensuring system safety under pressure
Types of CS Blind Flanges
Different industries use different types of CS Blind Flanges. Fortis Forge manufactures all major types.
1. Raised Face Blind Flange
Most common type
Provides better sealing with gaskets
2. Flat Face Blind Flange
Used with flat face valves or equipment
Ideal for low-pressure systems
3. Ring-Type Joint (RTJ) Blind Flange
Designed for high-pressure applications
Ensures tight metal-to-metal sealing
