Stainless steel (SS) flanges come in various types, each designed for specific applications and installation requirements. Here are some common types of stainless steel flanges and their corresponding applications.
BLIND FLANGES
These flanges are perfect for capping vessel openings or piping systems without a bore in vessels or piping systems that need routine inspection. It is possible to utilize hub-less or hub-less blind flanges. The flange can easily sustain significant tension due to internal pressure.
FLANGES WITH WELD NECKS
The necks of these flanges are prominent, making them simple to spot. Weld neck flanges are made to endure extremely high pressures and temperatures and will match the pipe’s diameter and bevel.
SOCKET WELD FLANGES
These flanges are used in the chemical processing industry since they were designed for high-pressure pipelines with small diameters. The strength of their fatigue resistance is enhanced by the internal welding of the socket weld flanges.
SLIP-ON FLANGES
These Stainless Steel 304 Flanges are welded to a spot and because of their wider diameter than the pipe, they are ideal for low-pressure applications. Since they are welded to a specific place, they can easily be slipped over the pipe.
LAP JOINT FLANGES
A type of slip-on flange is one constructed of low alloy steel or carbon steel that can be utilized with stub end fittings. They are ideal for installation on pipeline systems, such as low alloy steel or carbon steel pipes, that require routine inspection and maintenance.
THREADED FLANGES
These flanges can be used for a variety of purposes, and they can be put together without the use of welding. Stainless steel threaded flanges are best used with externally threaded pipes, although they shouldn’t be used in extreme pressure or temperature conditions.
RING TYPE JOINT FLANGES
High-pressure and high-temperature applications use flanges with ring-type joints. The ring-type joint flanges have a groove that can be easily squeezed on blind, slip-on, or weld neck flanges. The flanges help keep pipelines that deliver media under high pressures and temperatures from leaking.
ORIFICE FLANGES
These steel flanges are used to access a line so that liquids or gases can be metered via it. The orifice flanges are used to insert orifice plates or flow nozzles.
