PVC (polyvinyl chloride) pipe fittings are widely used in pipe systems in residential, industrial, agricultural and other fields. 2 inch pvc pipe fittings are widely used in water supply, drainage, gas pipelines and other systems due to their corrosion resistance, durability and easy installation. Among the many PVC pipe fittings, 2-inch threaded pipe fittings play an important role in connection and maintenance due to their flexibility and strength. This article will introduce the characteristics, size, application and selection considerations of 2 inch threaded pvc pipe fittings in detail.
What are 2 inch threaded pvc pipe fittings?
2 inch threaded pvc pipe fittings refer to PVC pipe fittings with a nominal diameter of 2 inches, with threaded interfaces, and are usually used in parts of the piping system that need to be connected or disassembled. Unlike ordinary flat pipe fittings, threaded pipe fittings are connected by spiral threads, allowing pipes to be connected and disassembled without the use of adhesives or other accessories. threaded pvc pipe fittings are widely used in home, commercial and industrial environments, and are suitable for occasions with low temperatures and pressures that do not exceed the tolerance of PVC pipes.
Types of 2 inch threaded pvc pipe fittings
1. Couplings
The most common type of 2 inch threaded pvc pipe fittings is used to connect two pipes. Through the cooperation of internal and external threads, threaded couplings can firmly connect two sections of pipes together, which is convenient for disassembly and maintenance.
2. Elbows
Threaded elbows are used for pipe turns. Common threaded elbows include 90-degree elbows and 45-degree elbows. Their internal and external threaded interfaces can be tightly connected to the pipe to help the pipe system change direction.
3. Tees
Threaded tees are used to divide a pipe into two branches. One of its ports is straight, and the other two ports are side openings, which can be connected to other pipes through threads.
4. Plugs
Threaded plugs are used to close the end of the pipe to prevent external substances from entering the pipe system. Through the threaded interface, the threaded plug can be firmly fixed on the pipe and is usually used in applications where the pipe needs to be closed or isolated.
5. Threaded flanges
Threaded flanges are used to connect PVC pipes to other equipment or pipes. The threaded interface of the flange is convenient for quick installation and removal, and is commonly used in industries such as water treatment and chemical transmission.
2 inch threaded pvc pipe fittings dimensions
The dimensions of 2 inch threaded PVC pipe fittings are expressed in nominal diameter (NPS), usually corresponding to an outer diameter (OD) of 2.375 inches and an inner diameter (ID) of 2.095 inches. The thread size varies according to the type of fitting, and common thread standards include NPT (National Pipe Thread) and BSP (British Standard Pipe). NPT threads are mainly used in the United States, while BSP threads are more common in Europe and other regions.
The following is a table of dimensions for some common threaded PVC pipe fittings (NPT threads):
| Pipe fitting types | Nominal diameter（NPS） | Outer diameter（OD） | Thread size（NPT） |
| Thread Connectors | 2 inch | 2.375 inch | 2 inch NPT |
| Thread elbow | 2 inch | 2.375 inch | 2 inch NPT |
| Thread Tee | 2 inch | 2.375 inch | 2 inch NPT |
| Threaded plug | 2 inch | 2.375 inch | 2 inch NPT |
| Thread Flange | 2 inch | 2.375 inch | 2 inch NPT |
Different types of pipe fittings may differ in length, interface angle, etc., but the outer diameter and thread size are relatively standardized. The choice of pipe fittings should be determined according to the specific needs of the pipeline system.
Features and Benefits
1. Corrosion resistance
PVC material has strong chemical corrosion resistance and can effectively resist erosion by chemicals such as acid, alkali and salt. This makes 2 inch threaded pvc pipe fittings widely used in chemical industry, sewage treatment and agricultural irrigation.
2. Easy installation
2-inch threaded PVC pipe fittings use threaded connection, which is very easy to install. You only need to tighten it with a wrench, without the need to use glue or other chemical adhesives. This greatly simplifies the installation process and saves construction time.
3. Lightweight and economical
PVC material is lighter than metal pipes and is easier to carry and install. At the same time, the low cost of PVC pipe fittings makes it an affordable choice in a variety of piping systems.
4. Removability
A significant advantage of threaded connections is the ease of disassembly and repair. Unlike welded or bonded fittings, threaded fittings can be easily disassembled, making it easier to maintain, inspect and replace pipes later.
5. Good sealing
2 inch pvc pipe fittings can provide good sealing performance and prevent leakage through the tight fit of threads. This is a very important point in the piping system, especially in the transportation of high pressure or corrosive liquids.
Application areas
1. Residential water supply system
2 inch threaded pvc pipe fittings are often used in household water supply pipes, especially in cold water pipe systems, because of their good sealing and corrosion resistance, they can ensure the stable operation of the water supply system.
2. Agricultural irrigation system
In agricultural irrigation, they are often used to connect different pipes to ensure the smooth flow of water and the stable operation of the system.
3. Industrial piping system
Due to the high pressure bearing capacity and corrosion resistance of PVC pipe fittings, they are widely used in piping systems in industries such as chemical industry, food processing, pharmaceuticals and sewage treatment.
4. Water treatment facilities
2 inch pvc pipe fittings are widely used in water treatment facilities, especially in piping systems for conveying water, wastewater or chemicals.
Things to note when choosing 2 inch threaded pvc pipe fittings
1. Choose the thread type appropriately
Make sure to choose the correct thread standard (NPT or BSP) to ensure compatibility with the piping system.
2. Ensure the pressure rating of the fittings
When used in a high-pressure environment, it is necessary to ensure that the pressure-bearing capacity of the selected fittings meets the system requirements.
3. Check the temperature resistance of the fittings
PVC fittings usually have a temperature resistance range of -10°C to 60°C. Too high or too low temperatures may affect their performance, so it is necessary to choose fittings that are suitable for the working environment.
4. Check quality certification
Choose fittings with certified standards, such as ASTM standards, ISO certification, etc., to ensure the quality and safety of the fittings.
2 inch threaded pvc pipe fittings have been widely used in various piping systems for their advantages such as easy installation, corrosion resistance, and affordability. They not only provide reliable connections, but also have strong durability and good sealing, and are suitable for residential, agricultural, industrial and other fields. Understanding its size, type, characteristics and application areas will help users better select and use threaded pvc pipe fittings, thereby improving the efficiency and stability of the piping system.
