Advantages of Threaded Flanges

01/

Accessibility For Maintenance

Threaded connections are easy to disassemble, making maintenance and repair more straightforward. This accessibility is especially valuable in systems where components may need frequent inspection or replacement.

02/

Cost-effective

Threaded flanges are often more budget-friendly than flange types requiring welding. Since they eliminate the need for welding labor and equipment, they can lead to cost savings in material and labor expenses.

03/

No Heat-affected Zone (HAZ)

Unlike welded connections that create a heat-affected zone (HAZ), threaded connections do not introduce heat into the pipe material.

04/

Reduced Risk Of Welding Defects

Welding can introduce defects such as porosity, cracks, or incomplete penetration.

05/

Leak Resistance

When properly sealed with thread sealant or tape, threaded flanges provide a strong, leak-resistant connection and prevent fluid or gas from escaping.

06/

Reduced fire hazard

In applications where fire safety is a concern, threaded flanges can be advantageous.

Application of Threaded Flanges

Water treatment and supply systems
In water treatment plants, threaded flanges are used for low-pressure connections that require secure, yet easily modifiable joints. Whether it’s freshwater or waste treatment, these flanges allow easy maintenance of piping systems without significant downtime.

Compressed air systems
For applications like compressed air distribution, threaded flanges are an ideal choice. These systems generally operate at a lower pressure, making threaded connections practical. The ability to unscrew and reseal the connections also ensures quick fixes to any leaks or system adjustments.

Fire protection and sprinkler systems
Fire suppression systems often use threaded flanges for their piping. Since these systems are low-pressure and sometimes require quick assembly, threaded flanges are the preferred choice. They also allow for swift and safe disassembly during inspections or when replacing outdated components.

Non-hazardous gas piping
In situations where low-pressure gas (like natural gas or propane) is transported, threaded flanges are a safe and practical option. Since there is no welding involved, there’s less risk when dealing with combustible gases, making them suitable for residential or light commercial gas supply systems.

Irrigation and agricultural systems
Threaded flanges are widely used in agricultural settings, particularly for irrigation systems. They allow farmers to quickly extend or modify their irrigation networks based on crop layout changes or seasonal needs.

Safety Precautions

Always wear appropriate personal protective equipment (PPE).
Be cautious of hot fluids or surfaces.
Ensure the work area is well-ventilated, especially when dealing with chemicals.

FAQ

Q: What is the difference between a slip-on flange and a threaded flange?

A: Threaded Flanges: Similar to slip-on flanges but with internal threads, allowing them to be screwed onto the pipe. They are used in low-pressure systems and can be easily assembled and disassembled.

Q: How to use a threaded pipe flange?

A: Threaded flanges work by screwing the threaded pipe into the female-threaded interior surface on the flange. Once the pipe is securely tightened, the required gasket can be placed between the flange connection's two raised faces to ensure a tight seal.

Q: What is the purpose of a threaded flange?

A: Threaded flanges are used where it is difficult to weld or cannot be welded, such as threaded flanges used to protect the galvanized layer of pipes. In addition, It should not be used on pipes with repeated temperature fluctuations or above 260 ℃ and below -45℃ as well.

Q: What size are threaded flanges?

A: The most popular threaded flanges range in ½ inch to 6” nominal pipe size, but we are able to offer NPT threaded flanges up to 24” if necessary.

Q: What is the purpose of the threads on a threaded flange?

A: The threads allow for easy assembly and disassembly of the piping system. They provide a mechanical connection that can be tightened to create a seal, preventing fluid or gas leakage between the connected components.

Q: How do you ensure a proper seal with a threaded flange?

A: Using thread sealants such as Teflon tape or pipe dope is common. Also, tightening the flange to the appropriate torque specification is crucial. Over - tightening can damage the threads or the flange, while under - Tightening may lead to leaks.
