What is a forged threaded joint fitting?
Forged Threaded 45 degree Elbow claim to be one of the oldest types of forged fittings that have been used for ages. Threaded fittings are used for piping applications where pipes have smaller bore and diameter. The ideal nominal diameter of the pipe using threaded fitting should be around 2 NPS or smaller.
What are the benefits of using threaded forged fittings?
- The use of Forged Threaded 45 degree Elbow means a reduced number of types of equipment.
- Using threaded fittings ensures a reduced number of joints.
- Numerous pieces of equipment can be joined easily using a male or female thread.
- There is no need for any special piece of equipment to install a threaded fitting.
Here are a few essential tips one should keep in mind while installing forged threaded fittings:
- Always use a male PVC thread in the female threads. Doing the reverse of this process might cause the pipe to split.
- Always wind the thread tape in the same direction as the thread. This ensures a safe and durable seal.
- Do not use hemp on threads. Hemps expand when they come in contact with water. This can result in the breakage of the pipe.
Uses of forged threaded fittings
One thing to always remember is that forged threaded fittings are not suitable for high-pressure applications.
Thus, these are the common applications that use Forged threaded fittings:
- Water Distribution
- Cooling system
- Fire Hydrants and Fire Protection, etc.
Let us have a glance at a few types of Threaded Fittings:
- Threaded Elbow Fitting:
There are two main types of Elbow Fittings-
- Threaded 90-degree elbow
- Threaded 45-degree elbow
Threaded 90-degree elbows are used for pipes that make a 90-degrees angle change.
Threaded 45-degree elbows are used for pipes that make a 45-degree angle change.
- Threaded Tee Connection Fitting:
This fitting makes a perpendicular or a 90-degree branch from the main pipe.
The two types of tee fittings are:
- Equal tee: The size of the Branch and the Main pipe are equal
- Reducing tee: The size of the branch pipe is relatively smaller than that of the main pipe.
- Threaded Cross Fitting:
A threaded cross fitting is a four-way connecting joint. This fitting has one inlet and three outlets. The flow of substances is split between three directions. Cross fittings generally have female threads and assure secure connections.
- Threaded Coupling Fittings:
These fittings are available in the form of full and half couplings.
- Threaded Caps:
Threaded Piping Caps are used to seal pipe ends.
- Threaded Plug:
A threaded plug is used to seal or blind a joint.
There are three types of threaded plugs:
- Threaded Square plugs
- Hex Head Plugs
- Round Head Plugs
- Threaded Bushing:
These fittings have a hex or hexagonal shaped head and its application is joining threaded pipes of varying sizes.
- Threaded Union:
Threaded unions consist of three interconnected elements. There are two main types of the threaded union-
- Male to Female
- Female to Female
A lug nut is used to connect the pieces of equipment.
