45° Threaded Elbow

The dimensions of the 45° threaded elbow mainly include the nominal diameter (DN), the outer diameter of the end, the center-to-end dimension, the center-to-center dimension, the back-to-end dimension, etc. The specific size range is from DN15 to DN600, covering a variety of specifications, including but not limited to:

1. DN15 45° threaded elbow, the end outer diameter is 18mm, the center-to-end dimension is 38mm, the center-to-center dimension is 16mm, and the back-to-end dimension is 20mm.

2. DN25 45° threaded elbow, the end outer diameter is 25mm, the center-to-end dimension is 76mm, the center-to-center dimension is 22mm, and the back-to-end dimension is 25mm.

3. DN40 45° threaded elbow, the end outer diameter is 32mm, the center-to-end dimension is 95mm, the center-to-center dimension is 32mm, and the back-to-end dimension is 40mm.

4. The end outer diameter and specific dimensions of the DN600 45° thread elbow are not found in the information provided, but it can be inferred that its size is larger and suitable for large pipeline systems.

These dimensions provide a specific reference when selecting and using 45° thread elbows, ensuring compatibility and safety with the pipeline system.

45° threaded elbow is a kind of pipe fitting used to connect pipes. Its main purpose is to change the direction of the pipe. It is usually used in main pipes and branch pipes. It is connected by thread, including direct welding, flange connection, hot melt connection, electric fusion connection, threaded connection and socket connection, etc., to meet different installation requirements.

45° threaded elbows are made of cast iron, stainless steel, alloy steel, malleable cast iron, carbon steel, non-ferrous metals and plastics. ‌

45° threaded elbows, also known as threaded elbows, are used to change the direction of pipes in piping systems. There are many types of materials, including but not limited to:

‌1. Cast iron: It has good corrosion resistance and wear resistance, and is suitable for piping systems that need to withstand certain pressures and temperatures.

‌2. Stainless steel: It has excellent corrosion resistance and is suitable for industries that require high hygiene standards such as chemical industry and food processing.

3. Alloy steel: It improves strength and corrosion resistance by adding alloy elements, and is suitable for high temperature and high pressure industrial environments.

‌4. Malleable cast iron: It has good toughness and strength, and is suitable for piping systems that need to withstand impact and vibration.

‌5. Carbon steel: It has low cost and is suitable for general industrial piping systems.

‌6. Non-ferrous metals: Such as copper, aluminum alloys, etc., have good electrical and thermal conductivity, and are suitable for piping systems in special environments.

‌7. Plastics‌: Suitable for piping systems that require lightweight and corrosion resistance, such as drinking water supply systems.

The choice of these materials depends on the specific application environment and performance requirements to ensure the safe and reliable operation of the piping system‌.

The specifications of 45° threaded elbows involve multiple aspects of information, including nominal diameter, end outer diameter, center-to-face dimension, center-to-center dimension, and back-to-face dimension. These dimensions vary according to the different series of elbows (A series and B series), radius type (long radius and short radius), and specific angles (45°, 90°, and 180°). Here are some specific examples of specifications:

‌1. The nominal diameter (DN) and the end outer diameter have a wide range of sizes, such as from DN15 to DN2500, and the specific values depend on the type and specification of the elbow.

‌2. The center-to-face dimension and the center-to-center dimension are also important parameters in the elbow specifications, which determine the installation and use of the elbow in the pipeline.

‌3. The back-to-face dimension is related to the connection method of the elbow with other pipes or equipment, which is crucial to ensure the sealing and functionality of the entire system.

45° threaded elbow is a commonly used pipe connector, mainly used to change the direction of the pipe. Its usage mainly includes the following aspects:

1. Connection method: 45° threaded elbow can be connected to other pipes by threaded connection. This connection method is suitable for occasions that require frequent disassembly and maintenance. By rotating the connector, the pipe can be easily connected or disconnected from the elbow, which is convenient for maintenance and replacement.

2. Material selection: 45° threaded elbow can be made of different materials, such as stainless steel, carbon steel, alloy steel, copper, aluminum alloy, etc. The specific choice depends on the use environment and needs. For example, stainless steel elbow has good corrosion resistance and is suitable for environments that transport corrosive media.

3. Production process: According to different production processes, 45° threaded elbows can be divided into welding elbows, stamping elbows, push elbows, casting elbows, etc. Choosing a suitable production process can ensure that the quality and performance of the elbow meet the use requirements.

‌4. Angle selection‌: In addition to the common 45° elbow, there are also 90° and 180° elbows of other angles to choose from. Choose the appropriate angle according to the specific pipeline layout and steering requirements.

‌5. Installation and maintenance‌: When installing the 45° threaded elbow, make sure that all connections are tight and secure to prevent leakage. During use, check the connection regularly for looseness or damage, and repair or replace it in time.
