A Threaded Fittings are essential components in piping systems. They allow for secure connections between pipes, valves, and other fittings. These fittings are designed to ensure leak-proof connections and are widely used in various applications, including plumbing, oil and gas, and chemical processing.

1. Couplings: Used to connect two pipes. They can be straight or reduced in size.

2. Elbows: Allow for a change in direction in a piping system, commonly available in 90-degree and 45-degree angles.

3. Tees: Used to connect three pipes, allowing for a branch line off the main pipe.

4. Crosses: Similar to tees but allow for four connections, typically forming a cross shape.

5. Adapters: Used to connect pipes of different types or sizes, such as male to female threads.

6. Caps: Close off the end of a pipe, preventing flow.

7. Plugs: Similar to caps but usually have male threads, used to seal the end of a pipe.

8. Nipples: Short sections of pipe with male threads on both ends, used to connect two fittings.

9. Bushings: Used to connect pipes of different sizes, reducing the diameter.

10. Union: Allows for easy disconnection of two pipes without cutting, typically featuring three parts: two nuts and a central body.

1. Plumbing: Used in water supply and drainage systems for connecting pipes, faucets, and fixtures.

2. Gas Lines: Commonly used in natural gas and propane systems for safe connections between pipes and appliances.

3. HVAC Systems: Utilized in heating, ventilation, and air conditioning systems for connecting ductwork and piping.

4. Industrial Piping: Employed in chemical processing, oil and gas, and manufacturing to connect pipes, valves, and equipment.

5. Automotive: Used in fuel lines and exhaust systems for secure connections that can withstand vibrations.

6. Marine Applications: Applied in shipbuilding for connecting pipes and components in harsh environments.

7. Fire Protection Systems: Used in sprinkler systems and fire hydrants for reliable and secure connections.

8. Home Appliances: Found in various appliances like washing machines and dishwashers for plumbing connections.

9. Construction: Used in scaffolding and structural supports where temporary or adjustable connections are needed.

10. Electrical Applications: Employed in conduit fittings to connect electrical conduits securely.

Ease of Installation: The design of threaded fittings allows for quick and straightforward assembly without the need for specialized tools.

Reusability: Unlike welded fittings, threaded fittings can be easily removed and reused, making them cost-effective for projects requiring frequent alterations.

Versatility: They are available in various materials, sizes, and thread types, allowing them to be used in numerous applications across different industries.

Seal Integrity: When properly installed, threaded fittings provide a strong seal that can withstand significant pressure and temperature variations, reducing the risk of leaks.

When selecting threaded fittings, it is crucial to consider the material compatibility with the fluids being transported, the pressure and temperature ratings, and the specific thread type required for the application. Additionally, proper installation techniques are vital to ensure that fittings are secured without over-tightening, which can lead to damage or failure.
