What Are Carbon Steel Flanges?
Carbon steel flanges are pipe connection components used to join piping sections, valves, pumps, and process equipment. They are typically bolted together with a gasket placed between mating surfaces to create a secure and leak-resistant seal.
These components provide flexibility for maintenance, inspection, cleaning, and future modifications within industrial piping systems.
Types of Carbon Steel Flanges
Weld Neck Flanges
Designed for high-pressure applications, these flanges provide excellent strength and stress distribution.
Slip-On Flanges
Installed by sliding over the pipe before welding, making them suitable for low to moderate pressure systems.
Blind Flanges
Used to seal the end of a piping system and allow future expansion or inspection.
Socket Weld Flanges
Commonly used in smaller-diameter piping systems where strong connections are required.
Threaded Flanges
Feature internal threads that eliminate the need for welding during installation.
Lap Joint Flanges
Used with stub ends and preferred in systems requiring frequent dismantling.
Orifice Flanges
Designed for flow measurement and monitoring applications.
