Types and uses of flanges and series products

introduce

Pipe flanges are important components in many piping and industrial systems. They connect pipes, valves and other equipment, ensuring joints are leak-free and strong. While there are many types of flanges available, this blog is intended to provide an overview of the most commonly used flanges, including black iron pipe flanges,threaded pipe flanges, blind flanges, and metal pipe flanges. So, let’s dive into the world of pipe flanges and explore their features and applications.

Black iron pipe flange

Black iron pipe flange
Black iron pipe flanges are usually made of cast iron or malleable iron. They are strong, durable, resistant to corrosion and extreme temperatures. These flanges are commonly used in gas piping systems, water piping, and HVAC applications. The screw-in connection of the black iron pipe flange ensures a tight seal, making it suitable for high-pressure environments.

Threaded pipe flange

Threaded pipe flange
Threaded pipe flanges have internal threads in the inner bore to provide a secure connection. These flanges are compatible with externally threaded pipe and are easy to assemble and disassemble. Threaded pipe flanges are versatile and suitable for use in low pressure systems such as domestic pipes, water supply networks and small industrial pipes.

Blind flange

Blind flange

Blind flanges, also called blind or cover flanges, are used when a piping system requires temporary or permanent closure. These flanges do not have a center opening and are bolted to the end of a pipe or flange to stop the flow of fluid or gas. Blind flanges are commonly used in pipelines, oil and gas pipelines, chemical processing plants and offshore drilling rigs.


Pipe flange joint

Pipe flange joint
A flange joint in a pipe is formed when two flanges are bolted together with a gasket sandwiched between them. This fitting provides a tight seal and prevents leakage, even under high pressure. Flange joints are commonly used in industrial piping systems such as those found in refineries, chemical plants and power plants.
Flange Gasket
Flange Gasket
Flange gasket is used in pipeline flange connection, for the sealing between the two pieces of flange, medium, pressure and temperature directly affect the selection of flange gasket.Winding gasket refers to the use of metal tape (generally v-type steel tape) and non-metallic tape winding into a ring gasket, metal tape and non-metallic tape alternately winding, because of its good elasticity, widely used in petrochemical, chemical, electric power and other industries in the flange sealing structure, according to the specific parts of the gasket can be added in the inner or outer layer of the gasket with a steel ring to locate or strengthen.

in conclusion

Pipe flanges play a vital role in ensuring the efficient operation of pipelines and industrial systems. Understanding the different types of flanges, such as black iron pipe flanges, threaded pipe flanges, blind flanges, and metal pipe flanges, allows for better selection based on specific application requirements. Whether connecting pipes, closing lines or creating safety joints, the variety of flanges available ensures that every industry can find the perfect solution for their needs.
