Contrary to all the flange types seen above, blind flanges do not have a center hole, and are used to blind or seal a pipeline, a valve/pressure vessel and block the flow of the fluid.
Blind flanges have to withstand remarkable mechanical stress due to the system pressure and the required bolting forces. Blind flanges allow easy access to the pipeline, as they can be easily unbolted to let the operator execute activities inside the terminal end of the pipe (this is also the reason why the blind flange type is used as a manhole for pressure vessels, at times). It is maybe interesting to observe that, while this flanges type is easier to manufacture, they are sold at a premium average cost per kilogram compared to the other flange types.

Threaded Flange

Threaded stainless steel flanges are usually between ½ inch and 4 inches in size. They are threaded and therefore screwed onto the pipe rather than welded. Threaded flanges can be used in systems where welding is not possible. The dimensions of threaded asme b16.5 flanges vary according to requirements, but their diameters are usually less than the NPS 4 standard. Some pn16 npt flanges can withstand pressures of up to 16 bar. There are different types such as BSP flanges that can be used to screw in two pipes with different diameters. Flanges with national pipe thread or npt thread are a variant of flanges.

ASME B16.5 threaded flanges can be used to connect two pipes with different diameters through the hole to make a joint. If welding is not a problem and pressures are high, threaded welding neck flanges can be used and welded to seal the joint for added strength and leak resistance. The range of bsp flanges is also available in various pressure classes, such as Ansi 150 threaded flange dimensions. Depending on requirements, threaded reducing flanges according to ASME B16.5 are also used to connect different pipe sizes. They are used in all types of flow systems and hydraulics. Prices for threaded flanges in India vary according to supply and demand, including transportation costs and location.

Frequently Asked Questions

Most frequent questions and answers

What is the purpose of a threaded flange?

A threaded flange is a type of flange that has threads on the inside of the flange bore, rather than a raised or flat face. The purpose of this design is to allow for a pipe or fitting to be screwed into the flange, rather than being welded or bolted to it. This can be useful in situations where frequent disassembly or maintenance is required, as it allows for easy removal and replacement of the pipe or fitting without the need to cut or weld. Additionally, the threaded flange can be used to connect two pipes or fittings that have different dimensions, as the threads can be used to adjust the size of the connection.

What is a threaded connection?

Threaded connection is a type of mechanical joint used to connect two components together. The connection is made by fastening threads, which are protruding ridges or grooves, onto the end of one component and mating it with a complementary threaded hole on the other component. This allows the two components to be screwed together, creating a secure and stable connection. Threaded connections are commonly used in plumbing, machinery, and other mechanical systems.

 

What are the different types of threaded flanges?

There are two types of threaded flanges: raised face (RF) and flat face (FF). The raised face type has a small raised ring around the bore, while the flat face type has a smooth, flat surface.

How are threaded flanges connected?

Threaded flanges are connected by threading the flange onto a pipe or other component with a complementary thread. They are typically used with a gasket and bolts to provide a secure seal.

 

What are the advantages of using threaded flanges?

Threaded flanges are easy to install and remove, making them ideal for maintenance and repair work. They are also relatively inexpensive and can be used in low-pressure applications.

What are the disadvantages of using threaded flanges?

Threaded flanges are not suitable for high-pressure or high-temperature applications as they may not provide a secure seal under these conditions. They also have a lower pressure rating compared to other types of flanges.

 

What is a threaded flange?

A threaded flange is a type of flange that is used to connect pipes or other cylindrical components together. It has a circular base with a series of threads on the inside of the flange, which are used to connect the flange to a pipe or other component with a complementary thread. Threaded flanges are typically used in low-pressure applications and are not as common as other types of flanges such as weld neck, slip-on, and blind flanges.

Threaded flanges are also known as screw flanges and are typically used in low pressure and non-critical applications. They are easy to install and remove, but not suitable for high pressure and high temperature service, as the threads may not provide a secure seal under these conditions.

Can I use a threaded flange in a high-pressure application?

It is not recommended to use threaded flanges in high-pressure applications as they may not provide a secure seal. Other types of flanges such as weld neck or slip-on flanges are better suited for high-pressure applications.
