About Threaded Flange :-
A Threaded Flange, also known as a Screwed Flange, is a type of flange used primarily in low-pressure, non-critical applications where welding is not feasible or desirable. Unlike other flange types that require welding, a threaded flange has an internal thread that matches the external thread of the pipe, allowing it to be screwed onto the pipe directly. This design makes threaded flanges easy to install and remove, making them ideal for systems requiring frequent disassembly, such as temporary piping systems or maintenance operations.
The most distinguishing feature of a Threaded Flange is the tapered threading, which provides a secure and leak-resistant fit between the pipe and the flange. This taper, which typically follows the NPT (National Pipe Thread) or BSP (British Standard Pipe) threading standards, creates a tight seal as the flange is screwed onto the pipe. Because there is no welding involved, the heat-affected zone is eliminated, which is advantageous for installations in environments where heat exposure must be minimized or in systems with special alloys sensitive to high temperatures.
Threaded flanges are commonly used in applications with low to moderate pressure levels, typically under 300 psi, and are often seen in industries like plumbing, water treatment, and low-pressure chemical processing. However, they are not suitable for systems with high vibration or cyclic loading, as the threads could loosen over time. They are also not recommended for use in high-pressure or high-temperature environments due to the limitations of a threaded connection’s sealing integrity.
In terms of materials, Threaded Flanges are often made from carbon steel, stainless steel, or alloy steels, allowing them to meet the specific needs of the application, particularly in corrosive environments. They are manufactured in compliance with industry standards such as ASME B16.5 and ANSI, ensuring their suitability for various piping applications.
These flanges are valued for their ease of installation and removal, making them a cost-effective and convenient choice for systems where welding is impractical or costly. They offer a practical solution for simple and low-pressure applications while maintaining flexibility and reliability in piping systems.

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.
We Export Threaded Flange to United States (USA), Canada, Germany, Japan, France, Middle-East, Bangladesh, Nepal etc.

How do I ensure a leak-free connection with a Threaded Flange?
Applying a thread sealant or Teflon tape, tightening to the manufacturer’s specifications, and using a suitable gasket can help ensure a leak-free connection.
Are Threaded Flanges suitable for underground piping?
Threaded Flanges can be used in underground piping if they are made from corrosion-resistant materials and properly sealed. However, regular inspection or protective coatings are recommended.
Can Threaded Flanges handle vibrations in piping systems?
While Threaded Flanges can withstand some vibration, excessive vibration may loosen the threads over time, so it’s essential to check regularly or consider additional supports.
What are the temperature limits for Threaded Flanges?
