Types of elbows and the introduction for the elbow usage

Pipe elbow plays a very important role in the pressure pipe system, usually made of PVC pipe elbow, PPR pipe elbow, stainless steel elbow, etc. Elbows not only can make the pipeline change the direction in the pipeline system, but also plays an important role that increases the flexibility of the PVC pipe, and reduces the vibration and the restraint of the pipes. And the PVC pipe elbow can compensate for the thermal expansion, so it’s an important part in the pressurized pipe. The elbow is most stressed in the pipeline, and is therefore the most vulnerable part of the pipeline.

According to the angle division, there are common 45 degree elbow, 90 degree elbow, also some unusual angle elbow such as 60 degree elbow. Because of the different needs of the pipeline, the pipe elbow angle is also different.

According to the material division, there are PVC pipe elbow, PPR pipe elbow, PE pipe elbow, CPVC pipe elbow, stainless steel pipe elbow, malleable cast iron pipe elbow and so on.

According to the way with the pipe connection, there are flange connection, hot melt connection, threaded connection and socket connection.

According to the production process division, there are injection elbow, casting elbow and so on.

According to the radius of curvature division, there are long radius elbow and short radius elbow (long radius elbow that its curvature radius is equal to 1.5 times the outer diameter of the pipe; short radius pipe elbow that its radius of curvature is equal to the outer diameter of the tube.

In accordance with the use of different shapes to divide, there are flange elbow, reducing elbow, female and male thread elbow, socket elbow and so on.

The pipe elbow is suitable for a pipe fitting at the pipe turn. It can be divided into socket elbow and thread elbow according to the connection method. The most popular pipe elbow used in the pipe system is socket elbow. Generally, we choose different forming process according to different materials and wall thicknesses. At present, the factory commonly use injection techniques to produce PVC pipe elbow.

Because the pipe elbow has a good comprehensive performance, it is widely used in chemical engineering, construction, water supply, drainage, oil, light and heavy industry, freezing, sanitation, plumbing, fire, electricity, aerospace, shipbuilding and other basic projects.

Requires control of the radius of curvature. For example, if the radius length is 1.5D, the radius of curvature must be within the required tolerance range. Since most of these fittings are used for sockets. The pipe elbow surface quality and mechanical properties of the basic and the tube is the same.
