Threaded Flange

A threaded flange means the inner bore of the flange is a thread, the shape of the threaded flange is like the slip-on flange, so the threaded flange could be plate shape or with a hub for the longer threads.

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.

Uses:

A pipe flange allows for easy connection and interchangeability between pipes and apparatus as they are designed to have standardized dimensions.

Most commonly used to connect pipes, fittings, valves, pumps, and other equipment without the need to weld.

Threaded Pipe Flanges are generally used on smaller thread sizes and smaller pipe diameters. (Usually 3" and below.)

Types of Threaded Flanges

Standard Threaded Flanges
Standard threaded flanges are the most common type and are intended for general-purpose applications. The pipes have external threads that mate with their internal threading for a simple, dependable connection. These flanges are ideal for moderate-pressure systems where welding is infeasible or undesirable.

Raised Face (RF) Threaded Flanges
Raised-face threaded flanges possess a face slightly raised from around the bore. This feature enhances the sealing capability by increasing the gasket area. Raised-face threaded flanges see wide application when a strong seal is desired, especially in high pressure or high temperature.

Flat Face (FF) Threaded Flanges
Flat-face threaded flanges have a smooth, flat contact surface. They are mainly used under low-pressure applications and where the mating flange or pipe has a flat face. This flat surface ensures an even distribution of pressure across the seal and is not likely to deform the gasket.

RTJ (Ring Type Joint) Threaded Flanges
RTJ flanges are specially designed with a machined groove on the face for a metal ring gasket. This provides an excellent seal, and because of this, they find great application in high-pressure and high-temperature industries such as oil and gas or chemical.

Material Options

Threaded flanges can be made from a variety of materials for different environments and media.

Carbon Steel:

General-purpose applications where high strength and low cost are required.

Stainless Steel:

Excellent resistance to corrosion, applicable in harsh or corrosive environments.

Alloy Steel:

Used in high-performance systems, including high-temperature and/or high-pressure systems.

Cast iron:

This is usually used for low-pressure, non-corrosive applications because of its inexpensiveness.

FAQ

Q: Where are threaded flanges used?

A: Threaded flanges are used in systems where welding is not possible or safe, such as low-pressure piping, temporary systems, and hazardous environments where heat could pose a risk.

Q: Are threaded flanges suitable for high-pressure systems?

A: No, threaded flanges are not suitable for high-pressure applications. They are best used for low-pressure and low-temperature systems.

Q: How do threaded flanges compare to welded connections?

A: Threaded flanges screw onto pipes without welding, making them easy to install and adjust. Welded connections are more permanent and suitable for higher pressures.

Q: Can threaded flanges be reused?

A: Yes, threaded flanges can be easily unscrewed, adjusted, and reused, making them practical for systems requiring frequent changes or maintenance.
