The Threaded Union is a detachable union system based on the combination of two pieces, in one of which a helical thread has been carved on the outside and in the other (usually called a nut) a complementary helical thread on the inside. To make the joint, the screw must be rotated concerning the nut around the axis of the propeller.
Usually, the system includes one or more pieces between the screw and the nut, which are compressed and joined together when the screw is tightened on the nut. Threaded joints have the following main advantages:
- They are detachable unions without the need to destroy the union
- The system is standard and interchangeable
- Ease of assembly and disassembly
- Allows the union of pieces of different materials
- If well-designed, they resist tensile, shear, bending, and torsion loads well.
Steel pipe elbows are important in plumbing piping systems and are used to change liquids' directions. There are different types depending on the material: carbon steel elbow, stainless steel elbow and alloy steel elbow.
Types of Carbon Steel Elbows and their Uses
In simple words, the steel elbow is a type of connection that joins two pipes. The main objective is to change the direction of the liquids that pass through the pipe. Stainless steel globe valve suppliers usually made material at 45-degree, 90 degree and 180-degree. Other grade types, like 60 and 120, can also be found in piping systems, but this only happens in cases with special requirements.
The 90 Degree Steel Elbow for Steel Pipe is the most widely used
As its name explains, the 90-degree steel pipe elbow is to change the direction of the liquid by 90 degrees, also known as the vertical elbow. This type of elbow is the most used in piping systems since it is compatible with steel structures and construction.
- Long Radius 90 Degree Elbow
This type of 90 Degree Threaded Elbow is installed between tubes or pipes of different lengths.
It is commonly used in hose connections to water pumps, deck drains, and valves.
- Short Radius 90 Degree Elbow
Its main use is the same as the above elbow, except that its radius is short. So this type of pipe elbow is mostly used when the pipe installation does not have enough space.
- 45 Degree Elbow for Steel Pipe
45 degree Threaded Elbow is used to change the direction of the pipeline by 45 degrees. It is the second type commonly used in industrial pipelines.
- Long Radius 45 Degree Elbow
Long Radius 45 Degree Elbow is installed between two pipes to change direction at a 45-degree angle. Because it generates less frictional resistance, the pressure passing through the pipe is also less.
- Short Radius 45 Degree Elbow
This elbow is typically used on copper, plastic, steel, cast iron, and lead pipe. It can also be used to connect stainless steel and rubber clamps. Due to its versatility, it is used in pipes in the chemical industry, food and water supply installations, electronics, gardening and agricultural production, pipes for solar energy installations, and pipes for air conditioning.
