Introduction
Carbon steel is a widely used material in piping and industrial systems. Among its components, carbon flanges hold a vital role. They connect pipes, valves, and equipment to form a strong and leak-proof system.
Flanges also allow easy cleaning, inspection, or replacement of parts. Carbon steel flanges are known for durability, affordability, and high-pressure resistance. Companies like Fortis Forge manufacture these flanges under strict international standards.
This blog explores the types, uses, standards, and installation practices of carbon flanges. It also highlights their advantages in different industries.
What Are Carbon Flanges?
Carbon flanges are pipe connectors made from carbon steel. They join pipes and equipment together using bolts, nuts, and gaskets.
Carbon steel provides strength and durability while remaining cost-effective. Flanges are available in different pressure ratings and face types.
Benefits of carbon flanges include:
High pressure resistance
Cost-effectiveness
Easy installation
Versatility in industries
Types of Carbon Flanges
1. Weld Neck Flange
A long tapered hub provides smooth stress distribution.
Used in high-pressure and high-temperature applications.
2. Slip-On Flange
Easy to install and align.
Best for low-pressure piping systems.
3. Blind Flange
Seals pipe ends or valves.
Used for maintenance and pressure testing.
4. Socket Weld Flange
The pipe fits into a socket for welding.
Suitable for small-bore high-pressure pipes.
5. Lap Joint Flange
Works with a stub end fitting.
Allows easy dismantling in piping systems.
6. Threaded Flange
Connected without welding.
Ideal for explosive or flammable environments.
7. Orifice Flange
Contains holes for flow measurement instruments.
Used in industries requiring accurate flow monitoring.
Applications of Carbon Flanges
