Threaded Fitting
Threaded stainless steel pipe fittings resist corrosion from caustic chemicals, corrosive fluids, oils, and gases, and withstand pressure and high temperatures in plumbing applications and food and dairy processing. Threaded pipe fittings are threaded on both connection ends. Female threads are on the inside of a fitting. Male threads are on the outside of a fitting and screw into the female threads. NPT (American National Standard Pipe Threads) and BSPT (British Standard Pipe Threads) threads are distinguishable by their thread taper angle. There are also straight (NPS) pipe thread fittings and metric (M) pipe fittings. Metric pipe fittings are identified by the nominal outside diameter and the thread pitch. These connections do not require glue or adhesive, but PTFE tape keeps seal tight. Threaded fittings come in a variety of sizes and shapes.
Definition and Use
Threaded fittings are commonly used connecting elements in piping systems, which realize a firm connection between pipes or piping accessories through the close fit of internal and external threads. Threaded fittings are widely used in a variety of low-pressure, non-critical fluid transmission systems, such as domestic water, fire fighting, industrial cooling water, and so on.
Types and Shapes
Threaded fittings come in a variety of shapes and types, including but not limited to:
Elbows
Used to change the direction of piping, common angles are 45°, 90° and 180°.
01
Tees
Used to branch out from the main pipe to another pipe, there are equal and reducer tees.
02
Tee
Similar to tee, but can branch out from the main pipe to two pipes.
03
Pipe Cap (End Cap)
Used to close the end of the pipe.
04
Plugs
Including square-head plugs, hexagonal-head plugs and round-head plugs, etc., used to seal the threaded ends of pipes or fittings.

Materials and Manufacturing
Threaded fittings are usually made from materials such as gray cast iron, malleable cast iron, stainless steel, brass, bronze, forged alloys and carbon steel. These materials have good mechanical properties and corrosion resistance to meet the needs of different piping systems.
The manufacturing process of threaded fittings includes steps such as forging, casting and thread machining. Among them, forging and casting are the main manufacturing processes, which can produce threaded fittings with complex shapes and precise dimensions. Thread machining is to machine internal and external threads on the fittings by turning, milling or grinding.
Connection and Sealing
Threaded fittings make connections between pipes or pipe accessories by means of threaded connections. During the connection process, a sealing material (e.g. Teflon tape or sealant) is used to ensure a tight connection. Correct installation and tightening torque are essential to ensure a tight threaded connection.

Advantages of Threaded Fitting
The high strength of threaded fitting: According to the principle of cold work hardening of steel, the strength of the straight thread rolled on the steel bar is greatly improved, so that the tensile strength of the straight thread joint is higher than the tensile strength of the steel base material.
Stable performance: The joint process is not affected by the quality of workers, so the performance is stable.
Fast connection speed: Because methods of prefabricating off-site and assembling on-site are used, the prefabricated rebar can be stored in a large amount of prefabricated steel bar. When the construction period is tight, you only need to add assembly workers at the construction site.
Wide range of application: There are basically no restrictions on the range of application, and threaded pipe for sale is more suitable for the field where bending steel bars, fixed steel bars, steel bar cages and other steel bars cannot rotate.
Easy to manage: The threaded fitting like aluminum pipe nipple will not have a mismatch between the sleeve and the steel bar, and the inspection is more convenient. The operation is simple, and ordinary workers can become skilled workers after a few hours of study.
Significant economic and social benefits: The use of threaded fitting shortens the construction period, improves the quality of the project, reduces energy consumption, is beneficial to environmental protection, reduces equipment investment, and has low additional costs. It has obvious economic and social benefits.

Precautions for Use Threaded Fitting
Clean the threads of fittings with a wire brush or cloth to remove any dirt, debris, or rust that may interfere with the sealing of the joint. Apply thread sealant to the male threads of the fitting. The sealant helps to lubricate the threads and prevent leaks.
Over-tightening can cause the fitting to crack or damage the pipe. Tighten the fitting until it is snug, and then use a wrench to turn it an additional 1/4 to 1/2 turn. Another option for sealing the threads is to use Teflon tape. Wrap the tape around the male threads of the fitting in a clockwise direction to prevent the tape from unraveling during installation. Once you have installed the fittings, test for leaks. Turn on the water or gas supply and check for any leaks. If you detect a leak, tighten the fitting a little more.
