The threaded flange design (also called a 'screwed flange') uses a screw thread to connect the flange to a pipe. A male thread is cut onto a pipe end whilst a female thread is cut into the bore of the flange; the male threaded pipe is then screwed into the female threaded flange.
Screwed flanges, also known as threaded flanges, are a type of pipe flange that is designed to be connected to pipes by screwing them together. These flanges have threads on the inner bore, which allows them to be easily attached to threaded pipes or fittings without the need for welding. The threads on the flange and the pipe create a strong and secure connection, making them a popular choice in applications where welding is not practical or desired.

Connection Method:
Screwed flanges are connected to pipes or fittings by screwing them together. This connection method is simpler compared to welding and allows for easier disassembly and reassembly of the components.
Advantages:
Ease of Installation: Screwed flanges can be easily installed and removed without the need for specialized tools or welding equipment.
Versatility: They can be used with a variety of pipes and fittings that have matching threads.
Cost-Effective: The installation and maintenance costs are often lower compared to welding, making screwed flanges a cost-effective choice for certain applications.
Limitations:
Pressure and Temperature: Screwed flanges are not suitable for high-pressure or high-temperature applications as compared to welded flanges.
Seal Integrity: Achieving a reliable seal can be challenging, and the joint may be more prone to leaks compared to welded connections.
Standardization: Screwed flanges are manufactured in accordance with industry standards such as ANSI, ASME, and other international standards. This ensures compatibility and interchangeability between components from different manufacturers.
When selecting screwed flanges, it's crucial to consider the specific requirements of the application, including pressure, temperature, and compatibility with the fluids being transported. Additionally, proper installation and torqueing of the threaded connections are essential to ensure a secure and leak-free joint.

What is a Reducing Flanges?
The threaded flange design (also known as the'screwed flange') connects the flange to a pipe via a screw thread. A male thread is cut onto a pipe end, and a female thread is cut into the bore of the flange; the male threaded pipe is then screwed onto the female threaded flange.
Although threaded flanges are available in many sizes and pressure ratings, they are typically utilised for small piping systems (≤ 4 inches). Its applications are typically limited to non-toxic, low-pressure, and low-temperature systems. ½ inch to 2-inch size threaded flanges are far more prevalent than diameters of 2 inches and higher. Threaded flanges only have flat and raised faces since they are used under lower pressures. They are unsuitable for high-temperature applications because the thread shape distorts, causing leakage.
The main advantage of threaded flanges is that they can be attached to a pipe without the requirement for welding. Forming joints without the need for welding is a significant advantage, and it is required in some locations and sectors, such as explosive zones (Ex rated areas) such as petrol stations, hexane facilities, flammable fluid depots, and so on. If no welding is necessary, a potential source of ignition is removed. Another advantage of threaded flange joints is that they are faster and easier to construct and disassemble than welded flanges.
Screwed Flanges Uses
Screwed flanges are useful for creating a secure connection between two sections of pipe. They are generally utilised in plumbing and industrial applications that require a watertight closure without the use of welding or soldering. Instead, a threaded nut is utilised to connect the two pipes. This enables for simple installation and removal, if necessary.
Screwed Flanges Welding
Screwed flanges are self-sealing, therefore welding is not necessary. This makes them excellent for applications where welding would be difficult or impracticable due to time restrictions or safety concerns. Furthermore, because no welding is required, there is no need for costly equipment or increased labour expenses connected with welding.
Screwed Flanges Types
Screwed flanges are classified into three types: slip-on, weld neck, and threaded flanges. Each variety offers distinct features and benefits, so choose the one that best suits your wants and requirements. Slip-on flanges are most typically used in low-pressure systems, but weld neck flanges are ideal for high-pressure systems because they offer greater stability and strength than other forms of flanged connections. Threaded flanges provide the maximum level of security since they require a threaded nut to properly attach the two pipes together.
